i was able to get the sound working on an aftermarket one but i think the little connection points on the 3.5mm plug are different then the 6900's so what i had to do was actually just plug the adapter in part of the way... or push it in all the way and pull it out a bit till the sound came back....

once i figured out where it was i slipped a small sized nut over the plug and glued it, so now i push it in all the way and its where its supposed to be.
