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.
