Yep, that's correct.

It's on my TODO list to merge the two audio layers though.  I have been 
looking at RTAudio as a *really* nice way of doing this.  But it's Jack 
handling doesn't quite work for me.

Anyway, I have written a Jack output layer, and it makes sense to try 
and merge all these different audio output layers as far as possible, 
but it's not entirely trivial because Mythmusic uses some stuff which 
isn't in the main audio layer (eg larger buffers and an event system to 
supply the visualisations with the samples at the same speed as the card).
