Why Browser Tab Audio Is Not Working
If browser tab audio is missing, the problem is usually not the recorder itself. It is usually the browser share dialog, the chosen capture mode, or the browser/OS combination.

Do this next
Start a new recording and choose a browser tab rather than full screen or a generic window.
Enable the audio checkbox in the browser share dialog if it appears.
Record a short test clip to confirm the tab audio is actually present before continuing.
Common questions
Why does tab audio fail even though mic recording works?
Because tab audio and microphone audio are different capture paths. The browser share dialog can allow one and not the other depending on what you selected.
Do I need to choose a browser tab specifically for tab audio?
Usually yes. Chromium tab capture is the strongest path for tab audio; full-screen or window capture often behaves differently.
Can the recorder force the browser to expose tab audio?
No. The browser controls which capture options appear in the share dialog.
The browser dialog matters most
Browser tab audio is controlled first by the browser’s own share dialog. If the browser does not expose the audio option for the selected tab, the recorder cannot invent it.
Use tab capture, not a generic guess
If your goal is tab audio, choose a browser tab explicitly in the share picker. That is usually more reliable than choosing an entire screen or a different capture surface and hoping the audio follows.
Test before the real take
Because tab-audio support depends on the browser flow, a short test recording is the fastest way to verify the setup before you do the real demo, lesson, or walkthrough.
