"Remember last movie position" - problem with Digi

I've got the following problem: when the option "Remember last movie position", which I personally find *very* useful, is enabled and I restart BSplayer, it plays the video from that position where I closed the player down. However, there is no sound... the really freaky thing is that after that I have no more sound AT ALL. Not with other files or players, I even tried games (OpenAL/DirectSound) and it just didn't work. The only thing I can do to fix the problem is reinstalling the audio drivers... if I leave the option enabled and start BSplayer again, the same problem occurs again.

Any ideas how to fix this, or where that error could come from?
