Win 98 CDRW/ sound problem after replace

I replaced a CD-Rom with a CDRW in a Win 98 system and also replaced the sound card with Sound Blaster Audigy and now both CDRW are recognized by the system and read disks, but I am not able to get the sound to work. I also disabled the onboard sound card on an Intel SE440BX-2 Motherboard in the Bios as suggested by the Intel website. and I removed the software for the onboard sound card. Any help would be greatly appreciated
