I just saw that cameras now (in 5.4) can target different displays
By any chance, can you now have multiple connected headphones/speakers and send sounds to them separately?
The project I am making would split the screen in 4 different games, and i’d like for each player to be able to listen to it’s sounds separately.
I tried searching for solutions for this, and it always came as ‘impossible’, however, I just downloaded 5.4 and saw the target display settings for cameras, so I though that it might be possible now
It’s impossible. This is not a unity shortcoming as much as an OS shortcoming. As far as the OS is concerned, there’s only one audio output enabled at any time, so it only exposes one to Unity. Even if you had 4 sound cards in your computer (one for each headphone), Windows only shows one as “default”, which is the one Unity ends up using.
You might be able to change change the default audio device during runtime using a native plugin, but as far as streaming audio to 4 different outputs? I don’t think that’s doable.
