internal microphone on lenovo s10-3t netbook is not supported

Cancelled due to finding fix:

add to end of /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=ideapad

and reboot. Now it works.

I'm using Linux Mint 9 LXDE kernel 2.6.32-24 not only this options does not make internal mic works, it also makes external mic not working also. Perhaps something to do with LXDE?

songrit, plesae file a separate bug, as it appears you have different hardware to the origin bug reporter.

This is also fixed upstream, and can be installed by updating alsa drivers, as outlined here: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules. Note that once these updates are installed, the modprobe.d/alsa-base.conf edit is no longer needed.

Yes, I can confirm that the alsa driver fix works on lucid's 2.6.32-24-generic kernel. Now, internal mic and mic input both work and internal speaker and audio out work normally. And, nothing needed in modprobe.d. Great fix. Hope it gets backported to lucid for the long termers.

I tried running this on maverick, but:

1. linux-alsa-driver-modules-2.6.35-19-generic does not work with kernel 19-generic. The sound is not activated and the sound setting program shows no hardware.
2. kernel 20-generic has no linux-alsa-driver-modules-2.6.35-20-generic so could not be tested
3. linux 2.6.36-999-generic from the ubuntu kernel testing ppa seems to work ok (both internal and plugin mic and internal and speaker out plug) .. do you know if the 2.6.36-999 already has your alsa patch work done? If so, then I'd say it confirms that it works.

Yes, the 2.6.36 kernel series has the patch for your hardware included.

As for maverick and 2.6.35-20, there is not yet an alsa modules package built for that kernel. I am not the one responsible for getting that sorted, however I will chase that up today, as I have several other bugs that need attending to from others, where that alsa modules package is needed for testing.

There seems to be an error in version 2.6.35-22-generic because sound fails. Trying to load the module results in:
