To share your computer's audio during screen sharing: in Zoom, when you click Share Screen, check the "Share sound" checkbox at the bottom of the sharing dialog (also check "Optimize for video clip" if sharing a video). In Microsoft Teams, click Share and enable "Include computer sound" from the sharing toolbar. In Google Meet, you must share a Chrome tab (not a window or entire screen) and check "Share tab audio" — Meet can only capture audio from Chrome tabs, not from applications. If audio still doesn't come through, make sure the sound is actually playing on your computer (not muted), and that no headphones are intercepting the audio output. Some audio routing setups on Mac require additional software like BlackHole or Loopback to share system audio.
