Running the Roon Core on a Synology DS720+ with extra memory. Roon Core running on SSD.
Have several Sonos zones and a couple of non-Sonos zones; no DSP.
When running the two commonly grouped Sonos zones (kitchen and living room, and nothing else), often the living room will miss the first few seconds of a song, then picks up (in synch with kitchen which does not miss). Living Room is Sonos Port connected to preamp; kitchen is a pair of Sonos Play 1’s. All new (2020 and later). Living room is ethernet, kitchen is wifi.
