no sound with kernel-image-2.6.0-test9-1-386...deb

[Robin Gerard <robin.jag@free.fr>]

Hello,

I downlaoded the kernel-image-2.6.0-test9-1-386_2.6.0-test9-1_i386.deb
and I installed it successfully. Everything works fine, except the sound.
( I run also the kernel-image-2.4.20 and the sound is ok with this kernel )
My sound card is a sb.

First I launched modconf but no module was displayed.
 
I did: modprobe sb 
and I got:

sb: Init: Done
sb: Init: Starting Probe...
kobject_register failed for OSS SndBlstr (-17)

On the other hand I use rexima and when I run rexima I get:
rexima: couldn't open /dev/mixer.
(rexima works fine when I boot with the kernel 2.4.20)

Can someone help me to solve this problem ?
TIA.
