"No sound from applications" does not tell me much. Do the applications think they are playing music, and you simply cannot hear anything? (i.e. playback time advancing, ...). Is your sound card properly detected and appears in pavucontrol? Have you checked if playing around with "alsamixer -c0" in a terminal helps fixing the issue? if so, which control did you have to change?

Comment 5 Brent R Brian 2009-08-24 11:06:16 UTC
Thanks for the ideas ... I need to put this on hold until I can get it to fail again, I ran the alsamixer command and the sound is working fine, but, the last boot was also after more updates ... so I don't know which fixed it at this point.

I don't feel the results mean anything at this point.
