On MacOS High Sierra 10.13.6, I want to output two separate Chrome browser tab applications to two separate devices from my single macbook pro.
1) Chrome tab 1: browser game --> outputs to headphones
2) Chrome tab 2: youtube video --> outputs to HDMI-connected TV audio
I'm struggling to set this up in AudioMIDI setup.
To set up the input, which is the logitech headset microhpone, I set the aggregate device as input:
And the display port (TV via HDMI) and Headset as output in the Multi-output Device:
The problem is, the same audio streams are aggregated from all sources (youtube video, and browser game) to output to both the TV and headset.
What I need is two separate audio streams going to two separate devices.
