>Organization:
>Environment:
FreeBSD 4.4-PRERELEASE #25: Tue Aug 14 09:50:27 CEST 2001
with pcm enabled
>Description:
Since the pcm MFC on August 1st various applications have problems.
Here is a summary of the observations taken from -multimedia:
pcm0: <SB16 DSP 4.16> at io 0x220 irq 5 drq 1:5 (1p/1r/0v channels duplex)
- mtv (linux) audio doesn't work, the console says:
pcm0: play interrupt timeout, channel dead
- in mxaudio the progress slider runs like hell; a 4 minute
song is processed in 4 seconds. No audio appears..
- sox produces a short blip as though the sample is playing too fast
- mpg123 works!
pcm0: <Aureal Vortex 8820> at memory 0xf4000000 irq 10 (4p/1r/0v channels duplex)
- same with mtv
I assume the list isn't complete; it just lists the problems seen
until now.
>How-To-Repeat:
Update to a recent 4.4-PRERELEASE and try some of the above combinations.
>Fix:
I replaced /sys/dev/sound completely with the version before august 1st
and created empty pci/ich.c, pcm/vchan.c, pcm/sndstat.c and pcm/feeder_rate.c
files so I didn't have to mess around with sys/conf/files :-)
