[mythtv] does Mythmusic audio output use myth library?

[James Armstrong]

I finally got spdif to work in mythtv using ALSA:spdif as the device 
with AC3 passthrough disabled. Mythmusic however does not work, giving 
me a Timeout opening device. A quick glance at the code makes me think 
mythmusic is doing its own audio processing, not using the newer ALSA 
direct library that mythtv uses. Can this be confirmed?
