Hi,

I think, I have a big problem, and I hope anybody can help me. 


At first, my sound device:

Terratec Maestro 32/96 (16-Bit ISA PnP)



When no driver has been loaded in the kernel, FreeBSD 4.1-STABLE boots
with the following message
unknown0: <WSS> at port 0x534-0x537,0x388-0x38b,0x220-0x22f irq 5 drq
1,3 on isa0
unknown1: <GAME> at port 0x201 on isa0
unknown2: <CTRL> at port 0x538-0x53f on isa0
unknown3: <MIDI-2> on isa0
unknown4: <MIDI-1> at port 0x330-0x331 irq 9 on isa0


with "device pcm" in the kernel, FreeBSD boots printing:
pcm0: <CS423x> at port 0x534-0x537,0x388-0x38b,0x220-0x22f irq 5 drq 1,3
on isa0
unknown0: <GAME> at port 0x201 on isa0
unknown1: <CTRL> at port 0x538-0x53f on isa0
unknown2: <MIDI-2> on isa0
unknown3: <MIDI-1> at port 0x330-0x331 irq 9 on isa0


client1# cat /dev/sndstat
FreeBSD Audio Driver (newpcm) Sep 10 2000 20:40:36
Installed devices:
pcm0: <CS423x> at io 0x534 irq 5 drq 1:3 (1p/1r channels duplex)
client1# 


And now my problem ;-)

when I try to start playing an mp3 with xmms, I can hear the song. Now I
stop playing, and try to play again but, xmms said (I'm using the eSound
Output plugin, OSS does not work):

/dev/dsp: device busy

in my syslog file I can find  "pcm0: play interrupt timeout, channel
dead". Now I try find out which program is using my dsp:

client1# fstat /dev/dsp
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W
NAME
client1# fstat /dev/dsp0
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W
NAME
client1# 


Can anymbody help me fixing this problem?

O. Lehmann
