Hi,
   I am debugging a problem that seems to require me to reboot the machine
after it happens as Alsa cannot recover. I am wondering whether there is any
known way to script a complete Alsa restart, like I can do with networking
or other drivers, so that I wouldn't have to do this reboot?

   I've tried /etc/init.d/alsasound stop and then start. This doesn't work.
I've tried the stop/start with an rmmod of everything I can see in lsmod,
but this doesn't work either.

   I suspect that a big part of the problem is that the sound card itself is
getting into a state that the drivers and Alsa do not have the capabilities
to get it out of and possibly what's happening is the reboot fixes it via a
PCI reset operation.

   Can anyone recommend a method that might actually work? This is a bit
painful because right now a simple adjustment even in alsamixer requires me
to reboot the machine.

Thanks in advance,
Mark
