Get a C-Media chipset based sound card.
bluestringer
I use the onboard sound on my Abit NF7-S. This is the version with
the Dolby Digital Encoder. I use the spdif out to my receiver and
enable the encoder, which sends the DirectSound stream as AC-3.
When I enable 3d sounds in NR2003 there is a LOT of reverb, like you
are in a cave that is inside an aircraft hanger or something. Anyway,
to make it go away, I have to go to the options menu, turn off sound,
return to the main menu, go to the options menu again, turn sound back
on. When I click to turn sound back on, everything hangs for about 5
seconds, then after that the main menu appears and the reverb stops.
I haven't tried any other games, so I dont know if this is NR2003
specific, or has to do with the NF2 audio.
HTH,
