Is there a place to stop the game from accessing my mic when its launched?
What operating system are you using? We don’t access the camera, just the microphone for VOIP which is not going to listen by default.
Windows 10. The camera has a built in mic so that is probably why the LED is lit up.
Are you using a test build from ioquake3.org?
I downloaded the test build directly from the link on the site.
