6. Troubleshooting
- No Sound Output:
- Ensure the USB-C connector is fully inserted into your device.
- Verify that your USB-C device supports audio output through its Type-C port. Not all USB-C ports support audio.
- Check if your headphones/speakers are properly connected to the 3.5mm jacks.
- Test with different headphones/speakers to rule out issues with the audio output device.
- Confirm the volume on your source device is turned up and not muted.

- Poor Audio Quality / Static:
- Ensure all connections are secure and free from dust or debris.
- Try connecting the adapter to a different USB-C port or device to check if the issue persists.
- Avoid placing the cable near strong electromagnetic interference sources.
7. Care and Maintenance
