Bug Description

In the default setup the external microphone is not working. It is possible to get the microphone working by editing /etc/modprobe.d/alsa-base.conf

and add this line:

options snd-hda-intel model=medion

but then there is no jack sense anymore and sound will go through the speakers, making it impossible to use this laptop for skype in a public place.

I tried a lot of different options in alsa-base.conf, but it was either no jack sense or no microphone:

jack sense but no mic -> options snd-hda-intel model=laptop
no jack sense but mic -> options snd-hda-intel model=auto
no jack sense but mic -> options snd-hda-intel model=3stack-dig
no jack sense but mic -> options snd-hda-intel model=3stack-6ch
no jack sense but mic -> options snd-hda-intel model=3stack-6ch-dig
jack sense no mic -> options snd-hda-intel model=6stack-dig-demo
no jack sense but mic -> options snd-hda-intel model=acer
no jack sense but mic -> options snd-hda-intel model=acer-aspire
jack sense no mic -> options snd-hda-intel model=eapd

Could you please try installing the package linux-alsa-driver-modules-2.6.32-22-generic from the Ubuntu Audio dev PPA (http://launchpad.net/~ubuntu-audio-dev/+archive)?

Once installed, please reboot, and try to use your microphone again, making sure you removed the above mentioned model entry from /etc/modprobe.d/alsa-base.conf

I upgraded to linux-alsa-driver-modules-2.6.32-22-generic in the ppa, but this makes no difference. Sound is working, microphone is not. Jack Sense is also working.

cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on May 21 2010 for kernel 2.6.32-22-generic (SMP).

Anything else I can do?

If you are running the 2.6.32-23-generic kernel now, you need linux-alsa-driver-modules-2.6.32-23-generci. Easiest way to keep this updated is to install linux-alsa-driver-modules-generic.

Hmm... There is no package with the name linux-alsa-driver-modules-2.6.32-23-generic. But I am pretty sure you are referring to
linux-backports-modules-alsa-lucid-generic. So I installed that. But it makes no difference. Problem with the microphone still exists in the same way.

 cat /proc/asound/version

So I am not running the 2.6.32-23-generic kernel. Should I upgrade?

Some update upgraded the kernel but makes no difference.

Just upgraded to Maverick but still the same issue

+ upgraded packages from

linux-alsa-driver-modules-2.6.32-22-generic from the Ubuntu Audio dev PPA

but it still makes no difference.

Please let me know if you need additional information or if I can test something

Ok sorry for the confusion, but I am running

uname -a
Linux blingbling 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux

and

from the audio-dev ppa
