Just tonight discovered my 3-5 AES has reversed headphone audio.


I have seen mention to other revisions with this issue, but supposedly 3-5 models have correct headphone output. However I just again checked and mine is most certainly reversed.

What is the fix for this?

Could always cut the traces to the L and R channels and reverse them by soldering a bridge from before the cut trace to the L and R legs in the right orientation. Thats probably the cave man approach though.

SNK's fix on 3-6 boards consists of swapping the legs of two resistors:

The same can be done on 3-5 boards but I find it odd that the lines are reversed as 3-5 and 3-6 differ exactly in how the traces are routed to the two resistors.
