How to Record System Audio in Chrome Without Extra Software

One of the most common problems with screen recordings is audio: the video is fine, but what’s playing on screen — the app sounds, the video call audio, the background music — isn’t in the recording. You got the microphone (your voice, room noise) but not the system audio (what’s coming out of your speakers).

This happens because Chrome separates audio sources. By default, a screen recording captures microphone input. Capturing what the computer is actually playing requires choosing a different source — and knowing where that option appears.

Why system audio isn’t on by default

When you share your screen in Chrome, the source picker shows three options: Your Entire Screen, A Window, and A Chrome Tab. The audio option appears only when you choose A Chrome Tab — and even then, it’s a checkbox you have to explicitly enable.

Sharing “Your Entire Screen” or “A Window” deliberately excludes system audio. This is a browser security decision: broadcasting everything your system plays — notification sounds, background music, audio from other apps — is treated as something that should require an explicit, intentional choice.

Capturing system audio: the Chrome Tab option

If the audio you want to record is playing in a browser tab — a video, a music player, a web app — the Chrome Tab share option captures it cleanly:

1. Start a new screen recording
2. When the source picker appears, choose Chrome Tab
3. Select the tab that’s playing the audio
4. Check the Share tab audio checkbox (it may be unchecked by default)
5. Click Share

The recording captures both the tab’s visual content and its audio output. Other system sounds are not included, which is usually what you want for clean recordings.

Capturing audio from desktop apps

Audio from non-browser applications — a native video player, system alert sounds, audio software — requires different handling. Chrome’s built-in screen capture API does not expose desktop audio in most configurations.

Options:

Use a Chrome extension with desktop audio capture. Extensions that request the desktopCapture permission can, in some configurations, capture system-level audio alongside the screen. The capture dialog will include a toggle for system audio alongside the screen source selection.

Use OS-level audio routing. On Windows, software like VB-Cable creates a virtual audio device that routes system output back in as a recording input. Once active, any screen recorder that accepts a microphone input — including browser-based tools — can capture it. macOS requires similar third-party virtual audio drivers.

Place a microphone near your speakers. Technically the lowest-fidelity option and not recommended for anything that will be shared widely, but sometimes the fastest solution for an occasional capture where audio quality is not critical.

Microphone and system audio together

When you want both your voice and system audio in the same recording:

• In Chrome Tab mode, tab audio is captured automatically once the checkbox is checked. Add a microphone source in your recording settings to mix in your voice alongside it.
• In desktop capture mode via an extension, look for separate microphone and system audio toggles — most screen recording extensions expose both independently.

Always check levels before starting a full session. System audio captured through Chrome Tab mode sometimes comes in lower than expected relative to the microphone. A short test recording with a quick playback check saves time compared to discovering the issue at the end.

What to check if audio isn’t recording

If your recording has no audio or is missing system sound:

• Using “Entire Screen” mode? Chrome doesn’t capture system audio in this mode. Switch to Chrome Tab or use an extension with desktop capture permission.
• Is the Share tab audio checkbox checked? It defaults to unchecked in some Chrome versions — easy to miss.
• Is the correct microphone selected? If you’re getting no audio at all, confirm the right input device is active in the recording settings.
• Is the source tab muted? A muted tab produces no audio output even when tab audio capture is enabled.

Most audio recording problems in Chrome trace back to the source selection made at the start of the session — not something that can be corrected after recording begins.
