I have recently lost sound and can only get it to run if I stop
Thunderbird. It has always worked until about a week ago.
When I run "system-config-soundcard" and click on the test button I
hear nothing and get the following error message:
amixer: Unable to find simple control 'PCM-2',0
amixer: Unable to find simple control 'DRC Range',0
Usually, but not always, closing Thunderbird will cause the sample chord
to play as expected. To run a .wmv in mplayer I must first close
Thunderbird or mplayer will report an error with sound.
I tried removing Thunderbird and reinstalling it from the rpm but saving
the old Mail files to keep the mail filters and messages. That seemed
to restore things to normal but within a day sound was out again.
I don't know how to troubleshoot this. I guess I can live without sound
but it should work.

Any thoughts appreciated.
Thank you.

You didn't mention which card you use,if a SB Audigy, check <control

similar problems for me.
