[mythtv-users] LiveTV & MythMusic - Just lost sound

[Brian Donaldson]

In addition to the optical audio cable I was using I added an analog audio
cable between my MythTV box and my receiver.  Now when I use live TV or
MythMusic I just have to push the button on my receiver to switch from
digital audio to analog audio.  It works now, but I don't understand why it
worked at first with just the optical cable.
