ROCK doesn’t support the Thunderbolt port at all… You’ll need to use a proper distro.
Also, for Roon usage, 10GB Ethernet is totally unnecessary… Max bitrate for a single zone is around 50Mbit/s, and thats with upsampling to 768k. That will stress the CPU hard enough that you’ll run out of CPU for multiple zones long before you exceed a 1GB link…
I copy huge amounts of data around my network for testing all the time. I don’t like to wait when I don’t have to. If I can get a 10x boost in speed for this, I do it.
Last year @danny mentioned going to the 5.x kernel soon. I’m wondering if this happened because if it did, support for this should be baked in.
