Alright, so I managed to solve this issue on my own. The following are the steps I, as an absolute beginner, used to connect my Airpods via Bluetooth:
Step 1: Open terminal and type: sudo apt install nano
Step 2: Now, on a new terminal line, type:
sudo nano /lib/systemd/system/bluetooth.service.d/nv-bluetooth-service.conf
Step 3:
Replace this line:
ExecStart=/usr/lib/bluetooth/bluetoothd -d --noplugin=audio,a2dp,avrcp
With this line:
ExecStart=/usr/lib/bluetooth/bluetoothd -d
Step 4:
Press Ctrl + X, then Y, then ENTER
Step 5:
sudo apt update
Step 6:
sudo apt install pulseaudio-module-bluetooth
Step 7:
sudo reboot
Final Steps:
Go to Bluetooth setting, then add new device, after sucessful connection, open up sound settings, select play sound through headphone: airpods pro, and change mode to HSP/HFP
Best regards,
