I have i810 motherboard with onboard sound card. When I play some sound file with play for the first time after the boot, the kernel module snd_pcm_oss crashes. The file is played normally. It happens when closing the /dev/dsp0
After that the /dev/dsp0 can not be opened. After that any program that tries to opne /dev/dsp0 sleeps on open(/dev/dsp0,...).
Here is the Oops:

play uses sox which version is 12.17.1
The kernel is 2.6.0-test6. With 2.6.0-test5 this dos not happpen. When i use aplay this does not happend.

Here is the out from lsmod:

After the crash snd_pcm_oss and snd_intel8x0 are used.

If someone needs additional information I will be glad to help.

I have i810 motherboard with onboard sound card. When I play some sound file with play for the first time after the boot, the kernel module snd_pcm_oss crashes.

I can confirm this, but with other hardware, namely:

karpfen:/usr/src/linux # lspci -v

The symptoms are: playwave does not work. xmms works, but much too slow.

The relevant part of dmesg is this:

via82xx: Assuming DXS channels with 48k fixed sample rate.
Please try dxs_support=1 option and report if it works on your
machine.
PCI: Setting latency timer of device 0000:00:11.5 to 64
ksysguardd: numerical sysctl 7 2 1 is obsolete.
