Thanks, but it still does not work reliably.
Here is what I did:
– connected ethernet
– disabled WIFI
– turned on Bluetooth speaker
=> speaker connected, max2play started second multisqueeze instance
– started radio stream on squeezeplay bluetooth channel
– turned speaker off
=> bluetooth connection turns red in max2play GUI; bluetooth multisqueeze instance stays; squeezebox continues to stream (seconds count up)
– turned speaker on
=> bluetooth connection turns green; squeezebox continues to stream; no sound
– stopped bluetooth squeezebox instance
– started bluetooth squeezebox instance
=> sound starts playing on speaker
So the problem seems to be that mulitsqueeze does not stop the bluetooth squeezeplayer, when bluetooth is disconnected.
