Using zoom on macbook air
I bought a new 2020 MacBook Air in April. I use Zoom for teaching fitness classes. When using my MacBook Pro I have no issues at all but when using my Air it sounds like the fans are going (don't get this sound with the Pro) and also the mic volume increases and increases until I turn off the mic on zoom and turn it back on again! It's really strange! The laptop is propped up so that air can filter underneath. My Pro is really old so purchased the Air to teach from and I'm completely unable to use it for teaching. Help!
