Did as advised: commented out the slave.pcm "digital" and removed the
comment for slave.pcm "dmix-digital". I then made the change in
MythTV from "ALSA:digital" to "ALSA:dmix-digital" for the "Audio output
device". Rebooted the machine but still no joy. I'm able to get sound
out via the analog output if I change "Audio output device" back to
default of "/dev/dsp".
Please help. This ALSA to SPDIF is making me going crazy.
