Try reinstalling it with modconf. Also navigate to here Select kernel/sound/oss modules and go to

sb - 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support

and add this module for added soundblaster support.. I also added the i810_audio for further support. I don't know if they will help but you can give it a try. There are also modules that you can check out.
