Hi @DonC, have you tried the two-way talk feature using the regular Ring app? If not that might be a good first step, if that does not change the audio I would suggest calling support as they would be happy to look further at what variable could be causing this audio concern.
I installed a brand new doorbell II pro today and I am having the same audio garbled issue. I was just testing it with my husband at the door. his voice was broken, I could barely hear a full sentence and it was the same for him outside. We are using iPhone 8 with Ring app. I will call support tomorrow but I want to know if the support was able to resolve this issue reported by DonC. Can you please share what you had to do to resolve it? Thank you
