Advice on USB-A dock for multiple gaming controllers, and

Hey everyone, just a re-post of a question posted earlier in the wrong section - Just wanted to share a setup I've been working on and ask for some advice. It started off when our family moved to a new house, and I mounted our QLED and Apple TV to the wall in the living room. When we moved, I cable-tied a cheap second hand Dell Optiplex micro-form factor PC to the back of the TV (all of these devices are hard-wired into our home network), and set the Optiplex up with a wireless keyboard and trackpad combo, which worked out great for WFH without a desk, and home admin type stuff. (I have most of my higher end gaming stuff, like the PlayStation 5 and the gaming PC, in my own office - again all that is plugged into the network via CAT6 patch cables; I try not to use wi-fi for non-portable devices) So I wanted to turn this into a gaming area for the kids where they could game without disappearing into Daddy's office..... we wanted them to be play able to be in the living room where we could keep an eye on them 😄 So when I got my iPhone upgrade, I had the idea of mounted the old iPhone 13 on the wall behind the living room TV, hoping to pair it with a PS5 Dualsense controller and mirror the screen to the TV. It was fine, but it was pretty laggy for some faster-paced games. So I installed the Steam Link app on the Apple TV, which let us stream Steam games really well, and pairing the PS5 Dualsense was pretty straightforward too. But obviously that's not going to work for actual PS5 games So I thought... if I want them to be able to stream PS5 games to the living room using an actual PS5 controller and also stream PC games using an Xbox controller, I'm going to need to pick up an Xbox wireless controller and the official dongle. https://www.amazon.co.uk/dp/B00ZQW91DE?psc=1&ref=ppx_yo2ov_dt_b_product_details And I also added an 8BitDo wireless USB adapter to connect the PS5 controller to the Dell OptiPlex. https://www.amazon.co.uk/gp/product/B01NCLG45T/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 So in theory the Dell OptiPlex should be able to stream anything they want using the appropriate controllers, at this point. The first problem is that the Optiplex only has two USB-A ports, which isn't enough for the 8bitDo receiver, the xBox wireless adapter, and the USB-A dongle for the work keyboard/mouse. Was just wondering if anybody could recommend a powered USB-A dock that has low latency and broad compatibility with these types of controllers The other problem is that when streaming PS5 gameplay to the Optiplex (using the PS5 remote play app from the Microsoft Store), there's a persistent buzzing noise on the audio. I thought at first it might be because there was some electromagnetic intereference on the CAT6 patch cables here, but other streaming methods like Steam Link on the Apple TV didn't have that issue. Interestingly, when I streamed from the PS5 to my own office gaming PC and Parsec'd from the gaming PC to the living room Optiplex, the lag was actually slightly better (compared to PS5>Optiplex direct connection), and the buzzing actually reduced somewhat. This makes me think it might be due to the PS5 remote play software, or maybe the Optiplex just hasn't got enough under the hood for that method So to sum up a very long post 😄 I've tried: 1) Streaming PS5 to an iPhone and mirroring to the Apple TV (very laggy), and there is no PS5 remote play app for the Apple TV (yet) 2) Haven't tried the chromecast PS5 app yet, which would use wi-fi but would have a direct HDMI connection to the TV 3) Haven't tried tweaking the QOS settings on my network setup yet 4) Haven't tried other devices like replacing the Optiplex with a better NUC I'm really curious if anyone has found a good way to stream PS5 gameplay to another room without a second console. Also, any recommendations for a power USB-A that would work with that setup, would be greatly appreciated
