[alsa-devel] Recent code changes for HD-audio on HG repo

[Tobin Davis]

I have some spare cycles to look into this over the weekend.  Please
send me the output from
http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh .
We can take this off-list and I can send you some test patches.

Thanks,

Tobin
