Interesting. One other option is to use OrangePi for the server. OrangePi has ARC over HDMI and that would count as an input.

I did choose the WiSa surround sound system linked. I’ll cannibalize it later to make better speakers. I like it because it is audio at 24 bit/96kHz. It also just uses the HDMI ARC.

Radio signal(I’m a comm/nav aircraft mechanic, I had to know):

• 5 GHz spectrum
• Fixed latency of 2.6 ms

Straight up, that is awesome. I absolutely love it.

Well… From the very small amount that I’ve gathered from balenaSound, timing is mostly handled. If the software I want to write for it becomes a thing, then the Server PI will have a microphone to detect how much latency there is and adapt. That is a step way down the line though.
