All of my ISA Creative sound cards work perfectly in DOS.  I don't know 
what your problem is with DOS synthesized sound.

Does the DOS diagnose program tell you the two DMA settings (low and 
high)?  For MP3 playing you need both.

To get synthesized sound in linux you also need to insmod opl3 io=0x388.
(use module opl3.o)

If you have an AWE (advanced wave effect) card there is no reason to use 
synthesized sound.  Use awe instead, it sounds much better.
insmod awe_wave io=0x620
(use module awe_wave.o).

One of our list members compiled and posted a Timidity packages to play 
midi files, with 'patches' that sound even better so you do not need 
synthesized or awe sound.

Did you try using dma16=5 instead of 0?  Zero may not be an acceptable 
setting.  (I think low dma can be 0 1 2, high DMA 3 4 5, but see what 
diagnose tells you).  Without the correct dma16, I also could not open 
/dev/dsp.

Can you listen to anything in BL3?

To listen to CDs, use workbone and you need to make a symlink
If your CD drive is hdc (secondary master)
ln -s /dev/hdc /dev/cdrom

To listen to mp3s you need /dev/dsp so try dma16=5

That sounds like a different problem.  I thought your problem was MP3s.
