SPDIF is limited to 2 channels when using PCM. DTS/AC3 is the only way to get multi-channel out of SPDIF. Unless you run ADAT, which is 8 channels uncompressed 24bit/48kHz, but I'm not sure that's supported in Linux.

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.
