Doorbell hiss

I am having a terrible time with the audio on the doorbell. The video is fine but the audio during live view and events has a terrible hissing and popping garbled sound. So much so that it makes any speech during a live event inaudible. It drowns it out. The interesting thing is just after a power cycle at the breaker, the audio is fine for maybe 2-3 minutes, Then it goes back to the garbled hissing. 18.8v at the transformer, 18.2v at the doorbell, No wifi issues. Changed the router channel. The audio on all my other Wyze cams is fine (outdoor and pan indoor).

Anyone else having these issues with the audio? Or have any ideas?
