I've been plagued with this problem for the last week or two now. 
Constantly upgrading, tweaking, in the hopes of finding relief, but so
far, none.

pcm0 will work fine for a while, then suddenly, any further attempts to
use it generate the following:

Jul 13 23:31:18 dolphin kernel: pcm0:play:0: play interrupt timeout,
channel dead
Jul 13 23:31:49 dolphin last message repeated 10 times

Madplay, mpg123, etc. will start, play a fraction of a second's worth
of sound, and then exit.

This continues until a reboot.  The device is completely unusable until
then.

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Nvidia nForce3> at io 0xe800, 0xec00 irq 10 bufsz 16384 
(1p/1r/0v channels duplex default)
