Software tutorial recording has no sound? Fix it

You finish recording a software walkthrough, but the exported clip is silent. Or the screen is clear while your voice, the program audio, or both are missing. Before recording the whole tutorial again, make a short test that shows which sound source is not being captured.

The Screen Recorder can record a screen, window, or browser tab with sound, a microphone, and a camera. It runs in a desktop browser, not on phones. Use it to check the actual saved clip, not just whether you can hear yourself while recording.

Test the recording before you redo the tutorial

Open the Screen Recorder on your computer. Decide what you need to capture: a browser tab, one app window, or the full screen.
Choose the source that contains the tutorial. If the demo is in a browser, try sharing that tab when you need its audio. If it is a desktop program, choose its window or the full screen. The audio choices available can depend on your browser and operating system.
Before recording, turn on the available sound option for the selected source. Turn on the microphone option as well if you are narrating. Allow microphone access if the browser asks.
Record about 10 seconds. Speak a sentence, make a sound in the software you are demonstrating, and stop the recording.
Play the saved clip from the beginning. Check separately whether your voice and the software or tab audio can be heard.

Use the same capture source and audio choices for the full tutorial only after this short test succeeds. A microphone you can hear through headphones is not necessarily being recorded, and a screen capture does not always include every sound playing on the computer.

What the result means

Your voice is clear, but the software audio is missing

The microphone is being captured, but the selected screen source is not providing the program audio. If the demo is in a browser, try selecting its tab and enabling tab audio in the browser's sharing picker. For desktop software, the browser or operating system may not offer audio capture for that particular window or screen. Check the available source options before assuming the recording is broken.

The software audio is clear, but your voice is missing

The capture source is working, but the microphone was not included, the wrong input was selected, or permission was blocked. Check that the microphone option is enabled in Screen Recorder and that the correct microphone is selected in your computer's input settings.

The clip has no sound at all

Check that at least one audio source was enabled before you started sharing. Then check the browser's microphone permission and your system's input and output settings. If you are recording sound from a browser tab, remember that tab audio and microphone audio are separate sources.

You hear sound while recording, but the clip is silent

Monitoring audio live does not prove it was saved in the recording. Play the resulting clip in another media player, and confirm that you are opening the newest test file. If the new file is still silent, repeat the test with a different capture source and check its audio options before making a long recording.

How to fix it

Check the capture source and sound options. Start a fresh test and select the tab, window, or screen that actually produces the sound. Enable the sound option for that source before sharing. A tab capture may include audio from that tab, while a window or full-screen capture may have different choices.
Choose the microphone you intend to use. Unplug any headset you are not using, or select the headset or built-in microphone in the system settings. Speak at a normal distance and make another short recording. If you need to isolate the mic first, use the Microphone Test to check its input level and record a short sample.
Allow the browser to use the microphone. Open the site permissions from the icon beside the browser address bar and set Microphone to Allow. Reload the page, then grant permission if asked again. You do not need to enable a microphone if you only want to capture software audio.
Check operating-system microphone access. On Windows 11, open Settings › Privacy & security › Microphone. Turn on Microphone access and allow desktop apps to access the microphone. On macOS, open System Settings › Privacy & Security › Microphone and allow your browser.
Check system sound settings. On Windows 11, open Settings › System › Sound and confirm the correct device appears under Input and Output. On macOS, open System Settings › Sound and check both Input and Output. This helps catch a muted or incorrectly selected device, but it does not make every browser capture system audio.
Allow screen recording access on a Mac. If macOS blocks the browser from capturing a window or screen, open System Settings › Privacy & Security › Screen & System Audio Recording and allow the browser if it is listed. The setting name can differ by macOS version. Quit and reopen the browser after changing access, then make another short test.
Close other apps that may be using the microphone. Quit meeting, recording, and voice-chat apps, then test again. If the result changes, one of those apps may have been using or changing the microphone input.

Why tab, window, and screen audio can differ

Screen recording combines separate things: the picture being shared, audio from the selected source, and audio from your microphone. A browser may offer tab audio when you share a tab but not offer the same choice for a desktop window. The operating system and browser decide which capture options are available, so a missing option may be a platform limit rather than a fault with your microphone.

Also check the sound that matters for the lesson. If the tutorial software is silent during the test, the recording cannot capture its audio. If you need to explain clicks and menu choices, a microphone narration can still work even when the software itself makes no sound.

Screen Recorder runs in your browser, and the recording stays on your device. Don’t include private messages, passwords, or account details in a tutorial capture.
