Sound quality - Roon RAAT vs Roon Air

[Saint0]

I just updated to Roon 1.8, and have been having audio dropout issues (streaming radio, Tidal and local library files). It starts around 5 to 10 mins into play, once it started it keeps repeating every few minutes, sometimes multiple dropouts within a song, which makes it unusable.

However, there's no dropout issues with Meridian M218 and Devialet AIR endpoints which are on the same network. It's strange since Devialet AIR works on the same device, which points to Roon 1.8 RAAT protocol issues with Devialet "Roon Ready" endpoint. Has anyone noticed the same problem?

What is your network configuration/setup? Ever since the last Devialet firmware, I have had zero dropouts using RAAT, regardless of file size, source (NUC/NAS or NUC/Qobuz) or format.
Everything in  my network is wired and in the same room as my main system. Everything is on a single Gigabit switch. My second system (home office) is 2 floors up and connected via Mesh wifi6. Also there zero dropouts even with DSD256 files. Both Roon and Devialet are sensitive to network issues, even if nothing else on your network indicates problems. Endless posts on the Roon support forum all end up being about network issues (Roon not liking a particular configuration or a particular piece of hardware in the LAN setup).
If at all possible, run a wired setup in your LAN and check for dropouts. If you still get them, try a different switch (nothing fancy - no need for so-called audiophile network switches, which do nothing anyway).

I had no issues with Roon RAAT since the last Devialet firmware update until I updated to Roon 1.8
