Do you have a Sega CD connected to your Genesis? I've read a couple times that the Sega CD causes problems when playing Knuckles Chaotix

Could it be a bad connection at the av connection? What type of video lead are you using?

i belive was the problem are on the 32X because genesis gets the 32x audio via the cartridge slot, so i need to know what pins on MD cartridge slot are designed for audio

IIRC the pins are B1 and B3. Not 100 percent sure.

I had this problem once. Solved the problem by opening the 32X, cleaning the flat cables and reconnecting.

This article shows the procedure I did:

I've done that myself, not for audio issues but for games not booting. It seems a common enough issue, so very worth trying
