I don't think this is a problem with the card or the volume.  I see
this a lot on FreeBSD, since 4.8.  Matter of fact, I just tried playing
a wmv file with mplayer, and got no sound.  It was working fine
before.

Every once in awhile my sound just disappears.  Now, even a simple
waveplay command acts like it's doing its job, but nothing comes out.
Catting a .au file directly to the /dev/audio0.* devices just
announces that the device is busy.

The only thing that brings the sound back is a reboot, which
isn't an option I really like.

The card on this particular machine is an onboard Intel 5.1 sound
chip.  How the heck am I supposed to reset these devices?  There's
nothing in the handbook or FAQ that I could find.
