consistent problem with pcm0 audio

I am using FreeBSD 5-STABLE from Feb 23rd with an onboard VIA 
VT8237/Avance Logic ALC200 sound controller. Periodically, 
sound will stop working. I will get the last note (sound
packet?) repeated over and over until I close the program. Any
further attempt to play a sound will cause the same note to be 
repeated. I am not able to reload the driver. Correct sound is 
restored when I reboot the computer.

This has been happening for awhile and I am not certain if it
was introduced with any particular update.

I am using ACPI. I don't know if this also happens without ACPI.

I also get a message on the console like this when the error 

	pcm0:play:0: play interrupt timeout, channel dead
