Diagnosis
The microphone is likely getting interference, either from electrical noise or a physical obstruction. It's a common gripe with these, especially if you're using the original USB cable.
How to Fix It
Start with the cable. The power supply can introduce a ton of noise. Unplug it and try a different, high-quality USB cable and a different 5V/2A power adapter (like one from a phone). Often, swapping out the cheap or long cable that came in the box fixes it immediately. Also, make sure the microphone hole on the front of the camera isn't blocked by a spider web or dust.
If That Didn't Work
There's a software setting that can sometimes help. In the Wyze app, go to the camera's live view, tap the gear icon, then Audio Settings. Try toggling "Microphone" off and on. If there's an "Audio Mode" option, switch it from the default.
Heads Up
If you're listening through a Google Nest Hub or Alexa Show, the distortion might be from that device's speaker or the audio stream compression, not the camera. Test the audio directly through your phone's speaker first to isolate the problem.
