Tools You’ll Need

• OBS Studio
  
  

• BlackHole 16ch (free audio driver)

Step-by-Step Setup (Mac)

1. Route All Audio to OBS

• Go to: System Settings → Sound → Output
  
  

• Select: ✅ BlackHole 16ch
  
  

This sends your desktop audio into OBS — but you won’t hear it yet.

2. Create an Aggregate Device (Mic + System Audio)

• Open: Audio MIDI Setup (Cmd + Space → search)
  
  

• Click ➕ → Create Aggregate Device
  
  

• Tick:
  
  

  • ✅ BlackHole 16ch
    
    

  • ✅ Your mic (MacBook or USB mic)
    
    

• Rename it: OBS input device
  
  

OBS now captures both mic and desktop audio.

3. Create a Multi-Output Device (So You Can Hear Audio)

• Still in Audio MIDI Setup:
  
  

• Click ➕ → Create Multi-Output Device
  
  

• Tick:
  
  

  • ✅ BlackHole 16ch
    
    

  • ✅ Your headphones (or speakers)
    
    

• Enable Drift Correction on your headphones
  
  

• Rename it: Hear game

Sends audio to your headphones and OBS.

4. Set Mac Output to the Multi-Output Device

• Go to: System Settings → Sound → Output
  
  

• Select: ✅ Hear game
  
  

You now hear the game, and OBS captures it too.

Important Tips:

• Adjust headphone volume before switching to Hear game
  
  

• macOS may lock low volume; if so, switch back, turn it up, then return to Hear game
  
  

• Avoid changing output devices mid-stream — it may cut the audio until refreshed
  
  

5. Configure OBS

A. Video

• Display Capture → name it “Game” → select your screen
  
  

• Video Capture Device → name it “Webcam” → select your camera
  
  

• Resize and position as needed
  
  

B. Audio

• Audio Input Capture → name it “Mic + Game”
  
  

• Device: OBS input device (your Aggregate Device)
  
  

6. Fix Mic Echo / Silence

• OBS → ⚙️ Mixer Settings → Advanced Audio Properties
  
  

• Set:
  
  

  • Mic + Game → Monitor Off
    
    

  • Mic/Aux → Monitor and Output
    
    

Ensures mic is audible on stream, without echo in your headphones.

7. Configure StreamrTV

• In StreamrTV broadcast setup:
  
  

  • Camera = OBS Virtual Camera (start it in OBS)
    
    

  • Mic = BlackHole 16ch
    
    

This combines your mic and system audio into one stream input.

8. Browser Game Fix (Mac)

• Play the game in: Safari
  
  

• Run OBS + StreamrTV in: Chrome (or a different browser)
  
  

Prevents audio cutouts when browser tabs lose focus.

Stream Game + Webcam + Mic Audio on PC 

Tools You’ll Need

• OBS Studio
  
  

• VB-Audio Cable (free virtual audio device)

Step-by-Step Setup (Windows)

*These instructions are AI generated and are in draft form and have not been widely tested. Please follow at your own discretion. If you encounter issues or know of better methods, we’d love your feedback to improve this guide.


1. Install VB-Audio Cable

• Download & install VB-Cable
  
  

• Reboot your PC after install
  
  

Adds a virtual audio device (CABLE Input) to route audio through.

2. Set VB-Cable as Default Output Device

• Go to: Settings → System → Sound → Output
  
  

• Set default device: CABLE Input (VB-Audio Virtual Cable)

Sends all system/game audio into the virtual cable for OBS.

3. Set Up OBS Audio Sources

Game/System Audio:

• Audio Input Capture → name: “System Audio”
  
  

• Device: CABLE Output (VB-Audio Virtual Cable)

Microphone:

• Audio Input Capture → name: “Mic”
  
  

• Device: your mic (USB or built-in)
  
  

Optional: Combine in OBS or mix via VoiceMeeter.

4. Monitor Audio Locally

You won’t hear your game by default when using VB-Cable.

To fix:

• Go to: Control Panel → Sound → Recording → CABLE Output → Properties
  
  

• Listen tab → ✅ “Listen to this device”
  
  

• Playback device: your headphones/speakers

Lets you hear everything while streaming.

Some latency may occur — VoiceMeeter can reduce this.

5. Configure StreamrTV

In StreamrTV:

• Camera = OBS Virtual Camera (start it in OBS)
  
  

• Mic = CABLE Output or VoiceMeeter Output

Sends combined mic + game audio to StreamrTV.

6. Browser Game Fix

If audio cuts out when the game tab loses focus:

• Play game in: Microsoft Edge
  
  

• Run OBS + StreamrTV in: Chrome or Firefox

This prevents tab focus issues.
