Hi,

I am trying to use a 3Dfx Voodoo1 card in a 750mhz Pentium system running DOS 6.22 or Windows98, and have tried both an ISA Sound Blaster Pro 2 and PCI Hoontech SoundTrack Digital XG sound card. Whenever a Voodoo game is running, the sound cuts in and out several times a second and is garbled and distorted.

I have tried both enabling a PCI "delayed transaction" option in the BIOS, and also adding SST_FASTPCIRD=0 in autoexec.bat with no effect.

Can anyone suggest what I may be doing wrong?

Thanks

Hi,
When you write "a Voodoo game", do you think Glide and D3D game ?

Hi,

I mean a 3Dfx Voodoo1 hardware accelerated Glide game rather than a software rendered game. The audio is fine with software accelerated games. I have not tried any D3D games, as I am only worried about getting Glide games working.

Thanks

After some more testing, I've found that the distortion does not occur in all games, but in DOS glide games such as Carmageddon and Blood.

Both of these games have good audio in software rendered mode.

Some of the games with built-in Glide support such as Whiplash and Archimedean Dynasty have no problem, in spite of being hardware accelerated.

I don't know if the problem may be due to a specific version of the Glide ovl, my motherboard chipset/bios settings, or something else. So far I have tried four different sound cards (ISA and PCI) that all have the same distortion, like very rapid stuttering that speeds up and slows down, probably corresponding to CPU load or bus activity.

Thanks

...and I give up. I put in the Voodoo2 cards and Carmageddon runs without the stuttering audio. It would probably be easier if I could resolve the Voodoo1 problem, but this will do.
