CMI8330 sound card on freeBSD 4.8

[TintaLiviu]

Hello,

I'm trying to configure my CMI8330 sound card. It is not onboard (so

options PNPBIOS[\code] I think is out of question).
I've tried to configure it: first I've added to the kernel configuration file:
[code]
 device pcm
[\code]
After compiling the kernel:
[code]
cd /dev
sh MAKEDEV snd0
[\code]
When I'm trying to listen one .mp3 file I receive:
[code]pcm0:play:0: play interrupt timeout, channel dead[\code]

I've tried also:
[code]
device pcm
device sbc
[\code]
The same result.

To help you better understand the situation I will add some command outputs:
[code]
bash-2.05b# cat /dev/sndstat

As you can see irq 11 is not used. 
I've also checked to see if other application is using the device, but no one used it.

Help will be very much appreciated,
  Liviu.
