My Ring 2 has very low output on the doorbell speaker. I have tried several Android devices and tried using Amazon Alexa. The person speaking cannot be heard unless you are about 1.5-2FT away. Very disappointed by the peformance.
That setting is probably specific to the device you are using to answer the door. I tried it and it does not fix the volume issue.
I also use Alexa to answer to door. You can hear quit well from the Alexa but the person at the door cannot hear you.
I have had both Ring and Ring 2 behave exactly the same.
This is a Ring firmware issue. The bell sound is plenty loud, just not the voice output.
spent a few hours on phone with support a few months ago, still same issue. Was never corrected on that call and I have just basiclly given up trying to talk to people. This is a real issue and doesnt make sense since the doorbell chime itself is nice and loud. No reason the voice shouldn't be as well.
