8. I can only switch between speaker and headset. It says 2.0 HD and all other buttons do not work
You most likely have set your main audio device to 24Bit. All other functions do only work on 16Bit.
To reverse this:
Go to Playback Devices.
Double-click the GSX 1000/1200 Pro main audio.
Go to the Advanced Tab and then set to 16Bit 44100 Hz and press apply.
9. I hear buzzing noises with the GSX 1000/ 1200 Pro and my headset
This is a very intensely debated topic among the sound engineers and software developers and
everyone who is involved in the world of sound. There is however one main rule to follow, which most
of the time prevents buzzing: The main cause for buzzing is over-amplification on output devices.
Therefore, turn up and max the volume in the application first (Games, Skype or anything else that
will produce sound) before amplifying (volume through your output device (here your GSX). In your
setup, you amplify your output device via the GSX.
10. Why are there two playback devices listed as “GSX 1000 Communication Audio” and “GSX 1000
Main Audio”?
The Main Audio device has the Surround Sound processing, and should be set as your default
playback device. The Communication Audio is a separate audio channel and should be your default
communication channel. Having both, Main Communication and Main Audio in the same channel
would result in surround processed voices which deteriorates communication quality.

the GSX 1200 Pro interesting for a professional studio/ esport team setup, rather than for the casual

communication software such as Skype, Discord, and Teamspeak.
