Suggestions from long experience with Linn DSMs + Roon:
- “Linn streaming” is the connection method you want. It has to be enabled by setting “subnet for Linn streaming” in Roon settings. That subnet must be the one that your DSM(s) are on. In my case, I have virtual dual-homing (for Tailscale) and I must make sure the subnet is the LAN where the DSM is, not the virtual WAN.
- Linn DSMs don’t get along with some managed network switches. Linn themselves recommend cheap Netgear unmanaged switches, which work. UniFi Flex Mini also works (although it’s managed). I currently use some refurb Cisco pro switches for their optical ports, but that’s not necessary.
- When Roon core is powered off for some reason, sometimes it does not re-discover the DSM. Power-cycle the DSM with the core up.
- The long-standing bug where Roon and the DSM got out of sync at the end of an album or playlist seems to have been fixed a while ago.
