Utilizes a systemd service to setup the headset when it is plugged in.
- Set the stereo sink as the default sink
- Redirect audio of all currently running applications to the new sink (usefull for apps like Spotify which would otherwise require a restart)
- Set the volume of the ALSA sound cards to maximum for both mono and stereo output. This way volume is in complete control of PulseAudio.
Manually install the service and copy the steelseries-arctis-pro-wireless script to /usr/local/bin or install as an Arch package using makepkg -i.
Then enable the systemd service via sudo systemctl enable steelseries-arctis-pro-wireless.service.
