Yeah, I guess I was saying that because I was happy you had asked a
question regarding sound - even though what I gave you was probably more
than you needed/wanted ;-) Sorry.

This does seem to have solved the problem, at least on initial testing;
after altering my frontend startup script to run "alsactl restore" prior
to calling mythfrontend, I haven't had any further problems with muted
sound so far. The box has been in use all evening so haven't tried a
reboot yet. Thanks very much.

Nope. Using "default" as the "Audio output" and/or the "Digital output"
did not work in any combination of device options (I tried at least 10).
The only one that works now is:
Digital Output: ALSA:iec958:{AES0:0x02} (why 0x02 now works, I'm not
sure, it didn't before, needed 0x06). All other settings as above.
Thanks for your help -
Bob
