Hi.

Apologies if this has been posted already.

After about 10 minutes of using my sound, it stops working.
My card as reported by the kernel:

Mar 27 14:15:09 mct12 kernel: ad1848/cs4248 codec driver Copyright (C) by
Hannu
Savolainen 1993-1996
Mar 27 14:15:09 mct12 kernel: Found OPL3-SAx (YMF719)
Mar 27 14:15:09 mct12 kernel: <MS Sound System (CS4231)> at 0x534 irq 5
dma 0,1

After a bit of use (10-20 minutes xmms etc) I get a lot of these error
messages whenever I try to play anything:

Mar 27 15:38:30 mct12 kernel: Sound: DMA (output) timed out - IRQ/DRQ

etc etc

All the sound drivers are modules...

Linux mct12.nettas.telstra.com.au 2.3.99-pre3 #2 Mon Mar 27 09:48:20 EST
2000 i686 unknown
Kernel modules 2.3.10

lines from modules.conf

options opl3sa2 io=0x220 mss_io=0x530 irq=5 dma=0 dma2=1
options sound dmabuf=1

Any suggestions? More info can be provided if required.
Once this has happened I can't remove any of the sound modules (they're
all in use) and a reboot is the only recourse. This all worked fine in
2.2.x

I can provide my .config or System.map if requested...

On another note I've already seen discussed here...

[tim@mct12 ~]$ asdf
asdf: Command not found.
[tim@mct12 ~]$ ipne
/usr/sbin/ipne: Permission denied.
[tim@mct12 ~]$ ls -la /usr/sbin/ip*
ls: No match.

Some things report Permission denied, others report correctly not found.

Thanks,
