I am running my PS5 on the same desk as my PC and I am still looking for a solution to the audio output. Currently I am using Bluetooth for the PS5. But my ideal solution are speakers that I use for both the PS5 and my PC that allow me to simply switch between inputs. Bluetooth audio sucks ass in terms of UX when you run multiple devices and I really want something more convenient. All the stuff I find on Amazon looks like shit, i.e. exactly what I have right now.

Is anyone here running a similar setup and has solved this issue?

Update: I found the Sound Blaster G8 and I must say that Sound Blaster still delivers. It supports two inputs, where both can be USB, which was my use case. One USB doubles as power supply, so you don't need another cable. And then both PS5 and PC just recognized the G8 and it worked immediately after plugging it in. Really cool. And because it has an optical out I could repurpose an old soundbar to replace the old active speakers. I am thrilled, this exceeds my expectations.
