device /dev/dsp can't be opened (No such device)

Hi i installed Slackware 8.1 on my Pentium MMX 233 MHz box
81 MB Ram Diamond Stealth II S220 Video Card and a Creative Sound Blaster 16 Sound Card
installing worked perfect ( had to select few as posibel packages because the installing hd is only 1.2 gb but i have an other hd 1 gb
wel i configured the X system had to use vesa as the drive nothing else would work not even the drivers in the driver list
after that i started booting into KDE looked beautifel ^^ then i got this error
device /dev/dsp can't be opened (No such device)

lsmod returned me:
Module Size Used By
soundcore 3236 0
pcmcia_core 40896 0
ide-scsi 7456 0

and psaux | grep `fuser /dev/dsp/`
returned me
root 528 0.0 0.5 1404 464 pts /0 5 21:57 0.00 grep fuser /dev/dsp (i wrote it down because i dont have internet on that box its just for music nothing needed to work besides xmms the mouse and the sound 3 out of 3 lol xmms dont work the mouse didnt work i worked hours on that and now the sound ^^)

I am not sure if the following might work on your machine or not but it works on mine.

make sure that the volume is what you want and the options are not off. if they are then click m for the ones you need.

If the above didn't work for you then try to load the module yourself
/sbin/modprobe soundcore

If nothing worked then try running, alsaconf, as keefaz sggested.
