Bluetooth auto connect

the thing is your speakers should autoconnect, when paired, and with bluetooth audio switcher addon should switch output from alsa to pulse. I had noname headphones (bt4) that autoconnected to LE, using usb bt2.1 dongle. Now I upgraded headphones to sony bt5 and even they are paired, they won't autocnnect. I don't understand logic behind this autoconnect of bt device and if I should or could do anything to fix this. Same as you, I need to connect manually first, then output is switched by bt audio switcher addon.
