I'm having some very weird issues with my speakers. Music plays fine, but when I play a film I can't hear any speech from it. All that plays is the background noises in the film. I've tried a number of different players (VLC, media player classic and windows media player, but have the same problem with all). I have managed to find a short term fix for this, which is to change the speakers settings to only 2 speakers instead of the full 6. Magically I can then hear the speech. Has anyone come across this problem before? Any help appreciated.
