I think the drivers know about the CDROM. Question: Can you mount a CD9660 filesystem on the CDROM drive? If so this would mean that the ATA/ATAPI drivers are not the problem. It would then be the case that the problem is with your soundcard: If you look in LINT which can be found in /usr/src/sys/i386/conf you will find entries about various bridge drivers for sound cards. There is a driver called sbc that supports SoundBlaster, ESS, and etc. It also gives an example entry for a soundblaster non-PnP isa card. You will no doubt have to modify the port, irq, drq and flags entries to correspond to your card. See the manpage pcm(4) and sbc(4) for a discussion of these entries. After you decide on the appropriate bridge driver, you need to make a new kernel. See the handbook for this.
