Not necessarily.

Instead of removing the 16bit DMA setting, try changing it to 7 or something.

Assuming you had your old SB working on DMA 1, try playing in 8bit mode:

mpg123 --8bit file.mp3

assuming you use mpg123 to play mp3's.

This should use the 8bit DMA instead of the 16bit DMA.  If you don't have
any crashes, you know it's a problem with 16bit mode.
