Hello

I have a problem with the game sounds and i can't wrap my head around it.
First off, the sound in the breefingroom and on the flight deck is fine but when i fly, the flight voices and shooting sounds are warped and laggy and sometimes dont play at all. Sometimes it works sometimes it doesn't, without touching any of the setting. The strange thing is, that the music always plays fine and sounds good, no problem there, it is just the inflight voices and sounds. i tried to disable the hardware exceleration but it turns out that doesnt exist anymore in windows7. Any thoughts on that?

I appreciate your help.
