Tapo C110 audio issues - rythmical ringing noise
Hello community,
I finally received my Tapo C110, looking very much forward to the improved picture quality due to the 3MP resolution.
As expected, the picture is great, but there is something wrong with the audio. For all my four C110 cameras there is a loud rhythmical ringing noise in the audio, when using the app on Android or ios, which is very annoying. It is also audible in the recordings on the SD card (Samsung Evo 256GB).
As it occurs for all four cameras, I assume there is either a hardware issue or (I hope) an issue with the firmware.
I tested in different rooms, in parallel with a C100 - everything points to the camera itself as origin of the issue.
I would be very happy to receive some feedback, if someone also encounters this and if there is a solution available
Otherwise I need to return all cameras and will sadly stick with the C100.
Thanks!
regards, Olaf
Update:
The noise seems to be a problem caused by playback on the phone (codec problem?) - on the phone I do hear the ringing noise, but if I play the same file on my PC using VLC, there is NO noise. I used e.g. iPhone 12 with iOS 14.7.1 and latest app version from appstore (Germany). Noise changed depending on resolution used for recording: 720p - no ringing, just crackling/buzzing noise, 1080p ringing noise, 3MP high-pitched ringing noise.
Update 2:
I also tried with the new C210 - no issue here. The noise is only observed for the C110. Also tested with iOS 14.8 and iOS 15, no difference.
