No Audio?

Unfortunately the sound is missing. 
Would it be possible to add it?

The camera has normal sound and has also worked with sound in Protect before.

Nevertheless, thanks to your project
Since the new update of Unifi, 3 Onvif Cams are now working

Unfortunately only 2 worked because one of them has 2K. Thanks to your project I can finally integrate 3 cameras by switching the 2k to FullHD
