Welcome to subsim, bowfin
I know it's a simple answer, but perhaps you're not facing in the direction you think you are facing while in the conning tower and control room. Could be that the interior models are rotated in the wrong direction, too (pure speculation there). Did the same thing occur in the stock game? I'm guessing it would because it doesn't sound like the kind of problem that could be caused by a mod. Is the left to right exterior sound orientation as you expect it while in the interior? Is it a full moon? Have we entered the twilight zone? (don't answer that question, I know I'm there

)
