Allen,
  Yes you're correct, I want to route all sound through spdif.

I did not have an asound.conf and apparently this was my issue. Until
recently, I was getting by with *only* ~/.asoundrc. When I ran `apt-get
update` on my system to support mythtv SVN for hdpvr and VDPAU non-DTS audio
stopped working for mplayer and xine.

1. I created asound.conf as you suggested and removed  ~/.asoundrc.
2. `/etc/init.d/alsa-utils restart` did not help, so I rebooted.  Now xine
and mplayer both work for regular pcm audio.

I really appreciate you and everyone taking the time to post.

Al
