Listen to a channel check file the same time on speakers and headphone. It seems that the left and right channel on the headphone are swapped. But only on the headphone. The same time the signal is coming from the speakers in the way it is supposed to be. I'm using a PI3b with a DAC2 Pro.
I tried this with MoOde and to be sure later with HiFiBerryOS, but the same results.
What can I possibly do to fix this? Hope you can help me on this one?
