Why don't I hear any sound or only hear static noise when watching the live feed in Mi Home security camera 360 ° 1080P?

Solution：

Sound is muted by default when watching the live feed. Please use the volume bar in the bottom left corner of the live feed window to adjust the volume. If the volume is still too low, try turning up your phone's volume.

If there is static noise or interference when watching the live feed, move your phone away from the camera, and avoid placing the camera near electronic devices like fridges or Microwave ovens.
