Nope, no /etc/asound.state file exists.  If I go to a Terminal window, I 
can play an MP3 file with mplayer just fine.  I have a /dev/mixer and 
/dev/mixer1 device node.  My audio settings in the frontend setup is:

Audio output device: ALSA:default
Passthrough output device:   Default
Max Audio Channels:   Stereo   Upmix:   Passive
x Enable AC3 to SPDIF passthrough   (x)Aggressive Sound (unchecked)
x Enable DTS to SPDIF passthrough   x Use internal volume control
Mixer Device:   /dev/mixer   Mixer controls:   PCM
Master Mixer Volume: 100
PCM Mixer Volume: 100
(x)Independent Muting of Left and Right Audio channels (unchecked).

Does anything in there have to change?  Should I change the Audio output 
device to /dev/dsp, for example?

Thanks,
Harry
