Settings of bluetooth earphones

Why the settings cleared on every time I connect my Bluetooth earphones? Every time I connect I had to go to my Bluetooth earphones settings in “Sound” to change the profile from “Headset Head Unit” to “High Fidelity Playback.”

Also when I change the microphone input from “Internal Microphone” to “Bluetooth Input”, the playback profile changes back to “Headset Head Unit.”

Why is this happening?

See if using Aravisian’s method also saves your settings:

I already autostart Bluetooth using sudo bluetooth on in startup applications. My problem is with the audio profiles. They get switched on every connect. And how can I force the system to use bluetooth earphones mic when the bluetooth ear phones are connected?
