Game Crashes and flashing screens

[d64]

It seems now after patching to 2.0-cd I am having sound crashes again. I had these before but they were cured by converting the mp3 files to wav. I noticed that after the patch I had to replace the sound ini file again, but that did not help. I even moved all the mp3 files away to make sure the game is not playing them..

The crash is as follows, and it always occurs a few mins into the game, when I push a button, usually, or when some other sound is supposed to be played:
