Well it only occurs in the german subs, when playing standard TMO or anything else its just fine (in all US-subs it's correct), and on the deck it's fine too, its only while beeing in the control room (IXd2 and II in Om, havent looked into other subs yet) that the sound is turned around. The depth control is on the right, the TDC thing is on the left, to the front is the compass and engine controls, but still the engine sound is coming from that direction, so I cannot be mistaking this, right? In TMO nine delta two the dive angle has also been fixed so the engine sound is clearly coming from the front hehe. Thought this "problem" was known for sure, but if none of the greater mods ever fixed it (Om and TMO9d2) i just assume its hardcoded Ubisoft fubar.
Still, if anyone ever fixed this or knows any solution, please let me know.
And yes, that speaker config problem was well known to me since the early years when i got into gaming. "What? Left? Right? NO!"
