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? -- Regards, Devin.
