Connected Audio Devices

Several, including Sonos, Naim Uniti Star, KEF LSX, and M1 iMac

Number of Tracks in Library

Local library = 5,459 tracks, stored on a Synology NAS

Description of Issue

All has been fine for many months, but recently if I start any music via my M1 iMac to play on the KEF LSX the music stops after ~28 seconds. If I press Play again the same things happens after a further 28 seconds. If I use the Roon app on my iPhone to control the music it works fine.

The same happens whether I try to play music via Qobuz or a locally stored file.

Playback on the Naim Unity Star is fine.

Any ideas how to resolve this? Many thanks!

If after careful reading all the advice of the team and the community is followed, only improved program code will help. Roon is very demanding in terms of network solution and there are individual problems in the per mil range, which then can be solved only with protocol exchange to the team.

I think this is already done:

Disconnect all devices from the network and power. Waited a few minutes, slowly restarted everything from the router. IPv6 switched off, DNS adjusted, everything wired…

If the lsx are wireless they are very sensitive to drop outs seemingly, going by the number of posts here.

28 sec reproduction sounds odd. A license cut out maybe

Your iMac is not at current release state, maybe upgrade to see if that causes hiccups…

Many thanks, All.

I just logged out and logged back in to Roon on the iMac, and it tried to download an update … but never completed the task; after many minutes it said “There was an error checking for an update”.

The app remains on 1.8 (880) Stable.

I started to play a new track and after 29 seconds it stopped and showed the error “Roon lost control of the Audio Device”.

How might I “force” an update on the iMac?

FWIW, everything is connected via Cat5e - even the KEF LSX speakers - and I have a good internet feed (via Starlink).

TIA
