sb module only needed to specify dma=0 or dma=1.  What is this all about 
anyway?  One channel for recording?

I am NOT going to recompile my kernel to play sounds.  I got one ESS card 
working without all this.  I am way over my head already.

no soundlow?  no v_midi?

What is opl3?  Do I need that to make sb work?  I might try it, but it 
looks like something to do with midi.  

Thanks for the above and I think I understand why Ron avoided Vibra16.
