This is just a QoL thing and will be much appreciated if someone helps me.
I have done the following to have my Bluetooth headset start in A2DP when I turn it on as I windows but what works is having it on and connecting it via the Bluetooth indicator manually, then it auto connects to /etc/pulse/default.pa configuration:
Note: Even without the auto-connect configurations it does auto connect if I turn it on while the session is logged.
/etc/bluetooth/main.conf
[General]
Disable=Headset
AutoConnect=true
MultiProfile=multiple
load-module module-bluetooth-policy auto_switch=false
and
/etc/pulse/default.pa
set-default-source echoCancel_source
set-default-sink a2dp_sink
