I believe I've solved the missing 3d sound issue with 9.04. It's not actually a bug as
I suspect, but rather a feature. I found that
after I installed 9.04 my 3dsound option in
the control strip was there, but grayed out.
However, if I placed a CD in the DVD player
of my sawtooth g4 the option reappeared. So
it does appear to only affect CD audio. I
believe this is solved.
