Troubleshooting no-audio

I have the same web page open in 2 Chrome browsers on the same laptop (MacOS).

The web page produces audio only (OPUS) to the mediasoup-demo server and plays audio from received from the server from the other WebRTC client. I expect to speak / hear between the two browsers… and when running on the same machine, lots of echo. However, there is no sound.

I am trying to determine where the issue lies. When I look at the mediasoup server stats, everything looks correct to me. Do you see anything fishy? Is there something else I should look for on the server?
