Airplay as separate video display -- how to also have separate audio?
May 5, 2019 1:46 PM Subscribe
Through Airplay on a MacBook Pro, I'm using a TV as a separate video display. This allows me to play one video on the MacBook's screen and a different video (playing in a different app) to stream to the TV. But this doesn't play the accompanying audio for each video separately on the two devices (I'm using a 2018 MacBook Pro and an Apple TV 4). How can I do this?
I think this should be possible on Macs featuring the new T2 chip, which seems to allow two distinct audio outputs, but I can't work out how to configure this. Would it involve using the Audio MIDI setup utility? I've read that Rogue Amoeba's Audio Hijack might be able to do this, but I'd rather not use a third party for a task that could be possible to accomplish natively.
If it's relevant, the reason I'm doing this is because I'd like to have a live event that's streaming in a web browser to play on the TV with Airplay, while also doing some light editing of audio/video clips on the laptop. This live event is not available on any Apple TV apps.

Have you tried using VLC's "Audio Device" menu to set the audio output device to the built-in speakers (or headphones) while the system default is set to the TV speakers?
If the "light editing" you have in mind is mostly cutting and splicing, VLC could be useful for finding time offsets even if the editing program does not support audio redirection.

Pro audio apps usually do give you the output routing choice, but I don’t know if the AirPlay route is exposed as an independent output that can be controlled or if it always hooks into the system audio bus.
Wish I had a better answer than “technically, probably, but I can’t give you steps or an app to use to do it. “
