[mythtv-users] Tips for sound in xubuntu?

[Dan Armbrust]

I have myth configured to output sound via spdif to my stereo - and it
works fine, more or less.

But recently (and I'm not exactly sure when) the entire OS stopped
outputting any sound.  Can't get sound from VLC, Firefox, etc.

I'm running xubuntu 11.04.

Anyone have any tips?  It still seems like it is trying to output
sound - if I mute the output via the mixer, my tuner changes modes.

I've looked through the various mixers I can find... nothing is muted,
pcm is enabled, etc.

Could the myth backend be locking the sound hardware?  Guess I can
check that tomorrow.  Or is it purely an OS config issue?

Thanks
