Install NVIDIA Broadcast on a compatible Windows PC, enable the microphone or camera effect you want in Broadcast, then select its virtual device in Streamlabs Desktop. For audio, use Microphone (NVIDIA Broadcast) under Settings > Audio; for video, add a video-capture source to your scene and select Camera (NVIDIA Broadcast). Camera resolution must match in both apps.
Before you install: check compatibility
NVIDIA Broadcast is not supported on every PC. NVIDIA’s setup guide 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 guide lists driver 570 or above. These are version-sensitive requirements, so check NVIDIA’s current Broadcast App Setup Guide and regional setup guide before installing or buying hardware.

Broadcast creates virtual Windows audio and camera devices. Supported applications can select those devices like other inputs; Broadcast applies the selected effects to the physical source you configure in its app. NVIDIA describes the app and supported features in its Broadcast FAQ.
Install Broadcast and choose the effect
- Install NVIDIA Broadcast using NVIDIA’s current setup instructions. Internet access is listed as an installation requirement.
- Open Broadcast and select the physical microphone or camera you want it to process.
- Turn on the effect you want for that input. Configure the source and effects in Broadcast; Streamlabs will receive the resulting virtual device.
- Decide which route you need: microphone only, camera only, or both. You do not have to change every input if you only want one effect.
Route the processed microphone to Streamlabs
Use the global audio setting if you want Broadcast to be the microphone input throughout Streamlabs:
#1 Best Overall
- AI Performance: 767 AI TOPS
- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
- In Streamlabs Desktop, open Settings > Audio.
- Under Mic/Auxiliary Device 1, choose Microphone (NVIDIA Broadcast).
- Check that the selected input is the Broadcast virtual microphone, not just the physical microphone. Avoid adding the same processed microphone a second time as an audio source, which can result in duplicated audio.
NVIDIA documents this Streamlabs route in its setup guide. Streamlabs also describes selecting the Broadcast device through an Audio Input Capture source in its Broadcast integration guide. Use the route that fits your current Streamlabs setup; do not select the same microphone both globally and again as a separate source unless you intend to use both.
Add the Broadcast camera to a scene
- Open the scene where you want the camera to appear.
- Add a Video Capture Source or Video Capture Device (the label can vary by Streamlabs version).
- Select Camera (NVIDIA Broadcast) as the device.
- Set the camera resolution in NVIDIA Broadcast, then set the same resolution for the Streamlabs camera source. Streamlabs notes that a mismatch can prevent the camera from displaying correctly.
- If you are unsure about the source settings, NVIDIA’s guide advises leaving them at their defaults and changing the camera resolution in Broadcast.
Adding the virtual camera is separate from choosing a microphone in global audio settings: a microphone selection does not add a camera to a scene. See the Streamlabs Broadcast integration guide for its documented source workflow.

Check permissions and verify the signal
Allow Streamlabs Desktop to access the microphone and camera when Windows prompts for permission. Streamlabs’ getting-started guide, dated July 22, 2026, covers these app permissions. Then confirm that Streamlabs is pointed at the virtual device in the right place: the Broadcast microphone in audio settings, or the Broadcast camera in the scene source.

- Only one effect needed: Leave unrelated inputs on their existing devices rather than changing them unnecessarily.
Troubleshoot common setup problems
| Symptom | First checks |
|---|---|
| Broadcast microphone is missing in Streamlabs | Confirm Broadcast is installed and that you selected Microphone (NVIDIA Broadcast) in Settings > Audio > Mic/Auxiliary Device 1. Check microphone permission for Streamlabs and that Broadcast has a physical microphone selected. |
| The physical microphone works, but its Broadcast effect is not being used | Streamlabs may be set to the physical microphone instead of the Broadcast virtual microphone. Select the virtual device in the appropriate audio input setting. |
| Camera does not appear or display correctly | Make sure the scene has a video-capture source set to Camera (NVIDIA Broadcast), allow camera access, and match the camera resolution in Broadcast and Streamlabs. |
| Virtual devices are unavailable on the PC | Recheck NVIDIA’s current operating-system, GPU, driver, and installation requirements. The requirements cited above may change as Broadcast is updated. |
| Audio conflict or persistent missing-device issue | Check permissions and device selection first. The published setup instructions do not establish one universal fix for every conflict or missing-device case; consult current NVIDIA Broadcast support information or Streamlabs’ integration guidance. |
Or let it run in the cloud
NVIDIA Broadcast processes a microphone or camera input for Streamlabs on your PC. If your separate goal is to keep a pre-recorded YouTube channel live around the clock, StreamNeo is a cloud service for looping uploaded videos on YouTube: upload a recording or build a playlist, add your YouTube stream key, and go live. Nothing has to stay on at home; there are no quality tiers up to 4K 60fps, and the uploaded video streams as made. StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card, and the Monthly price is $9.99 per month. It streams uploaded videos to YouTube, not camera video. Learn more at StreamNeo, or start the free day.
