Automatically switch to connected Bluetooth headset and enable A2DP mode (ask for preferrence)

[Or Schiro]

Dear all,

I'm migrating this request from the eOS StackExchange community:

http://elementaryos.stackexchange.com/questions/1460/how-to-automatically-switch-to-connected-bluetooth-headset-and-enable-a2dp-mode/1825?noredirect=1#comment3768_1825

My request concerns the use of A2DP and automatic headset detection. The default state how A2DP is handled is as follows:

1. Enable bluetooth
2. Connect to paired bluetooth headset
3. Sound > Output > "Device for sound output" remains "Speakers - Built-in Audio"
4. Switch "Device for sound output" to bluetooth headset
5. Set Profile from HSP/HFP to A2DP

The desired state from a user perspective could be simplified as follows:

1. Enable bluetooth
2. Connect to paired bluetooth headset
3. Sound > Output > Device for sound output is automatically switched to the bluetooth headset
4. Profile is automatically switched from HSP/HFP to A2DP

I would love to hear your opinion on this request.

Thankfully,

Robert

Hey. I've found a script that will do what you want.

First you need to go to https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae#file-a2dp-py and copy the script. Then save it with the name a2dp.py and give execute permissions.
Now connect your BT headset, just connect it and run the script.

If right click > run doesn't work, open a shell in the folder you saved the script and type: python3.5 a2dp.py

My laptop, with Elementary OS already automatically switched it's sound output to my bluetooth headphones, but it didn't switch the sound controls yet (Speakers where still selected in the Sound settings). After doing the above it now automatically selects my headphone.
