I've installed the patch to get rid of the horrible screeching high pitched noise in Iona's dungeon, and now ALL dungeons have the noise, even the ones that didn't previously.
I can't play the game at all now. My save prior to the noise starting is so long ago that I have no intention of going back that far.
I have run a dxdiag but for some reason I can't paste it in here, so I can't give any further information. I'm running XP
I have the exact same problem. I have headphones, so whenever I go into a dungeon, I take the headphones off - but it's seriously wrecking the experience. Even the Divine Ritual has it so what should be a dramatic moment is wrecked.
In my case I have all the latest drivers direct x 9.0c, windows XP, service pack 2, latest sound/graphic drivers. Does anyone know how to stop the screeching?
