GOOD TO KNOW
Microphones can capture people, media, and private conversations elsewhere in the room. Mute or leave when you do not intend to transmit audio.
Check permission and the selected input
Allow microphone access in the browser site controls, select the correct input device, and make sure the operating system has not muted or blocked the browser.
Reduce echo and background noise
Use headphones, lower speaker volume, move away from fans, and place the microphone closer to your voice. Close recording or meeting apps that may hold the same input.

QUICK ANSWERS
What people usually ask.
Can I use video without a microphone?
The native video mode requests both devices because a live video conversation normally includes sound. Choose text if you do not want microphone access.
Why is the wrong microphone active?
The browser or operating system may remember a previous default. Select the intended device in the browser or system sound settings, then reload.
