aplay of .wav failed:
# aplay -D digital2 bustin.wav
# aplay -D digital2b bustin.wav
# aplay -D digital2c bustin.wav
Looked in alsamixer:
# alsamixer -c1
"Item: IEC958 Output" was MUTED. Unmuted this and...
# aplay -D digital2c bustin.wav [WORKED!]
(This is card 1, device 2).
Save settings:
# /sbin/alsactl store
Note, that I later saved the mixer settings to a file with:
# alsactl -f /root/asound.settings.riviera store
Default location is /etc/asound.settings
Changed setup in MythTV (Settings->General):
Was: ALSA:digital
Changed to: ALSA:digital2c
WORKED!
