Steelseries Arctis Pro Wireless on Stereo very quiet

Solution 1:

Gaming headsets like the Arctis Pro Wireless support multiple audio channels, one for voice chat in mono, and the stereo output. The volume for the stereo channel is not controlled when using the Settings/Sound volume setting. But you can use command line alsamixer tool increase the volume for the stereo channel. Open a terminal, launch alsamixer. Press F6 to select the sound card Arctis Pro Wiresless. You should see the following screen:

Select the PCM 1 channel which controls the stereo volume and raise it to a higher value like 90% (use arrow keys left/right to select, up down to increase decrease volume). You can leave alsamixer pressing the ESC key. This should fix the problem, but you need to save the setting so it's reapplied after a reboot. This can be achieved by running:

> sudo alsactl store
