Quoting Bart Schaefer barton.schaefer@gmail.com:
As I mentioned on a thread about flash-plugin a few days ago, I'm having trouble with my sound device getting "stuck" and thereby causing problems for anything that accesses it, like video playback.
Rebooting the machine "fixes" it for a while, but it's unpredictable for how long -- sometimes months go by without it recurring, sometimes it happens every couple of days. Right now I'm in one of the latter phases.
Any suggestions on how I could reset the controller without having to reboot? (Or suggestions for where else I might ask this question?) Below is output from "lshw" for the audio controller, and "lsmod" for the sound modules that are loaded. This is CentOS 4.7.

I have similar problems in CentOS 5. I disable and enable the flash plugin in firefox, and it seems to be corrected. My problem may be slightly different, but this is how I 'fix' the problem.
