[regression]snd-hda-intel sound input does not work at all with Conexant CX20549 (Venice) chips

[sibidiba]

On Lenovo R61i the sound input does not work at all.

I am using snd-hda-intel as the driver for

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

The built in microphone does not work at all, it always produces silence. Moreover the mixer settings of the silent internal and the (buggy) external microphone are interchanged.

If I try to use any external microphone the sound is utterly jerky, unusable.
The interesting thing is, that if I turn on and unmute the external mic (with the slider of the internal mic) the echoed sound in the speakers is clear, just the recording result is broken.

Try to record with any app. Some of them produce just silence or just crash (kmix). If there is some sound (noise), it is unrecognisable (skype test call).

[sibidiba (sibidiba)]

Lot of people experience problems with various codecs using snd-hda-intel.

I have set up this page to summarize the problems:
https://wiki.ubuntu.com/SndHdaIntelSoundProblems

Bugs are only related if they are for the same module and codec/chipset:

cat /proc/asound/card*/codec\#*|grep -i codec

[EAB (adair-boder)]

I too have the Thinkpad R61 and the mic is not working at all. Very frustrating!

[EAB (adair-boder)]

Will this issue be fixed in Intrepid?

[sibidiba (sibidiba)]

@Zeth: right now, the situation is the same for Interpid.

[sibidiba (sibidiba)]

I also tried SuSE and Knoppix. All the same. It's a kernel bug.

[EAB (adair-boder)]

So where does that leave us? Is the issue being worked on? Sorry for asking so many questions ... I just can't believe I found myself buying a new laptop which cannot utilize an internal or external mic ...! It's like a major step back for me since I use Skype and VOIP so much...

[sibidiba (sibidiba)]

Just the same for me. I don't now anyone working on this.

[skflyfish (jpeasley)]

Also a Thinkpad R61 and the internal microphone doesn't work, despite trying every I could find.

[sibidiba (sibidiba)]

@sklyfish

Which codec chip do you have? Run this command as root to see:

cat /proc/asound/card*/codec\#*|grep -i codec

And possibly add your findings to https://wiki.ubuntu.com/SndHdaIntelSoundProblems .

[skflyfish (jpeasley)]

jay@jay-laptop:~$ cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Conexant CX20549 (Venice)
jay@jay-laptop:~$

thanx!

[EAB (adair-boder)]

So what does it usually take for these issues to start getting some attention from the ppl who have the expertise to fix it?

[sibidiba (sibidiba)]

I am actually a programmer, but without real experience in kernel-hacking, and I also do not know how the ALSA subsystem works in general. Would probably take longer to see through this then somebody else - with experience in this area - fixing it in an afternoon. But I would help if anyone would just provide some idea where to start.
But I also really do not understand why this issue does not receive any attention. I guess the sound input just does not work in Ubuntu on at least 50% of laptops used today!

[EAB (adair-boder)]

This leaves me to wonder if most of us Ubuntu users are doomed to either only using older, better supported hardware .... or new hardware which is not fully supported and therefore does not deliver expected results!?
Will Ubuntu (Linux) ever be up-to-date? .. It's probably a "bad" question to be asking here ... ;)

[EAB (adair-boder)]

btw .. would a USB mic work?

[skflyfish (jpeasley)]

I have a Plantronics USB headset and the mic from it would not work either.

I am a programmer also, but not on a Linux/Unix platform, so the learning curve would be large for this someone over 55. Despite this drawback I am really happy with Ubuntu Linux and its stability and speed. And it's free price tag. After suffering for 25 years with M$ crap, I will never go back.

[skflyfish (jpeasley)]

Sound output just took a turn for the worse with 8.10. Now the internal speakers are way over modulated and scratchy even at lower volumes. Let all the way up it is deafening. If I try to record a message with Sound Recorder to test the mic, the elapsed time clock is way fast and eventually locks the program up.

Considering that I could barely hear the internal speakers under Vista it is an improvement. Just too much of a good thing. The speaker output under 8.04 was perfect. Just no input from the internal mic.

Jay

[skflyfish (jpeasley)]

The sound issues are related to the new Linux kernal. When I drop back to 2.6.24.21 then the sound output is fine again.

[jhoechtl (johann-hoechtl)]

Another voice to get it fixed:

This is a HP Pavilion dv6782eg (KN070EA)

I am an Kubuntu Intrepdi, uname -a:

Linux deneb 2.6.27-7-generic #1 SMP Thu Oct 30 04:12:22 UTC 2008 x86_64 GNU/Linux

lspci | grep Audio

Output of
cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Conexant CX20561 (Hermosa)

I experience the same problem: Whatever combination of input / output settings (mute/unmute, 0%, 50%, 100% gain, ...) the internal microphone is mute / not working. Tried different sound servers.

BEWARE to other lurkers / readers: Some mentioned, that certain bios have a switch to disable the int. mic. Mine hasen't, so this is not the issue.

Johann

[sibidiba (sibidiba)]

I added regression to the description, as I see the problem for some people to disappear when using really old modules. (Gutsy and before). Internal mic stil doesn't work, but external one does.

I honestly encourage the ubuntu auio team to at least make a comment why snd-hda-intel is not working for so many people.

[EAB (adair-boder)]

I upgraded to Intrepid and still have no mic, internal or external, working. The Sound Recorder seems to be broken as well ... when I press the record button is starts recording at super fast speeds ... like in a few seconds its already over 1 hour ... and then it just crashes.

[EAB (adair-boder)]

skflyfish, I had a a problem with the sound playback as well until I lowered PCM to about halfway ... and then it was great!

[skflyfish (jpeasley)]

Hi Zeth,

With the PCM at about 58% it is useable but still a bit scratchy. I usually boot back to 2.6.24.21 for this and other oddities that are happening.

btw:
lspci | grep Audio

[carnage (carnagewashere)]

same problems for me now with 8.10 and before with 8.04.
internal mic has never worked although if i really yell into it i can hear it just faintly in the playback from sound recorder with pulseaudio running. also have the interesting and annoying bug where i unmute the mic (the 'toggle audio recording from..." button) in the volume control under the recording tab, close volume control, open it again and it's magically muted again.

haven't tried with an external mic

[EAB (adair-boder)]

Why is the importance of this bug still "Undecided"?
What does it take for it to become important?

[Leann Ogasawara (leannogasawara)]

During the Intrepid development cycle the linux-ubuntu-modules package was merged with the linux kernel package. So it unfortunately seems this bug may have been getting overlooked. For now I'm going to retarget this bug to the actively developed linux kernel package.

For anyone still having issues, if you could please test the Intrepid Ibex 8.10 final release that came out last month that would be great. You should be able to test using a LiveCD. If you still experience issues please download the alsa-info.sh script at http://alsa-project.org/alsa-info.sh and attach the resulting file:

./alsa-info.sh --no-upload

@Zeth, the issue of the erratic elapsed recording time you are seeing is likely bug 282316 and should be resolved with the latest updates to alsa-plugins. Thanks.

[EAB (adair-boder)]

I have reverted to Hardy after having far too many issues with Intrepid, including kernel panics.

I can definitely confirm that the mic issue was not solved in Intrepid with kernel 27-9 and under.

[sibidiba (sibidiba)]

I just upgraded to Intrepid. No change on the issue:

- internal mic still not working

- external mic still recognized as internal one

- input from external mic still remains unrecognizable

[skflyfish (jpeasley)]

http://www.vnunet.com/vnunet/news/2231970/ibm-readies-ms-free-desktop

As IBM has partnered with Canonical to help provide a MS free desktop, I hope this bug gets a bit higher priority. I work for an IBM business partner, and as much as I love Ubuntu, the internal mic and sound resume after suspend problems would make it hard to recommend Ubuntu to clients.

I personally won't be going back to MS as I love Ubuntu that much, but the sound issues in Ubuntu with regards to IBM/Lenovo machines, needs to be resolved before it can be main stream.

[Rami Al-Rfou' (rmyeid)]

@skflyfish

We all hope to make Ubuntu the best. This is a technical bug tracker, we are asked to report debug traces, configuration files and description to problems. I think ubuntu forum is better to discuss such news for IBM and canonical ;).

Anyway, I am asking if there is a mentor available, so I can spend my free time to dig the problem to solve in the upstream kernel.

[sibidiba (sibidiba)]

I'm not a kernel hacker, but I'm currently seriously hurt and disappointed by this bug.

I've huge experience in programming, and own an affected machine, I would gladly help in testing.

[EAB (adair-boder)]

I would be happy to help in any way I can as well.

Does anyone know if this bug is being worked on at all?

[TimoVersemann (tversemann)]

same problem on my thinkpad r61 with xubuntu8.10. no internal- and no external-mic.
Codec: Analog Devices AD1984

[skflyfish (jpeasley)]

Does anyone know if this issue will be addressed in 9.04?

Thanks,

[Rami Al-Rfou' (rmyeid)]

I tested alsa 0.1.19 in my intrepid with no success. Actually now sound input is worse

[Rami Al-Rfou' (rmyeid)]

I upgraded to Jaunty with using alsa 1.0.18 and kernel 28-8 I can not find any improvement. Actually the output become also worse.

I tried to discuss this issue with audio team, and I think they are aware enough of the mic regressions that ubuntu users have. you can see that in the http://irclogs.ubuntu.com/2009/02/26/%23ubuntu+1.txt @[22:27]. Let us hope it will work.

[c4pp4 (c4pp4)]

Could someone please test my patch? I fixed built-in mic, PCM db gain and added Mixer capturing.
http://www.alsa-project.org/db/?f=2764204e4a4a2a3b5ce726467d741ca98ac0d228

[c4pp4 (c4pp4)]

There is a new model named "lenovor61i" inside attached patch_conexant.c file, so if your Subsystem is not 17aa:20ac but Node 0x14 is Ext Mic and Node 0x15 is Int Mic, you can try to use it, otherwise it's not necessary. I cleared Ext Mic and Int Mic sliders because they were useless.

[c4pp4 (c4pp4)]

First of all, patch is not included in the alsa git yet. I think it's important to discuss it before.

Example for applying the patch (I tried it with Intrepid and Jaunty; please don't do that if you don't know what's all about):

Download attached AlsaUpgrade-1.0.x-rev-1.16.sh script modified for conexant codec (upgrade to alsa 1.0.19; originally it's from here http://ubuntuforums.org/showthread.php?t=1046137).
Download above attached patch_conexant.c.patch file.
Launch AlsaUpgrade script with option -d (download the packages only):
sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -d
Check /var/log/AlsaUpgradeRev-1.16-XXXXXX-XX.XX.log file if there was no problem.
Apply the patch:
sudo patch /usr/src/Alsa-1.0.19/alsa-driver-1.0.19/alsa-kernel/pci/hda/patch_conexant.c patch_conexant.c.patch
If there is no problem launch AlsaUpgrade script with option -i (compilation and installation of packages):
sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -i
After that, check /var/log/AlsaUpgradeRev-1.16-XXXXXX-XX.XX.log file if there was no problem.
Find out your subsystem id:
lspci -vnn | grep -A1 Audio
If you don't have subsystem id 17aa:20ac and you think that it could work, include "options snd-hda-intel model=lenovor61i" at /etc/modprobe.d/alsa-base file.
Then reboot.

Launch alsamixer:

F3 - playback controls: Master; PCM; IEC958; IEC958 Default PCM
PCM slider ought to be now at 100 with db gain 0.00, so there is no more distorted sound over 0.00 db.

F4 - capture controls: Mixer; (Digital?); ExtMic; Input; IntMic
Select capture source among Mixer; ExtMic; IntMic by pressing SPACE on it.
Input slider: lowest level is best for Mixer, highest level is best for Mics; if you press SPACE on it, you turn off capturing at all.
Digital slider: I don't know why it appears, leave it at 50 (db gain 0.00).

I have two questions:
How to name Mixer and Input slider? (or let it be as it is)
Do you want Ext Mic and Int Mic sliders back? (i think it's useless, it does nothing)

Thank you for testing.

[c4pp4 (c4pp4)]

If you use Gnome Sound Recorder (happens in Intrepid) watch out for alsamixer capture sliders setting, after the launch, it turns off capture flag for Input slider and sets lowest level for Digital slider, so you have to set it back.

[Jaap Hoetmer (jaap.hoetmer)]

Works great for me, PCM no longer distorts sound and can be set to max, and microphone works at last! I am a happy man, thank you!

[jhoechtl (johann-hoechtl)]

Will this also fix the Connexant Issue with Hermosa codecs?

cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Conexant CX20561 (Hermosa)

lspci -vnn | grep -A1 Audio
00:07.0 Audio device [0403]: nVidia Corporation MCP65 High Definition Audio [10de:044a] (rev a1)
        Subsystem: Hewlett-Packard Company Device [103c:30cf]

No way for me to test the patch ....

[c4pp4 (c4pp4)]

No, because it's a different codec. CX20549 (Venice) = Conexant 5045 and CX20561 (Hermosa) = Conexant 5051.
Have you tried model options "laptop" or "hp" at "/etc/modprobe.d/alsa-base"?

[KathaL (k-luedke)]

After applying the patch rhythumbox, video-player and audiorecorder (gstreamer??) didn't work any longer... But youtube and vlc work and skype does recognize the micro at last.

Any ideas?

[skflyfish (jpeasley)]

I finally get a mic that works in Skype now. The digital input comes set
to 50% and works well at that setting. This makes me very happy!

The PCM playback does not distort anymore but some Hulu videos have the
sound levels recorded kinda low and they are hard to hear now. Amarok
works well with the changes as do the video plugins in Firefox.

Thanks!

[c4pp4 (c4pp4)]

KathaL:

I think it's a pulseaudio vs. alsa problem and has nothing to do with the patch, for example try to force either pulse or alsa in Gnome Sound settings.

[jhoechtl (johann-hoechtl)]

@c4pp4 I added this line, but I do not have a problem with audio output but I experience the same problem as described in this thread. So I hoped that a fix for Venice codec would also fix mine with Hermosa codec.

Should I open a separate bug report? My strong suspicion is that Venice fix will fix Hermosa too, as exactly the problems described apply.

[c4pp4 (c4pp4)]

@jhoechtl

Unfortunately, as I said, it's not the same codec. Look at Venice: http://helllabs.org/codecgraph/out/hp-spartan.svg and Hermosa: http://helllabs.org/codecgraph/out/hp-spartan-ng.svg

There is no need to open a new bug because it's already opened here: https://bugtrack.alsa-project.org/alsa-bug/login.php?username=guest&password=guest&return=/alsa-bug/view.php%3Fid%3D3964
You should send to bugtrack of alsa the output of alsa script: http://www.alsa-project.org/alsa-info.sh and the output of codecgraph tool: http://helllabs.org/codecgraph/
If I'll have some time, I'll check it and try to find a solution.

[jhoechtl (johann-hoechtl)]

@c4pp4: Ok, added a note to the report on
https://bugtrack.alsa-project.org/alsa-bug/login.php?username=guest&password=guest&return=/alsa-bug/view.php%3Fid%3D3964

alsa-info is at

Output of codecgraph upon request, but i guess it should be the same as
http://helllabs.org/codecgraph/out/hp-spartan-ng.svg

[EAB (adair-boder)]

Is this issue anywhere near being resolved? Is there any other distro that would work fine in regards to audio input?

[c4pp4 (c4pp4)]

I removed old patch because I rewrote it. I removed mixer, renamed model to "lenovo" and now it automatically changes between built-in mic and mic jack, so there is no need to change it manually (there is no options), overriding max PCM level to 0 dB stays.

I don't know, how to apply patch to alsa project, could anyone help please?

There are two attached patches (first file is mic and pcm patch, second one is model name patch, both against alsa-driver-1.0.19) here: https://bugtrack.alsa-project.org/alsa-bug/login.php?username=guest&password=guest&return=/alsa-bug/view.php%3Fid%3D4163

[EAB (adair-boder)]

Today 'another' update to proposed kernal 2.6.27-14-generic was downloaded and applied and now all sound (in and out) does not work on my R61. If I go back to kernal 2.6.27-13 I get sound out again. I am unsure if I need to re-apply the patch, or what.

[c4pp4 (c4pp4)]

@skflyfish

Sound works on my install of Ubuntu 8.10 after the update.

@Zeth

try the command:
aptitude show linux-image-2.6.31-16-generic | grep -e "State" -e "Version"

it had to show:

@c4pp4

output is:

State: installed

This morning I booted up and noticed that the mic was picking up sound (which was not the case yesterday) but that Skype was not picking up the input. I disabled allowing Skype to manage the mixer levels and readjusted the mic volume to 100% - and Bingo - back to normal! :)

[EAB (adair-boder)]

I just updated to the 2.6.31-19.56 kernel and noticed that it's not the one from the PPA ... so mic not working and sound all distorted again ...
I checked for more updates and nothing was found even though I have the repo in my sources and it was working smoothly in my previous kernel and all kernel's before that.
I went here (https://launchpad.net/ubuntu/karmic/+source/linux/2.6.31-19.56) and noticed that the only package listed was labeled "2.6.31-17.54ubuntu1~ppa1~karmic1" so it's not the one that I need.
Where do i get the package update that I need for my 19-56 kernel?

[skflyfish (jpeasley)]

Zeth,

c4pp4 has been graciously been providing the corrected kernel when each
one comes out. (many thanks c4pp4) I just got 2.6.31-18 today from the
pre-release repository. I kinda doubt if c4pp4 has had a chance to apply
it to 2.6.31-19.

Here is his PPA. http://ppa.launchpad.net/c4pp4/cx20549/ubuntu

Hi Zeth,

Sorry it was late for me when I last replied. I just received 31-19 from
the pre-release updates/repository. I get pre-release updates by; Admin
----> Software Sources ----> Updates tab ------> tick the Pre-Release
updates. I am using Karmic 32 bit, btw.

c4pp4 usually comes out with his path after the new kernel comes is
released. So his patch for 31-18 and 31.19 may be forthcoming. Hopefully
all is well with c4pp4. Again I appreciate your work!

You received this bug notification because you are a direct subscriber

of the bug.

[EAB (adair-boder)]

I continue to get the update for the wrong kernel before the PPA version comes out ... is there a way to make this not happen? My sound gets completely messed up and distorted each time my kernel updates ...

[EAB (adair-boder)]

What does it take nowadays for a bug fix to be implemented in the official kernel?

[EAB (adair-boder)]

I really need the patched kernel .... c4pp4 .... you around still? :)

[c4pp4 (c4pp4)]

Summary:

command:
lspci -vnn | grep -A1 Audio
output:
00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 03)
Subsystem: Lenovo Device [17aa:20ac]

command:
cat /proc/asound/card*/codec\#*|grep -i codec
output:
Codec: Conexant CX20549 (Venice)

Problem with it:
Lenovo R61i built-in microphone doesn't work at all.
Lenovo R61i and Fujitsu V5505 [1734:110e] output sound is distorted when volume is 100% because PCM level is over 0db (e.g. bug #285866,#290463,#291798,#461521).

Solution:
To correct situation you can update your system with package from my PPA by adding ppa:c4pp4/cx20549 to your system's Software Sources.
(https://launchpad.net/~c4pp4/+archive/cx20549)
New update comes out about a week after the official kernel so please be patient and upgrade later from my PPA (except critical security reasons!).

You can force setting (in case of different subsystem id) by editing /etc/modprobe.d/alsa-base
- with "options snd-hda-intel model=lenovo" for Lenovo R61i settings (mic and pcm)
- with "options snd-hda-intel model=laptop-hpmicsensepcm" for Fujitsu V5505 settings (pcm)

I'm also including patch for Karmic and Lucid.

[c4pp4 (c4pp4)]

Karmic patch.

[c4pp4 (c4pp4)]

Lucid patch.

[EAB (adair-boder)]

Cool .. Sorry, I did not mean to seem impatient. Thanks for clarifying the "release schedule" for the patched kernel.

Can I what the other patches are for? Are they so we can apply the patch ourselves to our running kernel?

Also, would the setting for the R61i be the same for the R61?

Thanks again for all your support!

[c4pp4 (c4pp4)]

@Zeth
Answer1: You can't apply it to running kernel, you must recompile kernel to apply it.
Answer2: I think so, it's the same subsystem 17aa:20ac, isn't it?

[EAB (adair-boder)]

@c4pp4
Yes, it would seem we have the exact same hardware, at least with audio.

zeth@zeth-r61-64:~$ lspci -vnn | grep -A1 Audio

First off this is NOT a complaint. ;-)

Can anyone point me to the procedure for having a fix permanently applied to the kernal? I am not familiar with the process and would like to know.

Thx,

[Angus (eightmillion)]

I have the same hardware:

$ lspci -vnn | grep -A1 Audio
00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 03)
        Subsystem: Hewlett-Packard Company Device [103c:30d9]
$ cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Conexant CX20549 (Venice)

I added c4pp4's PPA and now I have no volume controls for the internal or external mic. Before, I had volume sliders. Sound works fine both before and after upgrading the kernel. The microphone just doesn't work either way.

[c4pp4 (c4pp4)]

@Angus

1)
Right click and "Save as" the link: http://www.alsa-project.org/alsa-info.sh

Terminal:
chmod +x utils_alsa-info.sh
./utils_alsa-info.sh

Yes to "Automatically upload ALSA information to www.alsa-project.org?"

Give me the link.

2)
Have you changed /etc/modprobe.d/alsa-base with "options snd-hda-intel model=lenovo"?

[Angus (eightmillion)]

c4pp4,

1)
That alsa-info.sh script does not give me a URL when I tell it to upload the information. It just outputs "Your ALSA information is located at", with no URL. I took the output file from /tmp and uploaded it to pastebin here: http://pastebin.org/170674

I hope that's what you need.

2)
Yes I have added that line to /etc/modprobe.d/alsa-base. Without that line, there's no difference from before switching kernels.

Thanks for your attention.

[J.P. (mackdieselx27)]

For what it's worth I'm currently testing the Lucid RC and the problems with the mic and elevated sound levels still persist. I have a bug open at 476174 for those interested in the apport-collect output. Unfortunately I can't test the mainline kernel (using the live CD right now) so if someone wants to help out, have at it.

[c4pp4 (c4pp4)]

@Angus
Your hardware is not the same. Go back to the official kernel release, edit /etc/modprobe.d/alsa-base and try models: "laptop-hpsense", "laptop-micsense", "laptop-hpmicsense", "benq", "laptop-hp530" and "test". Email me a result.

[jaygade (jaygade-yahoo)]

@c4pp4
Been trying to track down a fix for this and no dice so far.
I added "options snd-hda-intel model=lenovo" to my alsa-base.conf. I had also tried "model=thinkpad".

Then I tried the Alsa-Upgrade and brought my version up to 1.0.23.

Then I applied your Lucid-patched kernel from your PPA with the same result: playback works, but still nothing on the mic. I've tried adjusting levels with alsamixer with no result.

My alsa-info.sh output is here: http://www.alsa-project.org/db/?f=b4cf4902ab704c1fc4aa2ada9c11d72a086b2f4e

Hardware is a Lenovo Thinkpad R61i 8932-A54, running Ubuntu 10.04. I think the other info is in the alsa-info output.

Thanks for your help on this.

[c4pp4 (c4pp4)]

First of all - I removed Modified Alsa Upgrade script because it's obsolete.

@jaygade

you wrote: Then I applied your Lucid-patched kernel from your PPA with the same result: playback works, but still nothing on the mic. I've tried adjusting levels with alsamixer with no result.

Patched kernel from my PPA has no mic levels in alsamixer!

I recommend a clean install of Ubuntu. Then add my PPA and upgrade kernel from it. Sound and mic should be ok because your hardware codec is the same as mine. Don't specify model to alsa-base.conf because your subsystem id is correct (17aa:20ac). Use sound applet to adjust mic volume level.

[EAB (adair-boder)]

I can confirm that the Lucid patched kernel works in Ubuntu 10.04 after upgrading from 9.10.
Thanks c4pp4!

[jaygade (jaygade-yahoo)]

Okay, I was hoping not to have to reinstall but that did the trick. Thanks!

I had previously been running wubi Ubuntu 9.04 and then 9.10 on this laptop but was dismayed at the lack of microphone (and the overdriving of the speakers, though that wasn't as bad). Now I'm running a full install and with your fix the microphone and speakers seem to be working just fine.

Thank you very much!

Any chance this will be patched in permanently or does it break others' setups?

[c4pp4 (c4pp4)]

I've rewritten the patch. No changes, I've just reduced the code. I'm removing old patches and including new one for Lucid.

@jaygade
I think it's up to Daniel T Chan. It doesn't break anything.

[skflyfish (jpeasley)]

I am wondering if @c4pp4's work was integrated into kernel 2.6.32-23?

After upgrading to this kernel, the output volume matches his patch.

Unfortunately, the mic still doesn't work.

Thx,

[c4pp4 (c4pp4)]

@skflyfish
Upgrade Lucid from my ppa (it doesn't upgrade lucid-proposed!):

sudo add-apt-repository ppa:c4pp4/cx20549
sudo apt-get update
sudo apt-get upgrade

[c4pp4 (c4pp4)]

The last Lucid kernel release (2.6.32-23.37) fixes Lenovo max PCM level to 0 dB. I am very happy that the Lenovo sound is no more distorted.

BUT:
The fix was added by Daniel T Chen on Mon, 10 May 2010 19:50:04 +0000 (21:50 +0200):
http://git.alsa-project.org/?p=alsa-kernel.git;a=commitdiff;h=0ebf9e3692d640917fb792a7494d05e1f5b1058f
based on Tim Starling request on Mon May 10 09:15:51 CEST 2010:
http://mailman.alsa-project.org/pipermail/alsa-devel/2010-May/027525.html
It taked only one day from the request time to the apply time.
The fix here is more than a year (successfully tested) and nobody (from developers) was interested :-(

Anyway I've removed that part (fixing max PCM) from the patch.

[Donny Kurnia (donnykurnia)]

@c4pp4, many thanks for your effort to provide this patch. Too bad the kernel developers still not willing to integrate it into the main kernel.

[skflyfish (jpeasley)]

@c4pp4:

I have a Fujitsu-Siemens V5545 using a Conexant CX20549 (Venice) chipset. I applied your patch but the microphone is still not functional. When using the "lenovo" model the input devices disappear from my list of devices as shown by "alsamixer -D hw:0".

When using the "laptop-hpsense", "laptop-micsense", "laptop-hpmicsense", "benq", "laptop-hp530" models, and AFTER I unmute and raise the volume level for my input devices inside "alsamixer -D hw:0", I can hear some crackling noise coming from my laptop's speakers when I plug / unplug my external microphone. Even so, the microphone does not appear to actually work - trying to record something in Audacity results in silence (actually in a slight "digital equipment"-like noise).

When using the "test" model and after raising the volume level for all devices I can find in "alsamixer -D hw:0" I can't even hear that crackling noise...

What do you suggest I should try next? I'm not work-shy and don't expect solutions to be delivered on a plate, so please do tell whatever you have in mind.

A variation of the patch attached here seems to be applied to Natty. Could someone with this hardware please test a natty kernel and confirm whether it works there. Please report any testing here. Thanks.

[c4pp4 (c4pp4)]

@Andy Whitcroft
I'll prepare a Natty ppa kernel to test.

[c4pp4 (c4pp4)]

Natty ppa kernel ready to test: https://launchpad.net/~c4pp4/+archive/ppa
I have patched version "2.6.38-7.36".
The patch is attached.

@Andy Whitcroft
Tested on my computer and everything is OK

[c4pp4 (c4pp4)]

@Andy Whitcroft
I forgot to note that without the patch it doesn't work.

What's the situation with 11.04?
I added the repo info and imported the key ... did apt-get update and apt-get upgrade, but nothing took ..

[c4pp4 (c4pp4)]

@Zeth

The situation is very simple. I made the natty patch and the natty ppa for testing (see #140). Nobody was interested, nobody told me why the status is still incomplete, so I deleted the natty ppa after some time.

Now I'm providing what I'm using = the repo is only for Ubuntu 10.04 LTS.

10.10, 11.04 and 11.10 doesn't work out of the box. Still the same bug.

@c4pp4

I am very sorry to hear that after all your hard work your fixes are not being properly noted! It's a real shame!

Would you still be able to upload the fixes for 11.04, or is that no longer in the cards!?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[c4pp4 (c4pp4)]

@Zeth

Sorry, as mentioned previously - now only ppa for 10.04.

[EAB (adair-boder)]

"Status changed to 'Confirmed' because the bug affects multiple users."

Is this a good thing? :)

[EAB (adair-boder)]

Oh cool!!! Thanks so much c4pp4 ... how do I go about applying this patch to my system?

[c4pp4 (c4pp4)]

BTW ... c4pp4 ... thanks for the patch! It works a treat!

One thing I am wondering though .... when i boot up the mic is muted and the speaker volume is way down ... is this normal?

[c4pp4 (c4pp4)]

@Zeth

I think that you have attached useless data because it's after the applying the fix. I'll do it.

Muted mic and zero volume isn't normal, I think it has nothing to do with the patch but with your upgrade from previous version. Try to remove from home folder the hidden folder ".pulse". I just guess - I really don't know.
