gnome startup : \"can\'t find /dev/sound/mixer\"

[freebsd]

Hello everybody,


I have FreeBSD 4.8 installed on an AMD thunderbird 800 and i am using gnome.
everytime i start gnome, i get the error message \"cant open /dev/sound/mixer\".
There is a Sound Blaster 128 Pro PCI installed in the box, but neither does /dev/sound
exist, nor can i spot anything that looks as if it could be a sound card in the output of dmesg.

a threat at linuxquestions.org [1] exists that seems to describe the same problem and someone claims the solution was to rebuild the kernel with soundcart support, but noone did further comment on that proposal.

is there no sound card support in freebsd 4.8 by default? do i have to rebuild the kernel?
or is there another solution to my problem?     

thanks for your annswers,

tim
