6.2 Microphone Not Working or Unclear
- Check Mute Switch: Ensure the in-line microphone mute switch is in the "unmute" position.
- Device Settings: Verify microphone input settings on your connected device (e.g., PC sound settings, console audio settings). Ensure the TX20 is selected as the input device.
- Application Settings: Some applications (e.g., gaming chat, video conferencing) have their own microphone settings. Check these as well.
- Test on Another Device: As with audio, test the microphone on another device to isolate the problem.
6.3 Static or Distorted Audio
