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
