Default [help] pimeta ground buffer heating up

I have been staring at my board for a long time, but I have no idea what is the problem, or what could be the problem.

I've assembled my whole pimeta according to tangent's guide, but there are two problems that occur:

1) the ground buffer BUFG heats up when there is an input signal. It heats up faster the more i turn up the volume
2) the right ear has no sound output, but it grows very warm.

I've already pretty much killed the right ear, but I dont mind since its a test pair of headphones.

I've double checked my soldering on the board, and I'm pretty sure that there are no short circuits anywhere. Does anyone have any ideas of how to debug/what the problem might be?

thanks very much
