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

Well, when I first installed my distro, I managed to get the spdif to output
2 channels. I could only get two channels, unless i sent a raw DTS or AC3
stream for decoding on the receiver end.

Now, on after I reinstalled (changed from raid0 to raid5), I cannot get any
audio whatsoever (even via analog outs).

So there are really two separate issues now.

1) Getting audio to work.
2) Getting 6+ Channel audio via spdif.

Should I try applying these patches or should I try compiling ALSA by hand
instead of using the distro supplied package?

Also, after looking at the sigmatel patch for hda-intel, the 92xx chips are
limited to two channels via spdif... On my first install, I changed the
limit, and recompiled by hand. ALSA would then tell me that 6 channels was
ok, as opposed to throwing an error, yet I still only got two channels.

Ideas?
