I think he means one and the same (Aux cable of the sound system in the headphone jack and not the Dock's line out jack).
Not an optimal solution, I know, but given that if a 4.1.1 ROM was available, you wouldn't want it, as it is affected by the nasty Heartbleed bug. (4.1.2 and up is okay).
But maybe you could try older, that is, Entropy's CM9
(4.0.4). The ICS/JB versions were developed so fast that there was too little time to squash the bugs, and CM9 is supposedly a prime example of that, but four your needs, it's worth a shot.
