I had this problem in 9.10 as well and restarted alsa all the darn time.  I
am using 10.04 now and just noticed that i can fix it by just toggling the
mute in alsamixer for the master audio.  That's right, just mute and unmute
and viola.  I am using SPDIF as well.  Something happens in myth when
changing between live TV, recordings, or mythmusic.   I use all three all
the time and have to keep alsamixer open in another window for toggling.
Hopefully we can find a fix soon because it's just plain annoying.  ;)
