[mythtv-users] SPDIF howto? C-Media card

[Mark Hutchinson]

Beating my head against the wall here.
C-Media based card with SPDIF out.
Just wanting to get this working.

In Mythfrontend, audio setup, what is my device?

Here is some output.  I am not sure how to test it from command line.
I have the SPDIF connected to some speakers with the optical, but cant  
get any sound out.

aplay -L
