What about Dual LAN mini PC’s? If I buy one of those and install ROCK, would it work in this scenario? One Ethernet cable to a router/switch, and another to a Roon endpoint.
No one can give you an answer unless they have already done this. The Roon team probably won’t have. However you can still load a Linux distro and do it that way. You can try the MOCK thread or gamble with ROCK and fall back to Linux if you can’t make it work.
