VR-1HD: Audio Troubleshooting Guide
-Make sure REVERB button is off (one of the Audio Effects buttons)
-Press Level Setup and Mute any HDMI sources that have built-in mics (GoPro's have mics you can't disable in camera, so use page 4 of that menu to mute it)
-Check computer speaker output is not set to VR-1HD, otherwise it will send audio back to the switcher via "USB FROM PC"
If the audio is not embedded, Audio Follows Video may be turned on, or the Audio Mute may be enabled:
