Sorry to hear about the sound issues. If you're having trouble recording on a laptop or desktop, you might try recording on a smartphone.
The Tribute creator is able to increase the volume on any video in their Tribute. If you believe the audio will still be too low even after the volume is adjusted then please record your video again and make sure the audio is being captured at a reasonable level.
If you're still unsuccessful, please share the video with us through here. It's really simple, click to find out more.
Make sure your computer or smartphone's microphone is on when you are recording.
