Description of Issue

When using the NUC5i3 as an endpoint, I often have momentary drop outs sometimes resulting in loss of the connection to the core and sound for a couple of minutes. See photos. When connection to core is restored the playback had to be restarted manually. This occurs randomly - sometimes everything is ok, then it can happen several times in one track.

Yet when playing stereo files on Linn Klimax DSM everything works fine

Are the linn and the nuc on the same switch?

[Newton_John (John Trewhitt)]

Yes, at present. I’ve also attached it to another switch near the router. Same issue occurs with both positions.

From time to time I experience a similar issue. The rock core running on my NUC was very stable until a couple of weeks ago. There is no wifi involved, all is connected over wired network. I think it started after the last update to release 943…

Hi @Newton_John ,

When this issue occurs, do you also notice RoonServer restart on the Web UI? We are looking into an issue where Linn devices can cause issues on RoonOS devices at the present time, if your RoonServer looks like it is restarting when you notice the connection drop, it is possible that it is the same issue as the one we are investigating.
