Starting the test will check for your microphone installation. if you are seeing a tick mark against microphone (as shown in above image) you have microphone installed. but our classroom is not able to acquire the microphone for communication. so you have to give permission for the browser to use microphone
To give permission,
Go to the browser settings -> privacy and security -> site settings -> *.classroom.email and give permission to microphone and camera.
In chrome, you will get a similar screen like below. Change the value to Allow

You will have to do it for all subdomains of classroom.email. This will solve the above problem with microphone
