I'm having this same problem with pcm on a sony vaio Z505SX (has the neomagic
chipset). Attempting to play an mp3 file with mpg123 results in "pcm0 play
interrupt timeout, channel dead" and then /dev/dsp is locked. Attempting to
play short .wav files results in looping of a half second segment of the .wav
file for a long time...then sound stops working.

I'm running STABLE (RC):

FreeBSD dbm.wireless.net 4.1-RC FreeBSD 4.1-RC #0: Thu Jul 20

on that box.

Is this a bug in the pcm driver, or is this the result of poorly supported 
hardware (specifically the neomagic chipset in the vaio)??

Any ideas?
