Comment 39 for bug 477226

Ok, I have packages with patched alsa drivers ready for testing. You can fetch them from my PPA, ppa:themuso/ppa for both karmic and lucid.

For karmic you want to install linux-alsa-driver-modules-2.6.31-19-generic, and for lucid you want to install linux-alsa-driver-modules-2.6.32-12-generic. Please remove any existing version of these packages you have installed, before you install the packages from my PPA.

Please test that connecting headphones mutes the internal speakers, and if you can, please test that connecting an external microphone to the microphone jack stops the internal microphone from working, and allows your external microphone to work. When testing, please make sure there are no lines related to snd-hda-intel and a model= parameter in your /etc/modprobe.d/alsa-base.conf file, or any other files in /etc/modprobe.d. I.e lucid users, there should be no snd-hda-intel lines in /etc/modprobe.d/alsa-base.conf, and karmic users, please make sure you don't have a model= parameter on the line mentioning snd-hda-intel in /etc/modprobe.d/alsa-base.conf.

Please report back with your test results, once you have installed the above packages, checked /etc/modprobe.d/alsa-base.conf, and rebooted. If people come back with positive tests for both microphone and headphones, then I will send the patch upstream.

Thanks in advance.
