No sound on Acer Aspire 8920G with H.Heron 8.04 Beta x86_64 and Realtek ALC889 and Intel HDA 82801H

[Patrick]

Hi,

I have a sound problem with my ACER ASPIRE 8920G.
I did everything : installation linux-backport-modules, changes in alsa files....reboot, compilation of new alsa driver but despite that....same problem : no sound at all : on headphones nor on speakers.....nothing at all ! ;-(
I am on Hardy 8.04 beta with x86_64.
In addition : I also tried the way to download the last driver, e.g. alsa-driver-1.0.16rc2.tar.bz2 here : ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.16rc2.tar.bz2 (last release i found) Then i extracted it, compiled it and installed it.... No improvements (i checked again everything with alsamixer, sound properties, and so on...). No errors also during the reboot. The sound still is definitively silent..... ;-(((

Here are some data who can be useful for you to solve this bug (concerning essentially Acer laptop it sounds, according to what i saw before...) :

It seems to me I have the same problem but on a Dell (inspiron 1420). I pasted below the output of the same commands that the one Patrick gave (and I don't understand everything).
Thanks for the help.

[Lionel VICTOR (lionel-victor)]

Hi,

Same problem here... (info below)... Updated from feisty to hardy RC... Now snd-hda modules aren't working and I have no sound card detected at all.

Of course they used to work like a charm, otherwise I wouldn't be posting here !

My host is a dell laptop XPS M1710

- rt kernel do give sound... OK
- my old kernel (from feisty) has sound as well... OK
[however, a lot of things like my GPU are not usable anymore with those two kernels... and I guess you definitely want to fix this bug because hda drivers are somewhat popular and you can't afford to break them can you ?!]

In my case

sudo alsa reload

This is doing nothing to me except "unload failed snd-hda-intel....."
The sound is still not present :-(

Hope the ubuntu team can do something for all of us....

Patrick.

[Patrick (ccz)]

Now I am on the official Ubuntu 8.04 x86-64 (generic)
And I still have the same troubles....
It sounds that the new LTS release has not solved the sound problem.
All the output I have are exactky the same than before, except :

What is strange again, is to see that Mixers are on this time (but no sound out...), and this ALC883 Analog is coming back. My chipset is on ALC889 NOT ALC883 !!!!!!!!!!

PS: I have the last release of alsa base , i.e. 16

I am very disappointed the new release has not solve this sound problem.

WHat should I do : come back to Micro$hit ?????

please HELP(SAVE) US !!!!!!!!!!!

I'm not sure if the absence of sound stems from the same bug (given that we don't have the same audio device).

Furthermore, I was wrong in my earlier post. I need to type:

(and not sudo alsa reload) at the beginning of the session to have the sound.

François

[warmcat (andy-warmcat)]

I have an Acer Aspire 8920g and Alsa's snd-hda-intel does not have a model that works completely on it yet. However after some help on the Alsa lists, I was able to get it working for stereo anyway on internal speakers. See this post:

http://mailman.alsa-project.org/pipermail/alsa-devel/2008-May/007653.html

This is on Fedora 9, but it is not a distro-specific issue (assuming your distro builds the kernel with CONFIG_SND_HDA_HWDEP anyway, otherwise you are into rebuilding alsa with that option as well as the applet mentioned in the post above).

[lud3e (ludde33)]

Do any of you guys have the network card up and running, atheros ar8121 or does anyone now if this is just a branded version of attansic L1 Gigabit, that atheros bought lately?

´be thankful for response

regards

[lud3e (ludde33)]

Anyone with an acer 8920G or 6920G that is.

[Mike (triple-eh)]

I have an Acer Aspire 6920G and I am experiencing the same issue with Ubuntu Hardy Heron amd64.

I tried the suggestion posted earlier, http://mailman.alsa-project.org/pipermail/alsa-devel/2008-May/007653.html.

This did not yield positive results: the audio is still silent.

These are the steps I took:
1) sudo vi /etc/modprobe.d/alsa-base
2) added new line "options snd-hda-intel model=acer-aspire"
3) sudo ./hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2
4) restart

Any further help and ideas are greatly appreciated!

[Carl-Erik Kopseng (kopseng)]

Seems Acer has a real problem with Ubuntu. On the alpha versions of Hardy I also didn't get sound, but this got better with the release of the beta. BUT after resuming from standby/hibernation the sound is gone :(
Maybe putting sudo alsa force-reload in the init scripts will fix thing - will check it out.

[Carl-Erik Kopseng (kopseng)]

Just needed to add that the sound always worked in 7.04, but then the hibernation/standby functions didn't function, so the problems might have been there already then.

[Peter Delahunty (peter-delahunty)]

Hi all

To get the ethernet card working on an Acer 8920g follow my instructions at the bottom of this link http://ubuntuforums.org/showthread.php?t=770173

Still trying to sort out the sound.

regards Peter

[Mike (triple-eh)]

I've found a temporary solution for sound playback using OSS4 rather than ALSA.

The instructions are found <a href="http://ubuntuforums.org/showthread.php?t=780961&highlight=oss4">here</a> at ubuntuforums.org.

[jagnet (jagnetx)]

Thanks for that Mike.
I can confirm this works on my Acer 8920G in 8.04 32bit AND 64bit

Though the sound it a bit basic and quieter than it could be with full drivers. (OSS only enables the 2 smallest speakers on the front of the laptop)
Is anyone working on a proper fix to get all 5.1 speakers working in either ALSA or OSS? .....I hate having to load Vista anytime I want to watch a good movie :(

[M-A Loyer (weirdfox)]

I have the same problem with a ACER Aspire 6920.

I can't get alsa to work even by compiling the latest sources (Ubuntu 8.04 64bit) and I tried almost all "model" kernel options, with no luck...

The only way to get sound out of the speaker is using OSS4, but headphone detection does not work (must mute manually speakers), the sound is not very loud and only 2 channels are detected... and it does not automatically save mixer setting on reboot...

Anyone found more tweeks or workaround for these Alsa/OSS problems ?

[Attila Fülöp (attila-fulop)]

There is a solution to get stereo working (at least on 6920G i can confirm this works) here:
http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=852295
Though, setting the model to acer-aspire seems unnecessary, model=acer works just as well.
You can then turn on/off the "tuba" by turning on/off the "headphone" switch, very weird yes, but thats how it behaves for me..
Muting "Front" mutes the laptop speakers (including the tuba) so you can get audio out through your attached speakers only.

What still doesn't work:
-Surround (connecting 5.1 speakers to the laptop)
-Microphone

[aralbald (aralbald)]

Tested on Intrepid Alpha 6 with a Acer 6920g and the sound is not working.

The hda-verb workaround is not working either. The device /dev/snd/hwC0D0 is not created anymore. I have tested with both options 'acer' and 'acer-aspire' in the /etc/modprobe.d/alsa-base file. This is for the onboard speakers and mic, the external ones are working fine.

This is the generated output from alsa-info.sh:
http://www.alsa-project.org/db/?f=c43d9a4f3ab5398fc2208a9391abe939a3c45b71

[jagnet (jagnetx)]

jansaell has found a way to get the Acer 8920G and im sure the 6920G working 100% with ALSA. It works for me im getting all speakers working.

Check out the solution over at the forums http://ubuntuforums.org/showthread.php?t=852295 and http://jan.saell.org/blog/archives/30

[M-A Loyer (weirdfox)]

I tried this workaround on a Acer Aspire 6920-6141 and it make the sound work on the internal speakers, but that's all...

The headphone jack is not working. I can't mute all the speakers and get sound in the headphones (I tried all possible model param to the drivers and got nothing). The tuba always stay on as long as front is on and if I turn front off the headphones are turned off too.

[Jojo (kuzniarpawel)]

Confirming on Intrepid Beta on Aspire 8920

/dev/snd/hwC0D0 is not created anymore

here is my alsa info

 http://www.alsa-project.org/db/?f=48be90efeb028f289c8e5e1f59ee59bc72dd7985

[Jojo (kuzniarpawel)]

Quick workaround:
Add those lines to /etc/modprobe.d/alsa-base

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto

Internal speakers work, headphones doesn't.

[pedja_portugalac (123pedja)]

@Jojo

It work for me. Thank you very very soooooooo much.
I can hear music, great quality sounds, on integrated 5.1 speakers and my headphones works too. I was around for few days installing new alsa from source via scripts I found on forums and because of that I had to reinstall Ubuntu on and on. But with this simple two lines added to alsa-base my nightmares are over and goodbay f..... Vista. Thanks ones again and I wish you Merry Christmas and a Happy New Year...

This is what I have done:

Install fresh Ubuntu 8.10
Update system and reboot
Install proprietary graphics driver for NVIDIA cards (177) and reboot
Open terminal and type:

sudo gedit /etc/modprobe.d/alsa-base

Add this to the end:

# added by myself
alias snd-card-0 snd-hda-intel

Hi all

Since months we are trying to resolve sound problem on Acer Aspire 8920G laptops. It's High Definition Audio, 5.1 Cinematic Surround - Tuba. Other models with the same sound card have same problem.

Till now, we found only temporary solution witch enable two front speakers but today I found good news for us. Apparantly, Alsa developers together with Realtek has found solution in those latest driver (alsa-driver-1.0.19-5.11) on 2009/3/6. I found this on the Realtek official site. The only problem now is that I don't understand, very well, Ubuntu install and configuration instuctions from Realtek team. So if someone is able to get this 5.1 Surround work, please let us know with the step by step how-to like we do it on Ubuntu Forum. Thanks in advance.

The new Alsa Realtek High Definition Audio Driver package is available here: http://www.realtek.com.tw/downloads/...?keyword=Linux

The install and configuration instructions I don't understand well are:

Manual install:
Step 1. unzip source code
tar xfvj alsa-driver-1.0.xx.tar.bz2

Step 2. Turn on sound support from kernel config
(soundcore module, default turn on)

Step 3. Complied source code

c. make
d. make install
e. alsaconf
f. ./snddevices (Only kernel 2.4 does it)

Step 4. Edit your /etc/modules.conf or conf.modules depending on the distribution
(Please refer to the attached modules.conf)

snd-xxxx is the card ID.

Ok guys, after extracting LinuxPkg_5.11 and changed to that directory I didn't fallow Ubuntu instructions and run install script like this:
[QUOTE]$ sudo ./install[/QUOTE]
After that I rebooted ones and then run fallowing instruction on screen:
[QUOTE]$ sudo alsaconf[/QUOTE]
Then:
[QUOTE]$ alsamixer[/QUOTE]
And I put all first 5 columns to maximum level.

Then I downloaded 5.1 Surround Test File from: http://www.lynnepublishing.com/surround/www_lynnemusic_com_surround_test.ac3

And all 5 speakers worked. I don't know if the TUBA technology worked as well but you can trust me it was well strong volume. Played in Totem and in svn Mplayer. I could clearly hear all 5 speaker one at the time.

Hope this can be useful for the others.

From now on, new Ubuntu and other distributions realizes will come with full support for our sound card thanks to a newer alsa sound driver (1.20) coming with Karmic Koala 9.10 next month. For those who can't wait please visit this thread on ubuntu forum.

Tested on Ubuntu Keramic with Acer Aspire 6920-6141 and the sound works (Alsa 1.20) :)
I had to unmute the in alsa mixer (this should be automatic) and tell pulse that I have a 5.1 card. Now, the speakers works and the headphone sensor works too (first time with this laptop! )

The only problem left is the mic is still not working...

Patrick, thank you for reporting this and helping make Ubuntu better. Hardy (Desktop) reached EOL on May 12, 2011.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Please feel free to report any other bugs you may find.

This bug has been fixed in alsa a long time ago.
Current version of Ubuntu works well.
