Comment 24 for bug 1064621

I tried the DKMS method, and it does work for me. About my last comment, it turns out the only reason that I didn't lose sound last time (on 3.5.0-17) was that I had enabled Dock Mic by accident (when playing with alsa-mixer) which caused a "hiss" sound to play all the time, and prevented the "few seconds of scilence" required to sensitize the problem. I muted the microphones and I lost the sound from internal microphone again.
