[sc1949]

This just started, was OK last time I used iL2, now reverberates as though I'm flying in a huge drum or barrel. H aven't changed anything IE mods for 2 days, and it was playing good until today. All sounds are working, just this hollow sort of sound just started. Any ideas, I think this was similar to when I first found AAA site, but not sure. Have 0.93 sound, use headphones only, x64 Vista, looks OK in Windows .
Thanks for all help in advance
