The SB16 does have this weirdness with the driver.  I was lead to believe
that it was a problem with the way it does DMA differently than the normal
cards.  Apparently, it is a solvable problem, as some have done so, but
then lost the code changed they made.  I wish I had the time, resources,
and brains to fix it myself, but for now, I am just waiting for some knight
in shining armor to do it.  :)

Although, I just had a stranger problem...  I played some .au files from a
web page, and got nothing but awful static.  They were from the JDR
microdevices 'mystery sounds':
