thanks for the thoughts so far, I do want to clarify the vox issue:
Other people can hear me talking, but I can't hear other people talking.
Another thing:
If my head if pointed forward in the cockpit, weapons fire is muffled, but if I turn my head to left or right, I can hear the weapons fire at normal volume.
I've ran through all the sound settings in AH, and all of them seem normal.
Any more help you folks can give is much appreciated.
