How to Share Your Screen and Computer Audio in a Browser Live Stream
To share your screen and computer audio in a LiveSnap.tv browser live stream, start a desktop broadcast with your camera active, open the screen-share picker, choose a tab, window, or entire display, and enable audio if your browser offers it. Screen sharing is available in the desktop studio only, and computer audio depends on browser and operating-system support.
Start with the camera before you switch to screen sharing
On LiveSnap.tv, screen sharing is a desktop-studio feature. Before you can share your screen, you need to occupy the stage with an active camera stream.
Once your camera is live, start screen sharing from the desktop studio. LiveSnap uses the browser’s screen-capture picker, so the exact labels and options you see may vary by browser and device.
- Open the desktop studio in your browser.
- Make sure your camera stream is active first.
- Start screen sharing from the studio controls.
- Choose the source your browser offers: a tab, application window, or entire display.
Choose the right source and enable audio when the browser offers it
When the browser opens the share dialog, select the tab, app window, or screen you want to show. If your goal is to include computer sound, look for the browser’s audio option in that same dialog.
Computer audio is optional. LiveSnap can mix it with your microphone audio when the browser returns an audio track and you enable it. Chrome and Edge may show an additional Share audio option, but that depends on the selected source, browser, and operating system.
If you do not see an audio option, that does not necessarily mean something is broken. It usually means the current browser, operating system, or chosen source does not support audio capture for that share.
- Pick the content source you want viewers to see.
- Enable Share audio or the equivalent option if it appears.
- Remember that computer audio support is browser-dependent.
- Expect microphone and shared-system sound to be mixed only when an audio track is available.
What happens after you start sharing
LiveSnap replaces the outgoing video track without restarting the whole WebRTC publication. In practice, that means the broadcast switches from camera to screen while the stream stays live.
If computer audio is enabled, it has a separate volume control. That lets you balance shared sound and microphone input instead of treating them as one combined source.
If you stop screen sharing, LiveSnap returns the broadcast to the camera. If the computer-audio track ends first, the screen video can continue on its own.
- Screen share replaces the outgoing video track.
- Computer audio and microphone audio are mixed only when audio capture is available and enabled.
- Computer audio can be adjusted separately from the microphone.
- Stopping screen share returns you to the camera feed.
How to switch back to the camera
To return to the camera, stop screen sharing from the browser or the LiveSnap studio controls. The broadcast switches back to your camera view.
This transition does not require you to restart the entire broadcast. If you plan to move between slides, demos, and face-to-camera segments, you can use the screen-share control as a toggle between sources.
- Stop screen sharing in the browser or studio.
- The broadcast returns to the camera.
- You do not need to restart the full publication when switching sources.
Troubleshooting missing computer audio, permission prompts, and duplicated sound
If computer audio is missing, first check whether your browser actually offered an audio option in the share dialog. Some combinations of browser, operating system, and source do not provide an audio track at all.
If the permission prompt was cancelled, open screen sharing again and approve the browser dialog. The browser must be allowed to capture the selected screen, window, or tab, and camera and microphone access also require explicit browser permission.
If viewers hear echo or duplicated sound, use headphones. Speakers can send the shared audio back into the microphone, which may cause the audience to hear the same sound twice.
If the browser or device combination does not support the source you want, try another supported setup or choose a different share source. For example, a tab may offer audio where an entire display does not, or the reverse may happen depending on the browser and operating system.
Before opening the browser picker, open the Audio Mixer and enable Computer audio. LiveSnap uses this setting to request an audio track together with the screen. If you enable it only after sharing has begun and no audio track was captured, stop sharing and start it again, then select Share audio in the browser dialog. The separate Computer audio level control adjusts the shared sound without changing the microphone level.
- No audio option shown: the browser, operating system, or source may not support it.
- Cancelled prompt: reopen screen sharing and allow the browser request.
- Echo or doubled sound: use headphones instead of speakers.
- Unsupported combination: try a different browser, operating system, or source.
What quality to expect
LiveSnap requests up to 1920x1080 at 30 fps, but the actual result depends on the account profile, browser, selected source, and network connection. Do not assume a fixed resolution, latency, or audio quality.
That limitation matters for screen sharing as much as for camera video. If your source, browser, or connection changes, the shared output can change too.
- Requested settings are not guaranteed.
- Actual quality depends on account profile, browser, source, and connection.
- Audio support and video quality can vary from one sharing session to another.
Frequently asked questions
Can I share my screen from the mobile studio?
No. Screen sharing is intentionally limited to the desktop studio in LiveSnap.tv.
Does computer audio work in every browser?
No. Computer audio depends on whether the browser returns an audio track and on browser, operating-system, and source support.
What should I do if I only want viewers to hear the shared tab?
Use the browser’s share dialog and enable audio only if your browser offers it for that tab. Availability depends on the selected source, browser, and operating system.
What happens when I stop sharing?
LiveSnap switches the broadcast back to your camera without restarting the whole publication.
