Comment 72 for bug 477226

I second Graffecke.de comment regarding the microphone: when using linux-alsa-driver-modules-2.6.31-20-generic from ppa:ubuntu-audio-dev/ppa, the internal mic (and possibly external also) does not work.

Many thanks to all and especially to Luke who seems to have spent a lot of time working on this issue.

By the way, a very inelegant and temporary fix for all these problems is to buy a USB sound card on ebay for like $3 and plug the headphones on that. Pulseaudio volume control will definitely let you switch away from the speakers with that setup..
