Your Webcam
For Chrome/Edge: When sharing your screen, select "Chrome Tab" (not Window/Screen) and CHECK "Share tab audio"
For Mac users: System audio capture is limited. Consider using OBS Studio or QuickTime for full audio.
Alternative: Use headphones to prevent echo, and your mic will pick up the YouTube audio from your speakers.
Tab Selection Issues? If tabs don't appear, try: 1) Refresh the page, 2) Switch to Window tab then back to Tab, 3) Use a different browser
