So my case such - I have a gaming console with an audio output and an M1 MacbookMacBook, and I want to be able to use built-in Macbook speakers as an audio output for external device (console) while also playing audio from MacOS.
AFAIK speakers and 3.5mm jack are considered different devices in MacOS, so maybe there is any software that allows mixing input from 3.5mm jack to the sound from built-in/bluetooth speakers (using simple aux cable)?
If there is no such programs, do you think it is theoretically possible to do something like this?
