How to troubleshoot and resolve a headset no sound/uneven audio balance Manual

A Razer headset with no sound, poor audio, or uneven balance might be caused by dirt or debris in audio ports and on the audio jack, improperly plugged-in audio jack, hub connections, incorrect playback device levels or settings, software issues, or faulty audio drivers.

Below are the steps on how to troubleshoot a headset with no sound, poor audio, or uneven balance:

Wireless Headsets

Check the volume level and connection of your headphones and audio source. If your headphones connect via Bluetooth, ensure that the headphones and your audio source are paired and connected properly. If you are using a computer, make sure your headset is selected as the playback device in your audio settings.

3.5 mm Headsets

1. Check the audio ports and audio jack for any dirt or debris that may cause the issue.
2. Check if the audio jack is plugged in properly.
3. For headsets with a splitter cable, ensure the connection between the splitter cable and the headset’s audio jack is secure and not loose.
4. For headsets with in-line volume or headset volume controls, ensure it is not set too low.
5. Ensure the system volume is not set too low or muted.
6. Ensure the device is set as the default playback device.
   1. Right-click on the speaker icon on the system tray and select “Open Sound settings”.
   2. Under “Related Settings”, click “Sound Control Panel”.
   3. Right-click on the system’s onboard audio playback device, for example, Realtek High Definition Audio, and select “Set as Default Device”. It is the default device if it has a green checkmark on it.
