Send video and audio from OBS Studio to Playback

You can use live streaming apps like OBS Studio to produce a video and audio feed for Playback. This allows you to capture video and audio from applications outside your browser create a custom video production.

For this tutorial, we are using OBS Studio. You can follow similar steps using other live streaming apps with virtual camera support (e.g. Streamlabs OBS, vMix, Ecamm Live).

Send audio from OBS

  1. If you are using OBS to capture audio, do not use Desktop Audio Capture.
    1. If you use desktop audio capture, OBS will capture audio from Playback and it will ruin your sound.
    2. Instead, use Application Audio Capture to capture audio from specific applications where you are not using Playback. e.g. Use Playback in Safari and capture audio from Chrome.

  2. Install a virtual audio device on your computer
    1. Install VB-Cable or any virtual audio device that can receive and send audio between applications.
      1. Note: To install VB-Cable on PC, you’ll need to run the installer package in administrator mode. Right click the installer program and select “run as administrator.” Then you will need to restart your computer.
  3. Select VB-Cable as your audio monitoring device in OBS
    1. In OBS, go to Settings > Audio > Advanced and select VB-Cable as your Monitoring Device. If VB-Cable does not appear in the device list after your first setup, you may need to restart your browser or computer (likely for PC).
