Thanks! If there's anything else I can provide to you (like a dxdiag or whatever), just lmk. I'm not sure how to use 32 bit sound drivers though -- I'll poke around here and see if I can find out how.
Update: tried to install the 32 bit drivers for my system but it wouldn't let me (I guess since Win 10 is a 64 bit OS), so I'm clueless otherwise. Sorry. :( That said, I'll continue to play the demo and just have the music off -- alas!
