Click on “Local settings” in the main menu and then on the “Audio” tab. In the output device and microphone selection, you can select other audio devices and microphones in the drop-down menu. If your headset is not listed there, close the application, reconnect the headset to your computer and start the application again.
If you continue to have problems with audio or microphone transmission, switch to your computer’s audio or microphone in the same drop-down menu. Remember to mute yourself in this case due to possible noise interference.
