I have 5.1 as well but I've found that I get better sound with the audio enhancements and hardware acceleration clicked 'off' What I think is what I've said in other posts, you just have to play with your sound settings. This is a re-occuring problem with IL2 but it's really up to your individual settings. I don't think anyone here can say do this and this and your problem will be solved. But the first thing I would do if I were you is un-check AE and HA and give that a try, good luck
