Excellent initiative, thanks!

The tree as of today, is now also available for easy testing for Ubuntu 
users: Just download and install 
http://people.canonical.com/~diwic/temp/alsa-hda-dkms-viacleanup_0.1_all.deb 
(works at least on Ubuntu 10.10 and 11.04), reboot and test.

I have tested the new driver code on a machine here, and automute does 
work. There is however no enable/disable automute yet, as Realtek has. 
There are no input jack devices either (i e those we're debating in the 
other thread).

On the input side I notice a minor thing: "Front Mic Playback Volume" 
has an unneccessary index on it. Well, the Front mic is actually an 
internal mic, but that's BIOS lying to us, I guess.

Otherwise it seems to work fine here, so well done! :-)

Alsa-info for the machine I have here will follow shortly.
