[Ben Collins (ben-collins)]

Need one bit of info. Did this work with any previous versions of Ubuntu or other distribution?

[Shaya Potter (spotter)]

I had a similar problem w/ a T60. For some reason why I upgraded to gutsy, sound disappeared. For some reason also by simply rmmoding the appropriate modules and then modprobing them back into place, sound returned (there might have been a reboot or two in between, as well as to a different kernel).

unsure what happened, did know it was driving me crazy for a day.

[venky80 (venky80)]

I have tried with Feisty and gutsy. Don't have a Dapper or an Edgy
installation to check.
hopefully it helps.
Nothing works reboots or anything, I have tried those with feisty
Thanks,
Venky

This appears to be fixed by an upstream patch that has gone into git. Please try 6.13 or 7.13 when it becomes available.

[venky80 (venky80)]

what does it mean?

[Christophe Dumez (hydr0g3n)]

I updated to kernel 2.6.22-6.13 and I still have no sound. I didn't have any sound on the previous 2.6.22 release either. But if I reboot on my kernel 2.6.20 my sound gets back.

I'm using up to date gutsy.

Here is the output given but tutorial given above:
http://pastebin.ca/537564

My soundcard is also and intel with a realtek chipset, very common.

I have a Fujitsu-Siemens Amilo M6453G

[Chris Cheney (ccheney)]

Ben,

The fix in 6.13 does not appear to be nearly enough to support the Realtek 268.

There isn't even a setup function for the 268 codec in:

struct hda_codec_preset snd_hda_preset_realtek[]

I am going to try to look into what is needed to actually support the 268 codec, but I looked in alsa git yesterday and I didn't see anything related to the 268 at all.

Chris

Sorry, but the code I was hoping that would fix this isn't in 6.13, it
will be in the next upload. You can check http://kernel.ubuntu.com/git
in the ubuntu/ubuntu-gutsty repo to see if what you are looking for is
in there.

[venky80 (venky80)]

Hi Ben
Oh Well I am sad, I thought INTEL is good towards Linux,
Thanks for keeping me posted.
Venky
P.S I have no idea as to how to look into the git for what is getting
updated!

[Chris Cheney (ccheney)]

Ben,

I am not sure if I am looking at it properly but

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-gutsy.git;a=blob;h=4776de93928b4b55fa78a2b570b40715a54b1f4d;hb=36c1aeac3968fa6ea0899e2c619a5c69a4350b52;f=sound/pci/hda/patch_realtek.c

does not seem to have any reference to the 268 codec except for 1 on line 687 and if I am reading the code correctly that doesn't even get executed for a 268 codec since there isn't any setup function, etc, for the 268.

However, I may be looking in the wrong place...

- Chris

[Chris Cheney (ccheney)]

Ben,

So I couldn't find the fix in your git repo but crimsun told me where it is upstream...

http://hg.alsa-project.org/alsa-kernel/rev/dd701601157b

I am going to apply it to my kernel and see how it fares.

Thanks,

Chris

[Mark Lockwood (biz-lockwom)]

I bought a Toshiba A205-S4577 and I've been trying to get the sound working for the past couple of days.

I went to Chris Cheney's link

http://hg.alsa-project.org/alsa-kernel/rev/dd701601157b

and applied the patch_realtek.c to ALSA 1.0.14, compiled it for hda-intel and installed it. If I specify 3stack for the model as a module parameter, PCM doesn't show up in the mixer, so model=auto seems to work best, but alas I still don't have sound even with this new patch supporting 268.

Would there be any additional technical differences between the Toshiba's configuration that would still prevent sound from working? This is very frustrating since everything else on this laptop is working flawlessly in Ubuntu.

[Mark Lockwood (biz-lockwom)]

Whenever I try to execute an application using audio in a terminal, I get the following error

ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'defaults.pcm.dmix.device'
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:3982:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default

Is there some way to set the default device? I still see PCM, Headphone, and Front as controllable mixers, but apparently nothing can access the card.

BTW, I'm running Ubuntu 7.04 with kernel version 2.6.20.16.28.1 with that patched ALSA 1.0.14.

[Alejandro Zunino (azunino)]

I have a Toshiba A205-S4577. I have tried the patch (Ubuntu 7.04 with kernel version 2.6.20-16-generic and alsa-1.0.14 installed from source). I have noticed this message in dmesg:

[ 2658.948000] hda_codec: Unknown model for ALC268, trying auto-probe from BIOS...
[ 2659.720000] ALSA /home/azunino/alsa-driver-1.0.14/pci/hda/../../alsa-kernel/pci/hda/patch_si3054.c:244: si3054: cannot initialize. EXT MID = 0000

I have tried with model=3stack and model=auto with no success. Perhaps this notebook has a different codec model???? In addition, alsamixer shows a PCM slider, but it does not show a mute/unmute button bellow the slider.

Attached you will find the output of cat /proc/asound/Intel/codec#0

Hi all!

I have the same problem and the same output of Alejandro with an Acer 6292...

So, there is something wrong, but I didn't understand
and I was wondering if you could solve or show a way to do it.

[Chris Cheney (ccheney)]

This patch is from 2.6.22-6.13 -> alsa-kernel mercurial changeset 5114. It includes a few other fixes besides just the Realtek ALC268 support.

I have not tested this patch yet, but I will try to test it later tonight.

Tested the patch, it appears to setup the mixer right but I still can't get any sound out of my system with it.

Also, I looked at the Realtek 4.06a driver and it no longer has ALC268 support in the code, it appears they are planning on using the official ALSA version whenever it happens to actually work. Although the Realtek 4.05f driver does have support for ALC268 in the code, it isn't listed as supported in the readme.txt. Also, I haven't tested to see if 4.05f actually works for my Toshiba laptop.

If someone wants to check to see if the "official" Realtek driver works it can be downloaded from:

ftp://152.104.238.19/pc/audio/realtek-linux-audiopack-4.05f.tar.bz2

Thanks for testing it out, oh I so wanted it to work. Do you know if we ever
have a solution for this?

Venky,

If no one else makes work fairly soon I will probably look over the
datasheet and try to figure it out myself. I am pretty busy with other
things at the moment, like working on getting into core-dev so I can
maintain OpenOffice. :)

I have Toshiba A205-S4577 w/ Realtek ALC268. I've been trying to solve this problem for over two weeks. I even tried installing Debian, but could get no sound. Actually, realizing that this is not just my problem is somewhat comforting. I'll watch here for help.

[Christophe Dumez (hydr0g3n)]

This might have no link at all but I've just realized that I only have sound if I'm using external speakers. I don't have any sound with the laptop speakers. I will try again with the old kernel later to see if there is a link or not.

[venky80 (venky80)]

realtek ALC268?

I was going through the list of bugs that had upstream patches attached to them, looking for those that would be included in the next kernel release.

This patch doesn't seem to fix problems for everyone yet. Or am I mistaken?

I have a Toshiba A205-S4607. Same problem...so frustrating. I have tried everything mentioned in the forums. No luck. Please help.

Yes, Amit, Realtek ALC268 remains unsupported.

Hi Amit,
I am pretty sure It is not working for A205-S4577 laptop owners. There are
some other users with different laptop models with same chipset who have had
success, but i think if the bug isnt fixed for the Toshiba model it
shouldn't be closed.

[Chris Cheney (ccheney)]

After reading the report about what is needed to fix the Toshiba ALC268 it does not look specific to Toshiba per say. It appears that some systems either initialize more of the ALC268 in their BIOS or just happen to work without the setup. But the setup that is supposed to fix the Toshiba according to the upstream bug report (I haven't tested it myself) is just to enable the amplifier for the speaker/headphones... which should be done for all systems not just Toshiba(?)

I am working on replacement ALC268 support for ALSA, that I will try to send to whoever is in charge of it for ALSA (if I can get it working), by following the datasheet and using rtlhdmon.exe information from inside Windows.

So far some of the things that are done in the ALC268 part of the driver look suspiciously wrong to me, but I don't have a working replacement yet so I may just be misunderstanding what it is actually doing.

Chris Cheney

[Chris Cheney (ccheney)]

I have a reimplemented version of the init function that works fine for the Toshiba A205-4577. I GET SOUND and its very loud too. :) I am now working to make the rest of the features per the datasheet work properly. Once I am done I will post a patch here and on the alsa devel list.

[Mark Lockwood (biz-lockwom)]

I downloaded the realtek10,11.tar.gz files from

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104

and then patched appropriately. Then, in /etc/modprobe.d/alsa-base I added the line (to an otherwise standard version)

options snd-hda-intel model=toshiba

Now the driver loads and alsamixer recognizes the device. However, only OSS-based applications work. Amarok uses the Xine engine which can now let me play music, or I can play things on FCEU (only two OSS-supporting apps I could find) but nothing works specifically for ALSA. I feel like I'm really close. Any suggestions? If I try and run an app supporting ALSA, on the terminal it says

ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'defaults.pcm.dmix.device'
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory

Hi all.
After a nightmare of reading many many posts I fixed my sound issues by just issuing
sudo chmod -R a+rwX /dev/snd/
and
sudo /etc/init.d/alsa-utils restart
according to the troubleshooting guide at http://alsa.opensrc.org/index.php/TroubleShooting

I think there is something fishy in the feisty setup which do not allow all users to rw these files.

Kindly

//Marcus

[Chris Cheney (ccheney)]

Marcus,

Which Realtek sound chip do you have? Just using chmod should not have corrected the problem if you have a Realtek ALC268.

Chris

[matheuu (matheuu)]

Hey Chris!
Where is the patch you've been working on? AND do you have some real easy instructions on how to implement it? Like exactly what to type(copy/paste) into my terminal?
I have an A200 Toshsat, same as Hannah (hi Hannah!) not sure which Realtek chip is in this thing. I just tried Marcus's chmod and it didnt work.

Cheers
Mat

[Chris Cheney (ccheney)]

This patch is not done, and probably does not work for capture. I am at the Gutsy Sprint this week so don't really have time to work on the driver until I get back home. But here is the entire replacement file patch_realtek.c that you can try out.

Chris

[Brian Mount (bvmou)]

Thank you very much Chris et al!

I applied the patch and succeeded in getting sound with the ALC268 codec . It seems that the presence of headphones does not mute the speakers, I may have applied the patch incorrectly or consider this a tangential bug report. To the extent it may be useful to fellow novices I added the steps I followed to Mat's thread at http://ubuntuforums.org/showthread.php?p=3000405#post3000405 -- if anyone has insight into the headphone issue a follow-up to that post would be very welcome. Thank you again.

I have the same problem with the headphones, but this is such a relief to
have sound after so long without it. Thanks again guys.

I confirm that my laptop internal speakers are not working because of 2.6.22 kernel. I booted on my 2.6.20 kernel and my laptop internal speakers are working again. On 2.6.22, sound is working if I plug in external speakers though : this is strange. I posted infos about my audio info here : http://pastebin.ca/537564

the same problem with Feisty on laptop Toshiba Satelitte A200-14D with kernel 2.6.20-16-generic

[venky80 (venky80)]

I tried to use the patch_realtek.c and hda_proc.C from the mentioned ALSA
site and patched my driver and installed it.
But i used the gutsy 2.6.22-8 kernel I can see the mixer but I can't hear
any sound.
Also realtek10.tar.gz and realtek11.tar.gz both contained just
patch_realtek.c I thought one was supposed to contain hda_proc.C
Could anyone suggest me the steps and what should I do to undo what I did
and redo it all over again. Did anyone upgrade the jernel and check it?

Hi Chris,
So will you be looking into fixing this for gutsy?
Thanks,

I am going to do my best to get it fixed for Gutsy but my top priority is to get OpenOffice 2.3 into Gutsy which is what I am currently working on. My laptop needs the fix as well so I am motivated to get it fixed. :)

Chris

[venky80 (venky80)]

Hi Chris,
Do you have sound working in some fashion in your a205 laptop running gutsy?
If yes would you be able to give me your patch_realtek.c and hda_proc.c
files?
Also do you have is running in 2.6.22-8 kernel?
I would be glad if I can get some sound from my laptop, don't care if it
doesn't have all features.
I am sure you are motivated lol wouldn't be bad if you can listen to some
songs while working on open office development.
Thank you,
Venky

Venky,

why don't you change to feisty? I can hear sound from
my laptop 'a205-s4577' with the patches above.

Venky,

The patch_realtek.c that I added to this thread on Jul 10 was what I used in 2.6.22. I didn't make any changes to hda_proc.c, I'm not sure if any are actually needed either. Currently I am running feisty without sound until I have time to work on it again due to other gutsy issues I am having.

Chris

[Enrico Sardi (enricoss)]

Hi all!

I followed the instructions of Alejandro Zunino and now I have sound on an Acer 6292 (I used realtek12.tar.gz).

Thanks

Enrico

[venky80 (venky80)]

Hi Brian, Chris and rest of the crowd
I successfully got the sound working in my Gutsy machine thanks to incredible amount of support from Brian and Chris ,
 who patiently responded to all of the questions posted by this noob.
Now I will try to put together a how to.
I tried installing in my feisty machine but I was unsucessful.

Laptop Toshiba A205-S4577
Distribution: Ubuntu 7.10 (Gutsy Gibbon)
Kernel: 2.6.22-8-generic
Date of last updates: 18th July 2007
Packages needed before installing new ALSA Drivers : build-essential libncurses4 libncurses5 libncurses5-dev ( I am not very sure which one worked)
1)Download alsa-drivers, alsa-firware, alsa-lib, alsa-util version 1.0.14 from ALSA.org and extract it into a directory named ALSA in desktop or your home
2) Replace patch_realtek.c and hda_proc.c in the ~ALSA/alsa-driver-1.0.14/alsa-kernel/pci/hda with the new files (I am attaching both)
3) Then do sudo ./configure sudo make and sudo make install in the following folders according to the order specified (order is important) ALSA lib , ALSA utils ALSA firmware and lastly ALSA drivers.
hopefully you will see no errors.
4) restart

Unmute the mixers see the following link for how the mixer will look like
http://bayimg.com/caEJMAaBB
the headphones channel would control the external speakers and line in channel will (unfortunately/fortunately) control the inbuilt speakers.

I am extremely happy thanks to Chris Cheney and Brian Mount once again.
I think I am going to freeze all updates till this gets patched in repository.

Good night and enjoy.
Cheers!
Venky

I can confim that the patch proposed by Chris (1000 thanks) worked for the audio of my shiny new laptop, a toshiba U305-S5077. Audio reproduces well.
Unfortunately, the mic level is really low. This laptop has a built in mic/camera, maybe there is some inconsistence with this. If you think it's of interest, I will collect all the info in the Debugging Page and paste it.
Thanks!

[venky80 (venky80)]

My mic isnt really working can you attach the snapshot of your mic settings?

I do not know exactly what do you mean with mic settings... In the sound control panel I have 2 slides for capture1 and capture2, and a chooser between Mic and Front Mic as input source (in options). I tried with various combination, but the evel of registration is eveytime very low (but there is some capture, I can hear it for example using skype callback). So I attach all the info requested in the DebuggindSoundProblems page.

By the way, is there a better way to test mic than using ekiga or skype callback? Sound recorder of gnome does not work... it seems t register and than plain refuses to play.

[venky80 (venky80)]

ya I was just curious what were the settings u chose for all those
parameters you listed mic/front mic what were the capture levels etc etc..
well guess mine doesn't work i have tried some combinations myself.
Thanks

Anyone looking at the microphone issue? I am available to test patches... to reboot in Vista to use VOIP is quite a bad thing, you know... :-)))

Thanks!

[Romano Giannetti (romano-giannetti)]

Hi,

I managed to enable the capture on this card. What I have done is:

- applied the method that suggested venky80:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/116326/comments/75

- on top of that, I changed the Makefile and hda_patch.h in the same directory
so that the 3054 modules was not called anymore,

- recompiled, rebooted and MY MIKE WORKS! (Just the external one, the internal one is muted).

Hope this helps someone.

My patch on top of the venky80 aforementioned patch:

Romano thanx!
tried here and it worked, but mic capture volume is very very low, same with you?

[Romano Giannetti (romano-giannetti)]

Not really. I can control the capture volume with the slide "capture", and the option in "mic". Capture1 --- which I suspect should be for the internal mic --- does not work, or is so low that I cannot notice it.

By the way, there is any application that I can use to monitor the capture level?
I'm abusing skype....

you can use Audacity ;)

I have the same error with my TOSHIBA A205-S4597 and solved with Alejandro Zunino patch https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/116326/comments/48

I'm so happy.. now I have sound in my ubuntu feisty fawn.

[Colin Darie (colinux)]

Since I installed Gutsy on my Toshiba P100-284, I don't have sound.
On Feisty it perfectly works with a custom DSDT (known bug in bios).
On Gutsy with the same custom DSDT, it doesn't work. I also tried with the lasts drivers alsa, with the patches of Chris.
I added options snd-hda-intel model=toshiba in /etc/modprobe.d/alsa-base, that doesn't change anything, same result with options snd-hda-intel model=auto.

If I boot with acpi=off, it works.

So I reinstalled alsa and linux-image-2.6.22-9-generic and here my outputs generated by alsa-info.sh : http://pastebin.ca/663258

If that can help, I can join my outputs with Feisty.

Thanks in advance for your replies.

[Jose Bernardo (bernardo-bandos)]

The upgrade from kernel 2.6.22-9 to 2.6.22-10 broke sound for me on a HDA intel. Previously, I only had the microphone issue.

I'll try it, but probably won't fix the issue - I had sound until the kernel upgrade, from 2.6.22-9 to 2.6.22-10

[Albert Damen (albrt)]

Up to kernel 2.6.22-9 I was able to get sound on my hda intel + realtek ALC268 by compiling alsa 1.0.14 with the files from realtek12.tar.
With the new kernel 2.6.22-10 this resulted in a not working snd-hda-intel module. Loading this module reported a missing symbol: snd_hda_intel: Unknown symbol snd_hwdep_new
Some googling learned this missing symbol could be solved by also compiling emu10k1 from alsa.
Compiling alsa 1.0.14 with the files from realtek12.tar with ./hgcompile --with-cards=hda-intel,emu10k1 brought back my sound.

[venky80 (venky80)]

Hi Albert,
Could you provide the steps in a little more detail?
I am a noob here.

I have a Toshiba U305 S5087, and i am running Debian, kernel version 2.6.22-1-686, ALSA version v1.0.14

After applying the patch realtek17 mentioned above:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104

And commenting out the modem support in the struct in the end of patch_si3054.c
http://jmaurer.awardspace.info/e8210/patch_si3054.diff

The sound output finally works. Although the mics arent working yet.

[Ben (ben-speakmon)]

Same story as Jose: running feisty with 2.6.20-16 and patches to alsa 1.0.14. hda-intel with realtek 268 worked fine once I compiled alsa myself.

Upgraded to gutsy kernel 2.6.22-10 to get my wireless working, which it now does, but now the sound fix doesn't work anymore. No combination of realtek.tar.gz patch from the alsa-project bug and the latest released alsa sources works. Something gets loaded, and I can control volume, but nothing is played.

[venky80 (venky80)]

I am not sure if Chris /Brian Mount have tried any patches to resolve this
issue, those were the guys who helped me last time..

[Mahdi (mahdi-hates-spam)]

Confirmed on a Toshiba Satellite A205 S4797 too...
venky80's procedure makes sound work, but I can't get Romano's patch to apply on those files =/
so, sound's ok thanks to Chris, Brian and venky80 (for the howto), but my mic still doesnt work....

that great improvement though! Tkz dudes! These changes MUST to go upstream, since this codec seems to be pretty popular :D

[Ben Collins (ben-collins)]

No clean patch for this other than hacks that may break existing hw, or not completely fix this hw.

[Mahdi (mahdi-hates-spam)]

Actually, seems like it already went upstream (http://git.kernel.org/?p=linux/kernel/g … 4b3d69e15d) and the new alsa just got merged (http://git.kernel.org/?p=linux/kernel/g … ;a=summary)!

It would be just VERY GOOD now if the kernel and alsa packages are updated on gutsy! The new kernel is reported to work with this codec on Arch linux (http://bbs.archlinux.org/viewtopic.php?pid=275445). That might be a good starting point!

[Mahdi (mahdi-hates-spam)]

[Romano Giannetti (romano-giannetti)]

Hmmm. Not sure what you meant for upstream, but I tried 2.6.23-rc5 vanilla and 2.6.23-rc5 with the latest alsa drivers (alsa-driver-hg20070901) and my card still does not work at all. No sound, no recording, none.

[Romano Giannetti (romano-giannetti)]

Tried with the standard feisty 2.6.20-16 kernel too, no joy. Same failure as with the upstream Linus' kernel.

[Mahdi (mahdi-hates-spam)]

Well, dunno, but its there :D
when it will be functional... that I really do not know....
you could diff hda_proc.c and patch_realtek.c and see weather its there or not... the alsa stuff might not have been merged yet.
http://git.kernel.org/?p=linux/kernel/git/perex/alsa.git;a=commit;h=a361d84bfcd938208dea6c84aa19994b3d69e15d claims it is actually there... maybe something else is needed for your card....
I haven' t tried it myself yet. I'll wait for the stable release just to be sure... till then, i'll stick with this patch solution...

[venky80 (venky80)]

Hi Mahdi,
Is it possible for you to tell the procedure you took to patch your kernel?
I mean it will be helpful for us noobs.
Also what laptop model do you own?

I can confirm that the problem also effects the Acer Aspire 4720 w/ Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) and the ALC268. It's making me only a little crazy though, so I'm going to wait until the kernel revisions catch up.

Thanks for everyone's hard work.

[Mahdi (mahdi-hates-spam)]

I just followed that howto you wrote. Not using anything official...
just googled and found that info, so i'll stick with the workaround till we got official support ;)

I'm using a Toshiba Satellite A205-S4797.

By the way, with those patched files you provided attached we get sound, but no recording and when a headphone is plugged, there's still sound on the internal speakers.... :(

[]z!

[Romano Giannetti (romano-giannetti)]

Well, I think that the right thing to do is trying to follow what's happening on the alsa bugreport:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104
with the realtek17 patch on top of a recent kernel I have sound, muting and recording, although with problems (headphone level is quite low, recording qualty is barely acceptable, etc).

[Romano Giannetti (romano-giannetti)]

I have a toshiba U305-S5077, which a hda_intel chip that identifies itself as
0x1179:0xff50.
This morning I tried to separate the toshiba parts of the patch from pshou and obtained, as first try, the attached patch. With this patch on top of a current kernel (which, by the way, I need to have suspend to ram working) the sound works, recording included, but:

1) there is not automute when you plug the headphones (will try next),
2) the front mic level is TOO low
3) the recording quality is quite bad.

For the point 2), in Vista there is a "front mic boost" slider, which is missed in Linux.
For the point 3), my guess is that the offset (dc value, continuos level, I do not know how to call it) is the main culprit. You can see it in action here:

https://bugtrack.alsa-project.org/alsa-bug/file_download.php?file_id=2129&type=bug

That too is not present in Vista. This is a bad problem, I think, much more difficult to resolve. It is as if the card tries to output only positive values and that this is not took into account in the software, but trying to check it is I think too difficult to me.

[Romano Giannetti (romano-giannetti)]

Another comment: after a fresh reboot the recording does not work. You have to select "Front Mic" and then "Mic again", and disable/reenable capture, then it works.

Hmmm, something is quite fishy here.

[venky80 (venky80)]

for the new kernel in gutsy nothing works for me I have A205-S4577 can
anyone post all the patches which they used, if they were able to get the
sound working for the above mentioned laptop model with latest gutsy kernel.
Thanks,
Venky

It works for me with my posted patch; I am attaching now the complete file, try it (recompiling alsa-driver as ever). And remember, you have to disable/enable again the microphone in order to have it working.

Hi,

just an update: using the last HG driver on top of a 2.6.23 rc kernel the sound system of my toshiba A305 works ok (loading the module with model=toshiba parameter), including microphone, external/internal.

See: http://lkml.org/lkml/2007/9/7/25

[venky80 (venky80)]

isnt gutsy still using 2.6.22-10 ??
has anybody gotten their sound working with above version kernel and
a205-s4577 model laptop?

Sound works on a Dell Inspiron 1420N with yesterday's daily build. I've been told it uses this chip at Bug #119255.

[Mahdi (mahdi-hates-spam)]

Romano,

did u try the latest gutsy kernel and alsa without patches? Seems like the latest alsa-git already works fine with alc268 and model=toshiba... just dont know if it is already included on the latest kernel *without* patching alsa... that would b really great news, since we got a kernel upgrade today :)

[Romano Giannetti (romano-giannetti)]

Hi,

I didn't try gutsy kernel (2.6.22) because I need a 2.6.23 for other things (namely, suspend to ram) to work. And you know, s2ram *must* work, otherwise you loose 90% of the functionality of a laptop. But I suppose it should work. If I have a bit of time (I have two very bad weeks ahead) will try.
Mahdi, have you tried the problem with offset in recording I commented in
http://lkml.org/lkml/2007/9/10/17 ? Just try to start recording with audacity and see if changed mic level you have a continuos value varying with it... and saturating the input at high levels.

[venky80 (venky80)]

Hi Brain,
hich daily build are you talking about and where can I find it?
Thanks,
Venky

[Mahdi (mahdi-hates-spam)]

Hmmm... s2ram works on 2.6.23 on toshiba A20* laptops? Cant wait to get this one on gutsy.... that still bugs me... any patches neede?

Tried that but got the same behaviour described... =/ recording isnt as important as playing though... it works, but very low and with that offset prob you said.

[Romano Giannetti (romano-giannetti)]

Venky:

The HG snapshot is at ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver

Mahdi:
2.6.23-rc5 do suspend to ram perfectly with s2ram -f -p -m, no patches needed. Someone told me that the failure with previous kernels is SATA-related, but I lost the reference.

Recording is quite important if you use your laptop to work together with other people with ekiga or skype or whatever voip...

[venky80 (venky80)]

Romano,
I downloade the HG snapsot and tried installing the lib, utils firmware and
driver

[Brian Mount (bvmou)]

I think the last error messages relate to some japanese gettext tools. Install the package "ja-trans". BTW, I have built the Aug 31 RC1 from alsaproject.org and it works fine under Ubuntu 7.04, resolving the headphone issue.

[Romano Giannetti (romano-giannetti)]

Venky,

I had the same problem; I just recompiled the driver and installed it. Lib, utils etc are at 1.0.14.

[Mahdi (mahdi-hates-spam)]

Romano,
I noticed you got the modem working with slmodemd. What alsa module did u use? R u running i386 or amd64?
I'll try alsa 1.0.15rc1 tonight (it says it includes alc268 support)... see if there r any improvements. Hopefully gutsy will b released with working alc268 and kernel 2.6.23 and we'll get s2ram and sound working out-of-the-box :)

[Romano Giannetti (romano-giannetti)]

Modem seems to work, but it simply responds to AT commands, on connection it fails with NO CARRIER.

Do not try releases... I think it's better to try the current driver --- the tight interdependencies between driver, lib and utils should be a thing of the past, Linus himself ruled that out sometime ago. And the current 2.6.23-rc6 claims al268 support,but without toshiba quirks, so that it will not work for us.

By the way, I'm running i386 SMP.

[venky80 (venky80)]

hi Romano,
I tried compiling lib utils firmware from alsa 1.0.14 and driver from
snapshot .Everything went well except after restart when i run the command
alsamixer i get
alsamixer: function snd_ctl_open failed for default: No such device
are you using some patch?

yet with latest kernel?

[Mahdi (mahdi-hates-spam)]

Hi,
tried 1.0.15rc1 and everything worked fine. Quality is much better, specially for recording. No patches needed.

I know that the drivers should be enough, but i'm just trying the whole thing for kicks. It's not all that difficult to make install libs, firmware, utils and drivers if i have to make install drivers... and that somehow less buggy, since testing is all done on releases...

Romano, what do you mean by "toshiba quirks"? Do you think 2.6.23 final will support alc268 out of the box?

[Romano Giannetti (romano-giannetti)]

Venky:

no I am not using any patch. No problem till now... (well, minus the offset value of mic input).

Mahdi:

Unfortunately what I understand from this interchange of messages on lkml: http://lkml.org/lkml/2007/9/5/166 is that the changes (acer and toshiba quirks went in after 1.0.14 both) are considered too risky for mainline 2.6.23. So I suppose that our sound will not be supported in mainline till 2.6.24. I tried to mildly object this, but you know, developers have (correctly) the last word.

[Jose Munoz (jlmunoz-pucp)]

Hi all:
I found a simple solution to audio problems:
Use the realtek-audiopack 4.06b
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

I am still testing, but now amarok, xmms, etc. are working perfectly.

Regards.

[venky80 (venky80)]

Hi Jose,
Can you please mention what laptop model and what version of Ubuntu are you
running? (kernel version)

[ashley (ashleys)]

I just got everything working using the Realtek drivers as Jose mentioned.

I followed the steps just as they are in the Readme.txt bundled with the drivers. Here is what I did.

1) sudo apt-get install build-essential ncurses-dev gettext linux-headers-`uname -r`
2) Download the drivers and extract them
3) cd into the extracted directory
4) tar xjf alsa-driver-rt20070820.tar.bz2
5) cd alsa-driver-rt20070820
6) ./configure
7) make
8) sudo make install
9) sudo ./snddevices
10) sudo vi /etc/modprobe.d/alsa-base (pasted a few lines into the bottom of this file see *****'s below)
11) reboot your machine
12) You should hear the ubuntu drums when it starts back up.
13) Open the gnome mixer ()volume control icon in the panel).
14) Tick PCM, Front, Headphone, capture and input source (no I don't know if it has to be this ... I do know this worked though)
15) Under the recording tab make sure it is not muted and under options tab make sure input source is mic.
DONE.
I was able to play mp3s, and with headset plugged into the front I had muted speakers and headset worked on skype test call. That's enough functionality for me.

*****
Put the below into the bottom of your /etc/modprobe.d/alsa-base file as described in step 10 above(from the Readme.txt). I used snd-hda-intel in place of snd-xxxx. The readme lists a few options you may have to try instead.

Hi, I use the realtek-audiopack 4.06b

http://www.realtek.com.tw/downloads/downloadsView.aspxLangid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

In Ubuntu Feisty using the kernel

root@macafe:/home/felipe/Desktop# uname -r
2.6.20-16-generic

Note: In 2.6.22-11 is not working

My sound it's working, but the suport to Headphone are not perfect...

Important: I had install some depends to compile alsa.

Toshiba A205-4797

[venky80 (venky80)]

Oh so ashley's method is not working for 2.6.22-11?

For me, using 2.6.23rc6 kernel from kernel.org fixed my sound. I have an
ALC880.

ashley's post fixed my sound... But now color is totally screwed up in all my media players.

[venky80 (venky80)]

please mention the kernel and laptop model when any patch has worked for
you.

I have tried every patch on my a205-s4577 (kernel 2.6.22-11) nothing has
worked yet.

Satellite A205-S4587 w/kernel 2.6.22.11.13 (I think). Video quality is restored after updates in Gutsy.

[venky80 (venky80)]

Hi,
Has anyone been able to get their sound working on A205-S4577 laptop with
Gutsy (kernel 2.6.22-12-generic). I know many people have got it working on
other models or other kernel versions. I have tried all their methods and it
has failed.
Please let me know if anyone of you has a same model of laptop, and has got
the sound working.
Thanks,
Venky

Same here, tried all patch that also worked previously with Feisty and alsa 1.0.14a but now they don't work, even recompiling all alsa-driver.
Haven't tried realtek package.

What is happening? Why new kernel doesn't work? Anyone has a solution?

[Marco Cimmino (cimmo)]

Guys,
 I just installed Arch Linux in my toshiba a205-s4577 and I was able

Venky,

I tried it, and yes, with alsa 1.0.15rc3 it sort of works, but with the problems I signalled before: mic level is low, and it's plagued by a very high offset. Have you tried to see if it's the case for you? Is very easily seen with audacity. See my reports on the alsa bug entry:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104

Thanks!

[venky80 (venky80)]

I will check on it but, I was able to do a decent voice chat on skype but
the front mic boost level was set at maximum( there was no front mic level).
Also for the boost level there was only 3 levels of setting.
Will post my findings. meanwhile in I tried alsa 1.0.15rc3 in ubuntu gutsy
and it didn't work.
Thanks,
Venky

[Mahdi (mahdi-hates-spam)]

alsa 1.0.15rc3 works fine for me. Front mic is a little low, but I can have decent skype chats with volume set to max.
i'm running gutsy on a toshiba satellite a205-s4797.

[Marco Cimmino (cimmo)]

Mahdi really 1.0.15rc3 and Gutsy?
I've tried but without success, is there a special procedure to follow? some files to edit?

please give more details.

thanx

[Mahdi (mahdi-hates-spam)]

Yep.
Nothing special.
Just aptitude install the latest kernel headers, build essential and ncurses-dev (so you can compile everything), download alsa-libs, alsa-utils, alsa-firmware and alsa drivers from www.alsa-project.org; and "./configure; make; make install" everything on the following order (thats imporant): libs -> utils -> firmware -> drivers.
Reboot, umute and set all volumes with alsamixer and there you go. :)
if it doesnt work, try adding "options snd-hda-intel model=toshiba probe_mask=1" (or model=acer, if you got an acer laptop) to /etc/modprobe.d/sound (and rebooting again).

[Romano Giannetti (romano-giannetti)]

venky80:

I'm confused... you said it worked in Arch Linux (which kernel) with the latest Alsa drivers (which I suppose are 1.0.15rc3) and that it didn't work in ubuntu with the same latest alsa divers?

This change was reverted on the very next upload. Are you sure your
sound still doesn't work? We can't just update all of alsa at this
point, so trying things like model=3stack and model=5stack for your card
using our stock driver would be the best way to get this resolved.

[Romano Giannetti (romano-giannetti)]

Ben,

I am willing to help to test this. I have a similar laptop to the one of venky (toshiba U305),
vendor-id 0x1179, 0xff50, and I am running Feisty with a vanilla (Linus') 2.6.23-rc9 kernel, plus I have tried various alsa drivers.
I want to be sure to do the right thing, so...

 * I recompile the drivers (./configure --with-cards=hda-intel)

 * I have alsa lib 1.0.14 installed; someone on the lkml list told me that's ok to test reinstalling just the kernel modules, is it true?

 * My sound sort-of-work with 1.0.15-rcX, last hg snapshot (20071002), and the last realtek driver (4.06c), autodetected as model=toshiba. The problem is with the very lousy quality of recording, given in my opinion for the persistent problem of the huge dc offset in input (there are snaphsot and plenty of details on the alsa-bug 3104), which is not resolved.

 * I tried to test model=3stack and model=acer with the procedure:
    - Install the new driver (as above)
    - /etc/init.d alsasound stop (a couple of times, first one fails)
    - modify /etc/modprobe.d/alsa-base adding model=... to the options snd-hda-intel line
    - restart alsa by modprobe snd-hda-intel (and resetting and setting all the mixer values).

Till now, no drivers has the sufficient quality in microphone input to make a Skype call possible.
If I can help test patches, please tell me. Should I try 5stack? Is the aforemention procedure correct for testing?

Romano

[Tim Gardner (timg-tpi)]

One thing a lot of people miss when updating with ALSA is to remove the original snd-hda-intel.ko.

cd /lib/modules
sudo tar -czf `uname -r`.tgz `uname -r`
sudo rm -f `uname -r`/ubuntu/media/snd-hda-intel/snd-hda-intel.ko
cd ~/alsa-driver-1.0.15rc3
./configure; make && sudo make install

You can always recover by restoring your saved modules:

cd /lib/modules
sudo rm -rf `uname -r`
sudo tar -xzf `uname -r`.tgz

[Marco Cimmino (cimmo)]

yes exactly for unknown reason snd-hda-intel is under a different directory than other audio modules.

Anyway I think Ben want to say that we have to test the ubuntu module that is just present without installing nothing else and reporting which combination of model=<something> is working for us.

[Mahdi (mahdi-hates-spam)]

Well,
No combination works for me on gutsy without installing anything.
I get sound only installing alsa 1.0.15rcX, and not only the drivers, but libs, utils and firmware too.

[Marco Cimmino (cimmo)]

also here with normal gutsy sound doesn't work at all, I've tried all possibilities: [3stack,5stack,acer,toshiba,auto] nothing worked

now I will try other possibilities and I will report here

[Fred (frederic-lespez)]

I have an Acer TravelMate 6292 with a Realtek ALC268.

For gutsy, the snd_hda_intel module is now in the lum package (ie. linux-ubuntu-modules-2.6.22 package).

So as suggested, I rebuild the gutsy lum package after patching it with the realtek 17 patch available here:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104

After installing the newly package and adding the following line in /etc/modprobe.d/alsa-base:
options snd-hda-intel model=acer

Note: You can specify one of the following model : acer, toshiba, 3stack or auto

After that everything almost works !!!
 - Internal speaker works
 - Headphones works and internal speakers are automuted when plugged
 - External speaker works and internal speakers are automuted when plugged
 - Internal mic doesn't seem to work...
 - External mic untested.

The deb attached is the my rebuild of the lum package for gutsy.

Shoudn't we reaffect this bug to the lum package ?

[Marco Cimmino (cimmo)]

Fred thanx a lot! Your package works!
Hope patches will be included soon in the ubuntu module, I have added the project, please add them prior to Gutsy release and kernel freeze :)

with the one provided in patch 17. That's all.

thanx fred.

Ubuntu audio team is it possible to add the file before kernel freeze? It is really needed to make a lot of soundcards work here.

someone else that try Fred package and can confirm?

[Mahdi (mahdi-hates-spam)]

Romano,
you said smth about using 2.6.23rcX so you could have s2ram.
What happens if you use 2.6.22? It suspends but do not resume (or resumes to a blank screen)?
Are you running compiz-fusion? Is your laptop a A205-S4577? What video driver are you using (intel or i810)? Where did you read about this 2.6.23 fixing a sata issue that messed resume? Is there a bug open for that?

[Tim Gardner (timg-tpi)]

This update to patch_realtek.c diverges too far from ALSA 1.0.14 which is the base version originally included in linux-ubuntu-modules for snd-hda-intel support. I am concerned about regressions. However, I am working on a Gutsy backports package that will include all current ALSA drivers. It ought to make it in time for the official Gutsy release.

[Fred (frederic-lespez)]

Tim : I agree with you, it is a big patch against alsa 1.0.14.
If alsa 1.0.15 can make it for Gutsy release, that 's really great ! Thanks a lot.
I just hope that Gutsy will work out of the box with this kind of card.

I'm willing to test your packages. Feel free to ask.

[Ben (ben-speakmon)]

Tim: I agree as well. I have (mostly) working sound with ALSA 1.0.15rc3, and I'm happy to test the backports package when it's ready.

It suspends (at least, it seems to suspend ok: the laptop goes off and
the led blinks as expected). On resume, the hdd light stays put and
nothing happens. Alt-SysRq magic keys don't work, and I have to do a
very hard reset (power button during ten seconds) to reboot. Sometime I
have to repeat the hard reset. Very messy status.

My laptop is a U305-S5077. I have a page for it here:
https://www.dea.icai.upcomillas.es/romano/pmwiki/pmwiki.php/Main/ToshibaU305
I use beryl (apt-get install beryl emerald, from feisty, works ok).
Driver is i810, I need the 915resolution hack to make it run.

For the suspend problem, I thought it was this, but the proposed patch
didn't work for me:

Here is a patch against latest lum package to add support for RealTek ALC268.

This time I have extracted from the realtek17 patch _only_ the parts concerning
the RealTek ALC268.
This way regression are avoided (since alsa 1.0.14 doesn't support ALC268 at all)
So the risk of applying it is also minimum IMHO.

I have posted a link to rebuilded lum packages here :
https://wiki.ubuntu.com/LaptopTestingTeam/AcerTravelmate6292

Tim : Could you consider applying it in case alsa 1.0.15 is not ready in time
for Gutsy release ?

[Marco Cimmino (cimmo)]

Fred thanx again and all my support to this patch to reach Gutsy!

[Fred (frederic-lespez)]

For the record, there are two other bugs in alsa 1.0.14 bugtracker with patches for Realtek ALC268 :
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3268
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3332

I'll try to see if my last patch can be improved with those.

[Fred (frederic-lespez)]

Here is an updated patch against latest lum package to add support for RealTek ALC268.

I have improved the patch by adding bits missing bits from the other alsa bugs (see my previous comment). I have also extracted some bits from alsa 1.0.15rc3.
I have taken care to only add ALC268 support without touching anything else.

This patch seems a little better : sound volume is higher. I did not test mics or suspend/resume.

I really hope to see this issue fixed before Gutsy release !

I have posted a link to rebuilded lum packages here :

[Mahdi (mahdi-hates-spam)]

Kernel 2.6.23 is out and claims to have included realtek alc268 support.
Anybody who tested and confirmed that (sound working without patches and no alsa recompilation)?
It might be a better solution to create new kernel pkgs instead of new alsa packages, since 2.6.23 fixes lots of important bugs, mostly related to sata and suspend/resume.

AFAIK it has only the basic support that was in alsa 1.0.14 which, at
least for me, does not work. If you see at the famous patch_realtek.c
file:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=sound/pci/hda/patch_realtek.c;h=9a47eec5a27bb27a7f24c00d7ab9189cb34ac98c;hb=bbf25010f1a6b761914430f5fca081ec8c7accd1
there is only ALC268_3STACK and _AUTO models, nothing about _TOSHIBA od

I have sound working with 2.6.23 kernel plus the patch here:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.23-rc8/2.6.23-rc8-mm2/broken-out/git-alsa.patch
that I think will be pushed to 2.6.24 at an early stage of development.

Mahdi:
kernel 2.6.23 will never reach Gutsy, because it's only 6 days distance for final.
That kernel and probably a newer one will be in Gutsy+1.

So all that we can ask for now is if Fred's patch will reach Gutsy.

[Fred (frederic-lespez)]

Good news !!
Alsa will be updated : See this comment in bug #131133
https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.22/+bug/131133/comments/154

I think this backport will include alsa 1.0.15 drivers so this bug will soon be fixed :-)

Romano : The patch I proposed include ALC268 support for model toshiba et acer.

[Fred (frederic-lespez)]

Here is an updated patch against latest lum package to add support for RealTek ALC268.

I will soon post a link to rebuilded lum packages here :

I have a toshiba A205-4777. I using method C from https://wiki.ubuntu.com/Gutsy_Intel_HD_Audio_Controller and almost everything works.

The internal and front mics work and the headphone sense kinda works. The sound is muted from the speakers when I insert the headphones, but if I adjust the volumn from the front knob the speakers get unmuted.

Apart from that everything is great and all is right with the world.

[Adrian (ruewan)]

I used method b not c

I'm running latest gutsy amd64 on this very notebook (Toshiba Satellite A205-S4797) and everything works like a charm...
only needed to recompile alsa-drivers 1.0.15rcX from sources (everything else is ubuntu default).

how you are using gutsy amd64 with Core 2 Duo ?

Sorry, I can't understand ...

why are you all reinstalling alsa?
If Fred said that the module is now in backports you have just to
install: linux-backports-modules
without compiling anything.

Fred do you confirm?

[Mahdi (mahdi-hates-spam)]

amd64 is meant to be used with any 64bit processors, such as Core 2 Duo (EMT64), not only amd ones (such as Turion).

[Mahdi (mahdi-hates-spam)]

I did not try that yet. I just had it working some time before the patch was out :)
since it works I rather not mess around with it too much lol

Sure. Everything works fine for me. I have to install some ia32 libs and apps for some stuff but, other than that, no problems at all. All my hardware (except sound and modem) work out of the box with good performance.
Never tried i386 on my x64 cpus though.

the intel-hda works fine for sound (with latest alsa, because, of course, alc268) and detects the modem right too (for use with slmodem-daemon), but i couldnt make it respond to any commands... =/ anyone got that working with a intel-hda rtl alc268 card?

Just tried the latest gutsy kernel on amd64 on a Toshiba Satellite A205-S4797 with the latest gutsy backport modules.
Both sound playback and recording work fine. Recording quality is quite poor though. =/ Recompiling alsa-drivers 1.0.15rcX from sources seems to provide better recording quality.

[Fred (frederic-lespez)]

The linux backport modules work on a Acer TavelMate 6292.
Adding manually the following line in /etc/modprobe.d/alsa-base is still needed though :
options snd-hda-intel model=acer

[Mio (m10)]

I've got an Acer Aspire 5710z with 2.6.20-16 (32 bit) kernel with an HDA intel audio card with a Realteck ID 268.
I succesfully got sound working compiling the 1.0.15rc3 ALSA driver but that broke my Linuxant driver (v. 7.68 hsf) for my Conexant HDA modem reinstalling both didn't work, uninstalling it again it works (not the modem).
I made a post in ubuntuforums too: http://ubuntuforums.org/showthread.php?p=3542847
Should I file a new bug?

[Marco Cimmino (cimmo)]

Mio:
I have successfully made working the modem with sl-modem daemon and module without hsf, so take a look to it
If it has a motorola chip inside then leave hsf alone ;)

with reinstalling both didn't work I meant: reinstalling(the modem driver) did break both the sound and the modem.

ah, finally got the sound working "out of tha Box"

If you got an Compal Laptop, use "options snd-hda-intel model=toshiba"

got sound working on my acer extensa 5220 - realtek alc268
headphone plug now works and automutes internal speaker. i also have now all necessary mixer controls.

needed to install the "linux-backports-modules-generic" package and adding manually the following line at the end of /etc/modprobe.d/alsa-base :
options snd-hda-intel model=acer

i think sound is not as loud as in windows xp but loud enough for me.

thanks for help... i think that new ubuntu users shall be told that they have to install the package and add the line if they own the realtek 268 chipset

yes it didn't work. it works fine now. I had various versions of the same modules in the /lib/modules. I deleted /lib/modules and reinstalled linux-image-generic. then I compiled the latest alsa 1.0.15.
now it works. It loads snd-atiixp. snd-hda-intel is not loaded

toshiba a210-15Y

[tudor (tudor-gmx)]

installing sudo apt-get install linux-backports-modules-2.6.22-14-generic works too. it is important to delete the previous versions of the driver intel-hda and atiixp before installing the backports

[Marco Cimmino (cimmo)]

probably you installed to many modules that made conflicts, but in a clean system it's not relevant.

[Felipe Cardoso Martins (macafe)]

I'm running Gutsy (64 bits) with backports, but yet my sound doesn't working..

In saturday I will try reinstall the system with 32 bits and do
everything of I already see.

Anyone recommend me do something first in clean system ?

It seems that the external mic can work with alsa 1.0.15 (the linux-backports-modules contain only alsa 1.0.15rc3 AFAIK).

I installed linux-backports-modules on my zepto znote 6625WD (using an ALC268 sound chip) and sound _is_ working, but when I plug in my external speakers my internal speakers are not muted.
I also observed that unlike in windows (be it XP or Vista), here in Ubuntu it _does_ matter where I plug in my external speaker jack, no "autoconfiguration" there (or jack sensing as I believe it is also called).
I haven't tried using the microphone.

[Eskild Hustvedt (zerodogg)]

Sound works with linux-backports-modules, but no automuting of internal speakers when external speakers are plugged in (no way to mute the internal ones in fact).

but there is no post I can find getting the mic going. There are lots of posts but the sound card neither supports mic internal nor external. This seems to be a driver problem. This laptop is sold in India with linux preinstalled but not with Ubuntu.
I had no chance to test the Linux preinstalled as shops delete it and replace it with windows.

As per the comments from Felipe Cardoso Martins , a Toshiba Satellite Pro A200-PSAF 1A-001001

apt-get install linux-backports-modules-generic

[Jean-Paul (jeanpaul145)]

I don't know about mic, but after changing the line "options snd-hda-intel model=acer" to "options snd-hda-intel model=toshiba" in /etc/modprobe.d/alsa-base on my zepto znote 6625WD (it has an ALC268 sound chip) the internal speakers *do* mute when plugging in a headset in at the right jack. jack sensing does not work.
Additionally, when I change the volume with my "volume up button", the internal speakers unmute. Using the "volume down button" does not unmute the internal speakers.
This last part can (I think) be fixed by changing which slider the volume buttons control (even the "volume down button" to keep some conformity/symmetry :p) - Is there any way to do that without some hardcore coding? Thank you in advance.

Update with Hardy Alpha 5:

[Romano Giannetti (romano-giannetti)]

Hi,

My Toshiba U305 has really better behaviour with last released alsa (1.0.16), although still there is a lot of noise and offset on recording and a quite low volume level on playback compared to the Other OS.

By the way, the referenced bug:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3637 is (Takashi said it) relevant just to acer model.
There are more open bugs on alsa about this issue:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3659
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104

I will try to report something more on the most toshiba specific one.

[Leann Ogasawara (leannogasawara)]

Hi All,

Just doing some clean up to this report. The original bug was that there currently wasn't support for the Realtek ALC268 codec found in the Toshiba A205-S4577. This seems to be resolved via the linux-backports-modules-2.6.22 package which contained an updated version of ALSA so I'm going to close this report. If you are now experiencing new issues with the mic or sound quality, please open a new bug report. Also be sure to test against the latest Hardy Alpah release. It is helpful to the development teams if bug reports target one specific issue against a specific set of hardware. Thanks.

With my U305 the mics sort-of-works with alsa-driver 1.0.16 on top of
Gusty, or with a 2.6.25 kernel. Sort-of means that I had to find the
magic combination: mic boost at about 1/3, capture level at about 2/3,
digital capture (a new control with 1.0.16) at about 1/3. Other
combinations make the mic too low, too noisy or to distorted.

Takashi has been out quite a long time, but now he's back. I'm confident
that now that he's back things will start again to roll.

My sound also started to work now which is pure joy. Thanks to everyone who contributed to making this happen!

As pointed out by others, the microphone doesn't work though. Here is the strangest part though:
If I install "recordmydesktop" then the mic works but it records with extremely low volume. With the usual "sound recorder" utility app all I get is aggressive snapping or pounding sounds (reminds me of some kind of motor or something). These strange snapping sounds are also not related to how or what I say when I'm recording, the snapping sounds that's actually being recorded into the audio file are regular in pace and volume. Microphone also doesn't work in Skype on Linux. In Vista on the same machine the mic works in all apps. I have tried googling for hours on various configurations inside alsamixer etc but nothing worked. I've tried unmuting/muting various channels like "mic boost", "front boost" etc and I've tried all kinds of input source settings but I simply could not get the mic to work in ubuntu inside any application except for the strange and magic "recordmydesktop" application. Finally, one more curious detail is that I tried to boot Fedora Core 9 Preview on this same machine and there the mic didn't work either (which is not that suprising given that they have the same ALSA version, they have pulse audio etc) but for some reason I can actually get the mic to work using the F9 preview live CD by deploying the usual tricks (messing around with settings in alsamixer etc). I also noted that if I turn up the "mic boost" to maximum in F9 I hear those strange snapping/pounding sounds again but much weaker.

Getting high quality microphone support to work would be a great improvement though, mostly because of Skype.

I own a Toshiba satellite A210-158 and iI have excatly the same output as mnemo.

Sound works good, audio jack finally works too. However, with microphone there's no way. I've been googling for long hours too but nothing. When I try i get those annoying sounds described by mnemo.

No mic on skype neither.

Last thing I haven't tried it's mic jack. But built-in mic doesn't seem to work at all.

There is 1 thing that still bugs me: whenever the audio system is initialized (like at bootup) and I have external speakers plugged in, I have to unplug them and plug them back in after audio has initialized. If I don't, the external speakers aren't used at all, as if they were never plugged in at all. Since I have external speakers plugged in whenever I am home, and have earpieces plugged in when I am not, this is a real problem.

For informational purposes: I have a zepto Znote 6625WD which has a Realtek ALC268 audio chip.

i have a Compal IFL90 laptop and sound didnt work at all since Ubuntu Gutsy. However the mic still does not work in Hardy. I tried the live cd of Alpha 4 of Intrepid a few days ago and i increased the mic boost and it finally worked with a headset. The internal mic still ain't working. So there is some progress but there seems much to be done.
Would be interesting if the mic works for some of you guys with Intrepid Alpha 4 and a headset.

[JClift (jclift26)]

I have a dell vostro 1310 which has no sound/ mic at all unless workaround applied in hardy (which makes sound not 100%). Need to check if still works in new kernel. Has realtek alc268 chip.

when clicking on vol control get told can't find gstreamer plugins. Driver needs to be compiled....

[JClift (jclift26)]

Can confirm in latest kernel had to compile drivers from realtek website andadd also digital input sources to ALSA in order for all sound to work- this picks up headphone jack and speakers. Mic as yet untested, but think it works from headphone source and onboard..
I followed these instructions and used 5.07 drivers from realtek site.

Hope this helps

The good news :
The main issue remaining with Realtek ALC268 was that mics doesn't work.
Alsa 1.0.18a contains a fix for that:
http://git.alsa-project.org/?p=alsa-kmirror.git;a=commit;h=2cc442715c45c88016c3c1c68e8828683d1b186a
This add a new model acer-dmic for all laptops that have digital mics.

The bad news :
Jaunty doesn't have alsa 1.0.18a :-(
It is currently stuck with alsa 1.0.18.
A bug report has been opened to update alsa :
https://bugs.launchpad.net/ubuntu/+bug/304068

Good news for laptops with a Realtek ALC268 codec and an internal digital mic (like Acer TravelMate 6292) : Now it works in Karmic (thanks to Alsa 1.0.20).
But you need to modify You need to replace the following line in /etc/modprobe.d/alsa-base:
options snd-hda-intel power_save=10
with:
options snd-hda-intel power_save=10 model=acer-dmic
And then reboot (or reload the snd-hda-module).
After that, internal mics works.
Record level is a bit low but is works :-)

hi
realtek has a linux driver - it solved my 6 channel audio with a alc883 chip
you can download it from here:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
or:
reltek>download>high definition audio driver

i'll attach the readme for the driver, basically sayes that it supports alc268
