I have the Turtle Beach Riviera, and it pretty much just worked without any
tweaking or .asoundrc files or anything.  The only thing I had to do was
fire up alsamixer and un-mute the appropriate channel (IEC958 if I remember
correctly.)  I can't remember what my specific settings were in the myth
frontend setup, but if un-muting IEC958 doesn't work for you, I can check
and post it.
