I'm having an issue when I run CPUSPD. The program runs fine, but when I go to play a game after enabling my settings it hard crashes (and makes a loud buzzing noise on some games like Mortal Kombat 2) and I have to hit the power button. It has crashed with a dos4gw professional 2002 error and a stacks overflow error. But sometimes it doesn't say anything since it's just frozen. I've narrowed it down to the audio. Not all games do it, but most of them do. I disabled the audio drivers in the games and I can boot into them fine, but of course now I have no audio 🙁.

Also, they work fine when I run these same games in Windows 98 DOS prompt with CPUSPD. So it's just a DOS issue. Without CPUSPD enabled, they run fine in DOS with audio. Any ideas on how to fix this? I want to get CPUSPD working in real DOS since some games just play better in that mode. Sound card is Aureal Vortex 1.
