If I have lots of devices, I can connect them to a single speaker using a mixer. If I have lots of output devices (e.g. I have a speaker, a set of headphones and a 'party speaker'), I can pick between them using a 3.5mm hardware switch.
Is there any tool that can let me connect / mix multiple inputs to multiple outputs? For instance, it'd be ideal if I can switch from my headphones to my speakers at a push of a button. And it would also be useful to be able to connect my Switch / Desktop to my headphones at the press of a button. There'll never be a situation where I'm wanting to use multiple output devices at once.
At the moment, I have to plug in / plug out lots of wires to do this, which is a massive hassle. Any ideas on solutions?
Here's a quick diagram:
