I’ve been playing around with the max2play image and its plugins for a while and got everything running so far.

Let’s say I put the squeezelite-player to PULSE. So whenever I turn on the bluetooth headphone it would play through these automatically. And when these are not available ( turned-off ) it would use the PIFI DAC soundcard.
