I stand corrected. It seems on this one, the GUI widget uses a
different name from the database setting (the database setting is
"PassThruOutputDevice"--I guess to save all of 3 bytes in the
database). They were close enough I didn't notice the difference first
time (or second time) I looked (I had to break things down to find the
difference).

Default means to use the value you've set for the audio output device
(i.e. Myth's default, not ALSA's default).
