Hi,
1. Please ensure the Tapo app and the camera's firmware version are up to date.

2. You can refer to the instructions below to troubleshoot if the problem remains.
What should I do if I can't view the Tapo camera?
 

3. You can refer to the below steps to troubleshoot the audio quality issue.
    1) Make sure that there are no obstructions covering the microphone and speaker openings on the camera.
    2) Confirm the microphone and speaker volume of the camera are set at a high level on our app.
    3) Ensure the camera is positioned to allow clear and unobstructed sound reception. Avoid placing it in enclosed spaces or near surfaces that may reflect sound.
    4) Test the audio with your mobile device positioned away from the camera, preferably in a different room. The proximity between the phone and camera during a voice call can cause audio feedback.

Best Regards
