Why Your Screen Recording Has No Audio
If a browser-based screen recording has no audio, the cause is usually one of four things: the wrong capture mode, no mic permission, the wrong input device, or unrealistic expectations about system-audio support.

Check whether you were trying to capture microphone audio, tab audio, or both.
Verify browser permissions and confirm the correct microphone is selected.
Record a short test clip again and play it back locally before doing the full recording.
Common questions
Why does my screen recording have video but no audio?
In browser recording, that usually means the wrong audio source was selected, the browser lacked mic permission, or the chosen capture mode did not support the audio you expected.
Can browser recording capture both mic and system audio?
Sometimes, but not always. Browser and OS support varies, and tab-audio capture is usually more reliable than general full-system audio capture.
What is the fastest way to test whether audio is working?
Make a very short test recording after checking permissions and input selection, then play it back locally before recording the real clip.
Start with the audio type
The first question is whether you expected microphone audio, tab audio, or system audio. Those are not the same thing in browser recording, and the fix depends on which one is missing.
Check browser permissions and device selection
If microphone narration is missing, confirm the browser has mic permission and that the correct input device is selected. Browser recorders can only capture the devices the browser is allowed to access.
Be honest about system-audio limits
If the missing audio was supposed to come from a browser tab or from system playback, the limitation may be the browser share flow rather than the recorder UI. Chromium tab capture is usually the strongest path here.
