Doesn't seem to work for me.

Note that I'm talking about mythmusic here NOT mythtv. My TV sound comes out 
via my PVR-350.

I cant get mythmusic to accept anything ALSA!!

/dev/adsp works OK, but it will only play 48khz files. all my mp3s are 
44.1k.

I was under the impression that /dev/adsp was supposed to convert the 
bitrate if required.

DOH!
