SteelSeries Arctis 5 for Linux
The SteelSeries Arctis 5 is a gaming headset, which has two stereo audio outputs. One for voice chat and one for the rest of the sound. It can be mixed between with a physical knob.
By default, pulseaudio only enables the voice chat output (testing on Ubuntu Bionic). This profile enables the second (game) output and the udev rule makes sure this profile is used when plugging in the device.
Ubuntu / Linux Mint
See instructions on http://www.arakhne.org/unbuntu.html and install the package
Install from by copying the following files:
The following files are already well-configured on Ubuntu Bionic:
pulseaudio -k pulseaudio --start
After that, plug in the device to see if it works.
