Wyze Cam v2 constant buzzing/crackling sound from cam-speaker

I bought it for about a month ago. It has latest firmware and is also flashed with RTSP.

It started with constant buzzing/crackling sound from the built in speaker that wont go away no mather what I do. And now it’s not connecting to wifi and shows as offline in the app.

I’ve tried reset to factory settings, but it won’t respond
I’ve tried reflashing firmware, but it seem to not responding to the button at all.
It seems like it is dead with speakers buzzing…

I’ve tried the support, but saadly it’s probably the worst support-system I’ve tried. It’s not even close to my problem when trying to find solution. Resulting in not getting to the warranty-part of it…
