Originally posted by Unregistered I have an AC'97 Sound Card that doesn't let me play old DOS games,...

Actually, it's your operating system that won't allow audio for DOS programs. There is no DOS in Win2000. You have a command prompt that has a certain amount of compatibility with DOS, but it's not DOS. VDMSound is an audio card emulator that redirects the DOS audio to the sound card through the OS (DOS programs normally bypass the OS and hit the hardware directly).

... and that's why I downloaded VDMSound. I read the readme file and everything, and I ran Duke3D with VDMS on, but it still doesn't work.

Did you follow the guidelines for BUILD games as listed in "Problem Children"? All BUILD games have additional problems in NT, especially NT4 & Win2000.

In the setup, which sound card/IRQ/8bit DMA/16bit DMA/Address should I set???

VDMSound has default settings of Address 220, IRQ 7, DMA 1 (8Bit), DMA 5 (16Bit) and is equivalent to a SoundBlaster 16.

... my DOS window gets laggy when I TEST my sound, anyone has any advice on this?

Don't run it in a Window, expand it to full-screen.
