I’m having the same audio dropout issues, and have been communicating with rebeka. After further investigation, it seems to be a RAAT issue with certain endpoints.
I’m having dropout issues (radio, Tidal & local library files) with the Devialet D250 PRO “Roon Ready”, which is my main 2Ch system. It starts around 5 to 10 mins into play, once it started, it keeps repeating randomly every few minutes, sometimes multiple dropouts within a song, which makes it unusable.
However, there seems to be no dropout issues with Meridian M218 and Devialet AIR endpoints which are on the same network. It’s strange since Devialet AIR input works on the same Devialet D250 PRO device, which seems to point to some issues with Roon 1.8 RAAT protocol with the Devialet Expert “Roon Ready” endpoint.
