Description Of Issue


Since start with Roon i have often problems with playback music for a longer time. The music plays sometimes one hour, sometimes 20 minutes sometimes some minutes and then stops. When te music stops, the DSD/signalpath keeps saying that the processing speed is about 70-80 x.

I’ve tried everything; go on ethernet, go on wifi only, new ethernet cables, ethernet from KEF LSX to a switch, ethernet to my router, new router system etc. Nothing works!

Hope someone can help me…
