Is there any way (or application/driver for this) to play audio from app to multiple output devices? Or even better – to just duplicate/mirror audio that is coming to one output device to another one.
I have found something like this:
https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/output-audio-to-multiple-devices-in-windows-10/b284def2-d684-4f1f-87a0-f562f556aedd
But I can't use it because I use bluetooth so my default windows output device always says "not plugged in", so I can't even confirm what it does.
My final goal is to redirect music application to both my headphones and virtual cable.
