Hello Cmeans,
I'm here to assist you with your Nest doorbell audio issue. We'll work together to identify the cause of the problem and find a solution. Just to check, what type of Nest doorbell are you using? Was it working after the installation? Have you enabled talk and listen on the app? Here is a link to talk and listen with Nest camera or doorbell.
I look forward to your response.
Best,
Edmond
