[alsa-devel] help with idt 92hd206 codec for intel hda?

[Greg Zornetzer]

Hi Takashi, Steven, et al,
My apologies for not getting back to you earlier.
I applied the short patch to the hg-20080502 snapshot.  That seems to have
done the trick.  All of the different analog output channels are now
available, as well as a bunch of input channels.  I only tested output, but
that seemed to work. I will hopefully be able to test the inputs this
weekend.  Given the discussion that I saw, it looks like I won't bother with
the digital output.
Thanks very much for your help on this.
-Greg
