I just installed the Ring Video Doorbell 2 weeks ago and also have this white noise mentioned in blogs. Tried all the trouble shooting tips and still have the white noise. This is definetely either hardware or software for sure. It’s a joke to put one through all this for a $200 product. Since I purchased the unit during the Christmas holidays it is beyond the return date or else I would return for a refund. This is definetely on Ring for sure. hopefully a firmware update or something is in the works.
