Hi,
What volume is too low? For example, when someone is talking to the camera, do you hear low volume in the Tapo app > camera's live view page, or is the volume low on the camera end when you talk via the Tapo app?

Please refer to the following instructions to check whether your camera's hardware, configuration, and placement environment are proper: Troubleshooting for better audio quality of my Tapo camera 

Best Regards
