You can also check this video for a more detailed tutorial of how the OBS plugin works, if you are curious.

Note that this video alone will not tell you how to use it like Audio Router would, you need my own tutorial for that. But it may help you get more out of the plugin.

Hello
This "OBS solution" is not as good as audio routeur. It takes all the memory and the PC is even not able to run netflix app properly. We need a solution patch from audio routeur ...

The monitoring device has a bit of lag, but hey, we solved an impossible problem that only the bright minds of android and Apple devs could solve
