Fantastic. All the sudden I have no sound

Couldn't get audio on my webcam working in guvcview the other day, now it appears something has slaughtered ALSA altogether. ?? When I run comand:

mocp DAEpl.m3u

I get

Can't load plugin libmusepack_decoder: file not found
Running the server...
Trying JACK...
Trying ALSA...
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
Trying OSS...

FATAL_ERROR: No valid sound driver!


FATAL_ERROR: Server exited!

Trying to capture a stream on guvciew gives me this:

Hi SecondComing,

I can't provide insight in the audio problem, but your colorful language gave me a smile on my face.

Cheers,
Cedric
