Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsTo use NVIDIA Broadcast in Streamlabs Desktop, select Microphone (NVIDIA Broadcast) as your audio input for microphone effects, or add Camera (NVIDIA Broadcast) as a video capture source for camera effects. Configure the input and effect in NVIDIA Broadcast first. For the camera, set the same resolution in Broadcast and Streamlabs. Check NVIDIA’s current system requirements before installing because GPU and driver support can change.
Choose what you want NVIDIA Broadcast to process
NVIDIA Broadcast creates virtual Windows devices that compatible applications can select. You can route your microphone, camera, or both through Broadcast; using one does not require changing the other. Streamlabs must use the Broadcast virtual device for the input you want processed.
- Microphone only: Select the Broadcast virtual microphone in Streamlabs to use microphone effects.
- Camera only: Add the Broadcast virtual camera as a capture source in the scene where you want it.
- Both: Set up each route separately. Choosing the microphone in global audio settings does not add a camera to a scene.
Broadcast is not a general-purpose effect for every PC. Check NVIDIA’s current Broadcast FAQ and setup information for the supported operating system, GPU, driver, and feature requirements before installing or buying hardware.
Install and configure NVIDIA Broadcast
- Check compatibility. NVIDIA’s setup guide reviewed for this article lists Windows 10 64-bit, at least 8 GB of RAM, internet access during installation, and a GeForce RTX 2060, Quadro RTX 3000, TITAN RTX, or higher GPU. NVIDIA’s regional setup guide also lists driver 570 or above. These requirements are version-sensitive; verify the current requirements on NVIDIA’s Broadcast App Setup Guide before proceeding.
- Install and open Broadcast. In the app, choose the physical microphone or camera you want it to process.
- Turn on the effect you want. Configure the desired microphone or camera effect in Broadcast. The app is where you choose the source device and its processing.
- Set camera resolution if using the virtual camera. Configure the camera resolution in Broadcast, then use the same resolution for its Streamlabs capture source.
Route microphone audio to Streamlabs
You can select the virtual microphone in Streamlabs’ audio settings, or add it as an audio capture source. Use the route that fits your existing setup, and avoid adding the same processed microphone through both routes: doing so can make the signal sound doubled.

Set it as the global microphone
- In Streamlabs Desktop, open Settings > Audio.
- Under Mic/Auxiliary Device 1, select Microphone (NVIDIA Broadcast).
- Check that the Streamlabs audio meter responds when you speak. If it does not, confirm that Broadcast is using the intended physical microphone and that the virtual microphone is selected in Streamlabs.
Add it as an audio input source
- In the scene’s Sources list, add an Audio Input Capture source.
- Select Microphone (NVIDIA Broadcast) as its device.
- Check the audio meter and listen to a test recording or preview. If the mic is already routed through the global microphone setting, remove or disable one route to prevent duplicate capture.
NVIDIA documents the global audio route as selecting Microphone (NVIDIA Broadcast) under Settings > Audio > Mic/Auxiliary Device 1 in its setup guide. Streamlabs also documents the audio-input-source route in its Broadcast integration guide.
Add the NVIDIA Broadcast camera to a scene
- Open the scene where the camera should appear.
- Add a Video Capture Source or Video Capture Device, depending on the label shown in your Streamlabs Desktop version.
- Choose Camera (NVIDIA Broadcast) as the device.
- Leave the source settings at their defaults initially, as NVIDIA’s setup guidance recommends. If you change the camera resolution, set it in Broadcast and match it in Streamlabs.
- Check that the camera image appears in the scene preview.
Streamlabs specifically notes that the resolution in Streamlabs must match the resolution in Broadcast or the camera may not display correctly. Its integration guide covers the source setup.

Check permissions and confirm the signal
If Streamlabs cannot see or use a camera or microphone, check that the app has the relevant camera and microphone permissions. Streamlabs’ getting-started guide, dated July 22, 2026, includes these permission checks. Then confirm that Broadcast is open, the intended physical input is selected there, and Streamlabs is pointed to the correct NVIDIA Broadcast virtual device.
Troubleshoot common setup problems
| What you see | What to check |
|---|---|
| Microphone effects are not reaching Streamlabs | Make sure Streamlabs is set to Microphone (NVIDIA Broadcast), not just the physical microphone. In Broadcast, verify the selected physical source and that the intended effect is enabled. |
| The camera does not appear in the scene | Confirm that you added a video capture source and selected Camera (NVIDIA Broadcast). Check camera permissions and match the source resolution to Broadcast. |
| The microphone or camera device is missing | Check app permissions, confirm that Broadcast is installed and configured, and select its virtual device in the appropriate Streamlabs audio setting or scene source. If it remains unavailable, consult current NVIDIA or Streamlabs support; the documented setup guidance does not establish one universal fix for every missing-device issue. |
| Audio sounds doubled | Check whether the same Broadcast microphone is active both as the global microphone and as an Audio Input Capture source. Keep only the route you intend to use. |
| Broadcast will not install or a feature is unavailable | Recheck NVIDIA’s current operating-system, GPU, driver, and feature requirements. The listed minimum GPU and driver can change, so do not treat an older setup guide as a guarantee of compatibility. |
Or let it run in the cloud
NVIDIA Broadcast processes a microphone or camera input for Streamlabs on your PC. StreamNeo is a separate option for a different job: keeping an uploaded video live on YouTube 24/7. It does not replace Broadcast or stream a live camera. Upload a recording or build a playlist, add your YouTube stream key once, and go live; StreamNeo loops it in the cloud, so nothing has to stay on at home. It streams the uploaded file as made, up to 4K 60fps, at one price per slot, with automatic recovery if YouTube drops the stream. The first day is free with no card. Monthly billing is $9.99 per month. Learn more at StreamNeo, or start your free day.
