How to Livestream only the Master Audio
When livestreaming, you want to stream only the master audio and not the cue audio. Here are the steps to route only the master audio using OBS.
Go to your Tribe > Settings.
Set your Master Output to something other than the Rift, e.g. Speakers.
Go to OBS.
Add an Audio Output Capture Source and set it to the same device, e.g. Speakers.
Make sure that only that device is active during your livestream.
