ATI SB600 on Compaq Presario CQ40-401TU

Hello all,

I am using FreeBSD-7.1-RELEASE on a Compaq Presario cq40-401TU. The sound's chipset is ATI SB600. It's luckily that FreeBSD supports SB600.

After loading the `snd_hda' module, I can play a mp3 file but I can hear nothing. I changed the volume to 100:100 by using `mixer'.

After rebuilding the KERNEL with sound devices in configuration:
Code: 
device sound
device snd_hda

I cannot access to /dev/dsp or /dev/dsp0.0

Code: 
# ls /dev/dsp
/dev/dsp
# echo sample sound > /dev/dsp0.0 
su: /dev/dsp0.0: Operation not supported

I got the same error (operation not supported) when using `mplayer'

Code: 
[AO OSS] audio_setup: Can't open audio device /dev/dsp: Operation not supported
[AO ESD] esd_open_sound failed: Broken pipe

Could you help me to install SB600 driver on my CQ? Thank you so much!

Regards,

PS: I have bought this laptop and I dont' intend to install Windows on it. I may have no sound, no webcam and no wireless :p
 
Below my /dev/sndstat:

Code: 
# cat /dev/sndstat
