2 Amplifiers, 1 set of speakers

[Cabanon]

Hi All,

I'm in need of help regarding my future basement setup. basically, I'll have 2 identical TV on the wall side-by-side, one for me when I play/watch movies and the 2nd one for the kids when they want to do their thing. I'll have 2 amplifier, one on each side that will have multiple video games console (about 13 total lol) connected, all the retro on one side and all the modern on the other one.

Where the fun/headache is, I only want one set of speakers (5.1 setup) in the room. Having 2 speakers side-by-side or on top of each other would look weird and wonky so it's out of the question. I will use wireless headphones when both TV are used while the other TV uses the surround setup.

Is there available for switch this particular setup ? I found some for 2 speakers but not for a complete 5.1 setup. I'm to the point where building a switch myself is my last resort.

thanks all !
