cannot hear sound in LG P1 Express laptop

[Mhatz]

 I have an LG P1 Express laptop and I always had this kind of problem. It seems tha ALC883 codec from Realtek can be recognised but I have no sound through speakers. When I connect headphones I can hear sound but low.

I am using ubuntu 9.10 RC, but i had this problem with 8.04, 8.10, 9.04.

Please try installing linux-backports-modules-alsa-karmic-generic, and rebooting. Let us know if that solves your problem.

Thanks.

[Mhatz (hatzimiltos)]

I did so but still I have no sound from the speakers. But through headphones, I can hear it loud and clear! In previous versions of Ubuntu, the sound was not so clear. Anything else I may post that can be helpful?

[Mhatz (hatzimiltos)]

I guess there is no solution to it?

[philhachey (philhachey)]

I have had the same problem for over a year now.
If anyone could figure it out that would be amazing.
It would also be the last hurdle that keeps me from running Linux as my #1 OS.

@Phil
Please use apport-collect -p alsa-base 460330

[Mhatz (hatzimiltos)]

Guys, after upgrading to kernel 2.6.31-15-generic no soundcard can be identified through the sound preferences!

[philhachey (philhachey)]

Today I started my system and heard the startup sound! And then nothing.
Linux is a cruel mistress.

[Mhatz (hatzimiltos)]

I did a new fresh installation, with Karmic final release today, and I ve noticed a few things: When I install it with the kernel 2.6.31-14 the soundcard is detected but there is no sound from speakers. After the upgrade to 2.6.31-15 kernel there is no soundcard detected! The odd thing is that when I boot to 2.6.31-14 the soundcard is not detected either (it was detected before)!!!!! Could it be something else? Could it be an update to alsa probably? Any help would be appreciated, I use Linux as my primary OS, I don't want to migrate back to Vista again.

[Mhatz (hatzimiltos)]

Ok, fixed the problem with the disappearing of the soundcard. It has to do with an analog modem that resides in the soundcard. When I installed the driver, then the card disappeared. Uninstalling it fixes the problem.

But still no sound from speakers.

Is there something that we can do? I mean how may I test to see where the problem is?

[Daniel T Chen (crimsun)]

Look at your amixer (in a Terminal) output.

[philhachey (philhachey)]

 @mahatz
I did some googleing last night and came across this link:

http://linuxinside.blogspot.com/search/label/alsa

Looks like this guy has it figured out in Karma. I tried some of his tips last night but had no luck in
Mint 7 Gloria.

Let me know how it goes.

[Mhatz (hatzimiltos)]

@philhachey

Thanx for the info. I have tried all of the above but still no luck. After the new kernel 2.6.31-16, still no sound.

Hi,

This was/still is my problem every time a new release came. I had no better luck with other distros like openSuse, but that was sometime ago. I also have a P1 express dual and the following thing should work for you too.

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

Go to the end of the file and add this line:

options snd-hda-intel model=lg

Save the file.
Now with Karmic I had to install linux-backports-modules-alsa-karmic-generic:

sudo apt-get install linux-backports-modules-alsa-karmic-generic

Reboot.
Have Fun!

Kind regards,
mdaniel

[philhachey (philhachey)]

Hi, Mdaniel

    I have just done a fresh Karmic install and followed your instructions with no luck.

Could you please let us know if you are using the Raltek ALC883 codec.

[mdaniel (daniel-majsai)]

Hi,

One step is missing from my post. Sorry for that.
I also had to remove a package:

sudo apt-get remove sl-modem-daemon

Post reply if it did the trick!

Cheers,
mdaniel

[philhachey (philhachey)]

Still no luck.

Could you please post the output of :

~$ aplay -l

Happy New Year!

Mhatz,

Add the line:
options snd-hda-intel model=laptop-eapd
To the end of /etc/modprobe.d/alsa-base.conf

And it should work!

Best wishes in 2010

[philhachey (philhachey)]

Mhatz,

Did this work for you?

[Mhatz (hatzimiltos)]

Phil,

 Sorry I haven't responded for so long. You are the MAN! It's been three years without sound but YOU GOT IT MAN! Thanks SO MUCH!

My best wishes too!

-Mhatz

[Mhatz (hatzimiltos)]

Phil,

 I come up another problem now. Even with headphones on, the speakers still play! Do you have the some thing too?

-Mhatz

[philhachey (philhachey)]

Yea same problem here but I never noticed because I never use headphones.

As for the laptop=eapd:

It's the setting for a Clevo M540JE, M550JE that seems to work OK for our model.

I guess that ALSA never made support for certain models with the 883 codec.

Examples can be found in this post:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/106634

Here is where it gets depressing.

This problem has been reported on the ALSA bugtracker:

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3544

Notice that the last post is dated 2008-11-09.

Looks like if we want decent working sound we better learn to program.

[Mhatz (hatzimiltos)]

Nice research Phil! I wish I had some time to check it out myself but I am too busy to do so. It's sad though, that even though it has been reported as a bug, nobody showed any interest. Anyway, maybe I ll find some time and read the code myself and find out a solution.

[Brad Figg (brad-figg)]

Hi Mhatz,

Please, if you are still having issues, test 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 alsa-base 460330

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.

[Chris Rosenhain (hydra-internode)]

Hi,

I've experienced the same bug on the same laptop.

My solution was to modify /etc/modprobe.d/alsa-base.conf and add the following line:

options snd-hda-intel model=laptop-eapd enable=1 index=0

Reboot, and with any luck you'll be welcomed with the Ubuntu sounds! I have tried this on 8.10 -> 10.04 Beta 2 and it worked every time.

[Chris Rosenhain (hydra-internode)]

Oh - I also have reported this bug previously here:

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/296251

[philhachey (philhachey)]

Hey guys,

Just a quick heads up.

I upgraded to ubuntu 10.04 last week and used the same laptop-eapd workaround for sound. Everything was going fine. Until I opened up the sound preferences and noticed there was still some room on the volume slider to increase the volume. So I cranked it up. A few min went by before I heard an electronic feedback sound and then nothing. Nothing in windows either. Although I still get sound from the headphone jack.

I think what happened is the sound card got fried from using the wrong settings. So be careful.
