Screen sharing during FaceTime call turned off my mic

Hi kyouell,

welcome to this Apple (user-to-user) Community!

Re: "Screen sharing during FaceTime call turned off my mic I initiated screen sharing when on a FaceTime video call on my MacBook Air (Sequoia 15.6.1) and I was automatically muted. The mute button didn't look "on" so I clicked it twice to turn it on and then back off again. This had no effect."

"How can I stop this from happening so I can share my screen and speak about what I'm sharing?:

Am no expert in this area, yet your question to the community deserves some response, if only to keep your post active, and provide more opportunity for experienced FaceTime users to share their knowledge with you.

Some things we may screen-share (eg: videos, apps we use for shareplay, etc.) may have audio of their own that needs the use of the mic. Sorry I don't know how much control we have over the mic during screen-sharing in FaceTime. (Am currently using other software and app for calls on my Mac)

Apple Support's articles may ormay not be helpful:

If needed: Choose a camera or microphone for FaceTime calls on Mac - Apple Support

However: Manage Screen Sharing and Screen Control in FaceTime - Apple Support

does not mention control of the mic.

Else: restarting your Mac (Apple menu > Restart) often restores order if something is not working as expected.

Wondering whether you checked whether the audio level during screen-share was loud enough for the task.

From the Apple Menu (In top menu bar) > System Settings > Sound > check sliders for volume, and balance.

For MacOS Sequoia:Change audio options for FaceTime calls on Mac - Apple Support has audio options.
