No internal mic on LG R510 laptop (Intel HDA ICH9, ALC268)

[claudio]

I have already asked this as a question but I am now reporting it to be a bug, as I've tried several things to fix this myself.

I have tried upgrading to the last alsa version and also changing the model in the alsa-base.conf file. Since Karmic it is now not necessary to use de model option to hear sounds. Before Karmic, I was using model=toshiba.

Several models work for this particular sound card, but none of them recognises the microphone. When I say microphone I am talking about internal microhpone, plugging an external one works properly.

When I record sounds with Audacity (or any other software) I only hear noise (like "fffffff"), but I never hear my voice.

I provide here the alsa-info.sh output: http://www.alsa-project.org/db/?f=32ec89682bee5649c684198911df985a0fd281e9

Hi claudio,

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 495134

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.

Doesn't matter, when I raise it to 100% all I get is noise.

Can you reproduce this symptom using linux-alsa-driver-modules-$(uname -r)
from ppa:ubuntu-audio-dev? If so, does adding the following line to
/etc/modprobe.d/alsa-base.conf (and rebooting) resolve the symptom?

options snd-hda-intel position_fix=1

I can't reopen the bug, i get an error. I get the same error if I try to
post in the web, I only can from my mail. I thought it was because of
the referer, but after check it I saw I have it in "send always mode".

[carlosjcabello (carlosjcabello)]

Reopened.

This bug needs to be solved.

[David Henningsson (diwic)]

I've been trying it with the latest upstream code, where it seems like it should work. No auto-switch though.
That is, try installing https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules , then reboot. You'll have to select what mic you have manually, e g in gnome-volume-control (try both "Microphone 1" and "Microphone 2") or alsamixer (Input source should be set to "Front mic" - the external mic is labeled just "Mic").

Report back whether it worked or not. Thanks!

[carlosjcabello (carlosjcabello)]

It didn't work ...

[David Henningsson (diwic)]

@kbyo, thanks for testing, I'm a little surprised that it didn't work though. Can you attach an alsa-info according to https://wiki.ubuntu.com/Audio/AlsaInfo (with the latest drivers installed, according to comment #42), to see if that gives me a hint?

[carlosjcabello (carlosjcabello)]

David, thank you for the help

Here is the Alsa information:

https://docs.google.com/Doc?docid=0ARYsuNZK7EX4ZGhnZDY3d2JfMTA1ZDh3ZGg3Y3A&hl=en_GB&authkey=CPGmr8kJ

[David Henningsson (diwic)]

@kbyo, can you try model=auto, that is, in /etc/modprobe.d/alsa-base.conf, add this line:

options snd-hda-intel model=auto

Reboot, and see if it works? If it does, please also test whether everything else (speakers, headphones, external mic) works as expected. Thanks!

[carlosjcabello (carlosjcabello)]

@David, it worked! But the sound level is quite low. When I change the level to 100% from No amplification the quality of the sound is very bad, but at least I can hear my voice!
Speakers, headphones and so on work correctly.

[David Henningsson (diwic)]

@kbyo: Do you know if the quality is what you would expect from an internal mic (many of those are not very good), or do you think something is still broken?

[carlosjcabello (carlosjcabello)]

@David, the quality is not the better (there is a slight background sound/noise) but I think is enough. I have found a compromising solution between the quality and the sound level.
In Windows the quality is much better but the quality in Ubuntu is enough as I have said.

[claudio (claudio-noguera)]

It works!

Skype working properly.

[David Henningsson (diwic)]

Thanks for reporting back, patch sent upstream: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-August/030372.html

[Alejandro P. (pintadus)]

Thanks a lot!!!!
Great!!
Finally Skype working!!!

[Martin Pitt (pitti)]

Accepted linux into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Steve Conklin (sconklin)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by Thursday, November 11, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Steve Conklin (sconklin)]

Due to national holidays, the deadline for verification of fixes for the -proposed kernel has been extended thru Monday, November 15th.

If verification that this bug is fixed by the -proposed kernel has not occurred by that date, the change will be reverted and this bug will be set to incomplete.

If you have tested the kernel in -proposed and found that it fixes the bug on the original hardware, please change the bug tag "verification-needed" to "verification-done".

The new stable kernel release process under which these actions are being taken is still being refined, and is documented here:

https://wiki.ubuntu.com/Kernel/StableReleaseCadence

Discussions about the new process tend to take place in #ubuntu-kernel on IRC, so please contribute to the discussion there if you would like.

Thank you!

[buzonn (buzonn)]

Oh, sorry, I didn't read that. I'm using now 9.10. I tried only the maverick livecd and I think It worked.

[Brad Figg (brad-figg)]

This patch was applied as a "pre-stable" patch. It has not come in via a stable upstream patchset so does not need to be re-verified.
