I have an ESS AudioDrive with an ES1868F chip that I am using in a 486 dx2 66 build, with dos 6.22. This is a great card overall and works really well in most games
However, I am experiencing severe glitchy noise in some games, to the point of them being unplayable. To be clear, the audio works, it just has an overlay of these weird noises. Here's a video showing this in action:
That's x-com/ufo showing the issue, but some other games do as well, such as Psycho Pinball. And to be clear, lots of games work fine, like Doom, Wolfenstein, Raptor etc.
I have tried both the drivers on vogons, as well from Phil's computer lab. Changing irq, interrupt and isa slots have no affect. Anyone know what could be going on?
Uploading pic of card for reference. There are some jumpers on the card that I haven't touched, no idea what they are for. I understand some of these cards have a built in amplifier that can be disabled, but I doubt that's the issue.
