I have the same problem with my Ring Video Pro doorbell. The video is fine, but the audio is choppy and static noises. I have tried all the steps you tried and no luck. I have also tested my wifi upload and download speeds near the doorbell and they are good. In device health, my transformer voltage is “Good”. My RSSI is 38. And the device status reads “All systems Operational”. Do you have a solution to this problem yet? If yes, would you share your solution with me?
