I don't need anything more than good stereo playback. Which is why I really
miss my SB64, but I can't pull it out of my old machine and put it in here,
because, of course, this machine has no ISA slots. I was hoping for
something at least as good as an ISA SB64 that I could slap in a spare PCI
slot. And I don't like PCI sound cards any more than you do... there were
some things that ISA slots really did well at, IMHO: sound cards and modems
(for those of us who don't require $40000 SB Audigy 2 platinum uranium pro
performance plus blah blah sound cards ;-)

My experience with PCI modems (not that I need them, just that I've had to
help friends with them) is that they're quite dodgy as a rule, and my
experience with the only PCI sound card I have has left me less than
impressed.
