[mythtv-users] Turtle Beach Riviera /CMedia CMI8738 and optical SPDIF

That is great news! Hopefully I am skilled enough to replicate that
functionality on my system. To your recommendations, I have IEC958 output
turned on, I have no .asoundrc file and I have myth configured as you
described - which is what got me 2 channels in the first place.

A few additional questions:

Which Linux distro are you using?
Which ALSA version are you running?
Did you have to do any special config of the module or ALSA?
Did yours just work? If not, what things did you do to troubleshoot?

I am thinking that mythtv is not the problem, and that it is something in my
OS config that is the issue.

Sure.  This is my recommended card for optical out.  No funny .asoundrc 
needed.  Just set Myth for AC3 passthrough, turn on the IEC598 in the 
alsa-mixer and set your output device to alsa:default in Myth
