That is correct. Once I recompiled CVS with ALSA support I got it to 
work only by turning off the AC3 passthrough off. I thought I read that 
it was supposed to passthrough the AC3 signal if present. I figured that 
if it was not present it would work as if it was not checked. With it 
checked I get no audio at all. I had my frontend turned off this weekend 
so I could not check to see if the AC3 option is also present on the 
mythmusic page. I had mythtv working with spdif, just not mythmusic.
