6. Troubleshooting

6.1 Common Issues and Solutions

• Issue: Volume adjustment is slow or unresponsive when turning the knob quickly.
  Solution: The controller is designed for precise, gradual volume adjustments. Turning the knob too rapidly may result in missed inputs. Adjust the volume at a moderate pace for optimal response.
• Issue: Next/Previous track buttons do not work in web browsers or specific applications.
  Solution: The functionality of next/previous track buttons can vary depending on the application or web player. These controls are primarily designed for system-level media players. Volume and play/pause functions should generally work across most applications.
• Issue: Device is not recognized or functional on Linux, Remote Control Desktop, or VMWare.
  Solution: The YMOO S04 is not designed to be compatible with these specific operating environments. Ensure you are using a supported operating system (Windows 7/8/10/11 or Mac OS).
• Issue: The blue LED light around the knob cannot be turned off.
  Solution: The blue LED is an integrated design feature and cannot be manually turned off or adjusted.
• Issue: No sound output.
  Solution: Ensure the USB cable is securely connected to both the controller and your computer. Check that your speakers or headphones are correctly plugged into the controller's 3.5mm output port. Verify that the system volume is not muted or set to zero.
