i´ve using max2play with the lastest update and after a wile of playing music with the channel correctly i put a test tone and i have the two channels swap…
i m trying to find and it seems sometimes pi looses connection during playblack and when the connection is restablished the channels are swapped. (i don´t know if is it or not) but is a very annoying but because it sounds bad when the channels are swapped.
