[mythtv-users] I've lost audio in Video and DVD modes

I have a standalone mythtv box running FC1, 2.4.22-1.2188.nptl ATrpms 
kernel, with an M-Audio Audiophile 2496 sound card (audio via ALSA). 
Everything was working beautifully until recently - now I'm not getting 
audio when trying to play videos or DVDs.  However, audio is fine on 
live and recorded TV, and when playing music via myth or xmms.  I also 
tried playing some of my .mpg videos outside of mythtv, in both mplayer 
and xine.  No audio.  I've re-run alsaconf to no avail, and played with 
every setting in alsamixer and envy24control.  And as of tonight, 
mplayer crashes when I try to play a video via mythtv.

Below is output from mplayer after starting mythfrontend from the 
console, and trying to play a video.

Any help is appreciated - thanks.
