I have the same problem if the f18. It is only BRA or ATC calls that cause this. I can hardly make out what they are saying the static is so loud and there is no way to turn it off. The mission voice sounds when playing MP sound fine as do other players using SRS. It starts to give me headache after awhile then is just annoying as hell. Please fix this asap. This has been happening for awhile for me now.
