Automatically switches A2DP/HSP/HFP when a microphone is needed in Linux and pulseaudio. Just run the installation script and you are ready to go!
pactl: The pactl executable should be available.ruby:>= 2.0.0should work. Tested with2.7.2pipewire-pulse: Optional if you are using pipewire.
You can use the provided install.sh in all distros with systemd and pulseaudio on them. If you don't have systemd then just running `bluez_pa_auto_switcher.rb'
after boot/login should work.
To install it simply run the following command:
bash -c "$(curl -sSL https://raw.githubusercontent.com/alisinabh/bluez_pa_auto_switcher/main/install.sh)"Or you can just clone and run the bluez_pa_auto_switcher.rb file manually.
You can edit the ~/.config/bluez_pa_auto_switcher/config.yaml file to change the configuration.
validClients: A list of application names to support auto switching for.
After changing configuration you will need to restart the service using systemd.

One of the most annoying things happened to me as a Linux user was setting up my bluetooth headphones. For audio playback it mostly works fine though.
The problems start to happen when you try to use the microphone. To use them you need to change the card profile to Headset Head Unit (HSP/HFP) and that should happen manually.
(For example using pavucotrol GUI or pactl set-card-profile in terminal) But like MacOS and Android I wanted it to happen automatically in Linux too.
I found this tool bt_pa_auto_switcher but I wasn't able to get it to work :(
But after reading the source I decided to re-write it since it looked pretty simple. Just watch for pulseaudio events with pactl subscribe and change the card profile whenever a valid client asks for input sinks.
The project is heavily inspired by bt_pa_auto_switcher
