It is still a Devialet issue that needs to be resolved. Submit tickets to Devialet support. The only alternative to use Roon RAAT is to resort to a 10/100 mbps switch in front of the Devialet or use WiFi which is what I’ve been doing since Devialet first released their support for RAAT 20 months ago.
The recent update from Devialet eliminated the “audio files loading slowly…” error but the dropouts are still unacceptable if streaming hi-res music on gigabit Ethernet.
