Comment 16 for bug 438318

Hey Manjo,

I'm not convinced this would be the most appropriate fix for this but in bug 389040 I'd found some patches for this sound card and codec that were from way back in Hardy (not sure why they were never merged upstream).

http://mailman.alsa-project.org/pipermail/alsa-devel/2009-May/016917.html

And it seemed to reference a patch to enable audio:

There also seemed to be a series of patches which followed to mute the speakers when the headphones are plugged in:

And then enable the microphone:

I'd forward ported the above patches to Jaunty and had positive feedback from testers:

Unfortunately trying to forward port once more to Karmic resulted in the built in mic not functioning any longer, so they're not perfect but may help.
