KEF LSX a Nightmare on Roon Network

Mac OSX 10.14.6
Roon build 416

Description Of Issue

  1. To play over LSX directly i have to start a track playing to them over airplay. Only after that does LSX direct come up as a zone option in Roon.

  2. Every few tracks it stops at the start of the next track. It loads the track but I need to press play to continue playing.

Is this Roon or KEF’s issue?


Hello @Hugo_Sharp,

Do you experience this issue with other playback zones on your network? If the KEF LSX is the only device exhibiting this behavior, it would appear that your Roon installation and configuration are in good shape.

Have you updated your KEF LSX to the latest available firmware? Do they exhibit this behavior when connected using a wired network connection?

Hi John, yes all up to date and no issues with any other zone. My annoyance is definitely with KEF, it’s been the only trouble child with Roon. It’s fully cabled via ethernet now.

Do you use the KEF’s with other inputs also? because:

Using AirPlay first sounds like a hack to make the KEF’s switch input.


I use the KEF LSX every day in my Roon system without any problems. I can also use several zones via Airplay 2 (eg KEF LSX and Bluesound).
Works with me via LAN and WiFi.
For the LSX a new firmware came out. This should certainly be updated.


Hi @Hugo_Sharp,

Have you tried factory resetting your LSX speakers yet? I have seen a few reports when factory resetting KEF speakers helped sort out some intermittent issues, it’s worth a try if the behavior is still the same since connecting them via Ethernet.
