I did the upgrade and a reboot but the speaker still did not auto-connect. Then I did a manual connect and turned off the speaker again. After that the auto-connect worked. Also the second squeezebox instance was started automatically. But I don’t hear any sound. Squeezebox server shows that it is playing something on the bluetooth output, but the SB Blaster stays silent.
Bluetooth-Speaker is not active and I don’t have anything special installed (only what you can configure through max2play).
