Hi,
1. Currently, the latest firmware of the Tapo C220 V2 is 1.1.1 Build 250818 Rel.69983n, so your camera has the latest version.

2. You can click here to find the contact info of our technical support.
 

3. For the reported sound detection phenomenon, please provide the following information for further analysis.
    1) On the camera's Device Settings > Detection page, are the Sound Detection types (Baby Crying, Glass Break, Dog Barks, and Cat Meows) enabled? If so, what are the sensitivity values for each detection type?

    2) Please go to the camera's Live View page to record a video manually, showing that there are Baby Crying, Glass Break, Dog Barks, or Cat Meows occur, but the camera won't make an alarm sound, send a notification, or record detection video clips. Then, download the video to your phone and send it to us.
You can upload the video to your cloud server (such as Google Drive), generate a download link, and send it to me (@Solla-topee) via a private message.

  3) Btw, please ensure your Alarm or Notification feature is configured correctly. For example, on the Notification settings page, please ensure the sound detection types are selected in the Activity Type page.

Best Regards
