Sound Card Driver on DELL D630?

["Michael Yang" <michael.yxf@gmail.com>]

Hi 

Any body has installed Debian Lenny/Sid on DELL D630 (T7250)?
I hit a problem on installing alsa package for driver of sound card.
It seems doesn't work and I can not startup alsamixer.

Is there an extra steps to configure the sound driver on this laptop? I have it working on my PC machine.

Your information are really appreciated.
Or can anybody direct me to any resource I can refer to?

Thanks  a lot
Michael
