It's iec958 (not spdif).  Try moving your asound.conf and then start the 
frontend. I.e.

mv /etc/asound.conf /etc/asound.conf-bak

Also, aplay is likely to fail with iec958 (because you /must/ have a 
specific type of input for it to work), so test with mythfrontend using 
AC-3 passthrough and a recording that you know has an AC-3 stream.
