thanks...  but it didn't work...

i have compiled the sound and snd_sbc devices in the kernel and load the
driver via the loader.conf.
kldstat says snd_sb8.ko is loaded.
the volume control doesn't work and i tried it with the default cd player.
the player works fine and it plays the cd but no sound is coming out of
the speakers....

any other ideas?

thanks again...
