GEAR is Nucleus rev b, Linn DS Majik, Marantz Cinema 50, Musical Fidelity M6s
Describe the issue
After a period of time (could be half HR or longer) playback stops for a second then resumes and from then on it keeps stopping and starting constantly. I have just upgraded to a nucleus rev b (with all music stored on its internal storage), because this issue was happening to my nas setup. Only way to rectify is to restart server, but issue will always returns
Describe your network setup
NF18ACV modem both Linn DS Majik and Nucleus rev b ethernet into this unit. 2 x D-LINK DGS-100BA switches around rest of house.
This sort of issue always suggests network issues to me.
Does it happen more often with streamed (Tidal/Qobuz) content compared to the locally stored content? Streamed content loads your network more.
Do you have any USB DACs/headphone amps ro whatever that you can connect directly to the Nucleus (and thereby elliminate the vast majority of the network dependency)? If so can you play reliably to the USB connected endpoint.
Have you got some alternative ethernet cables that you can try - even on a temporary basis (any cable will do - as long as it is CAT5e or better)? If so try replacing the Nucleus to NF18ACV cable and see if that makes a difference. If it doesn’t make any difference, then try replacing the cable between the Majik DS and the NF18ACV. Does that make any difference?
Try using difference ethernet ports on the NF18ACV. Presumably four are available - maybe one port has developed a fault. If, for some reason, you can’t do this, you may be able to try using a switch placed near the Linn and Nucleus with one connection to each of the Linn, the Nucleus and the NF18ACV. This would mean that the NF18ACV modem/router would not be involved in the transport of the stream from the Nucleus to the Linn (although it would still be involved in the overall Roon setup - remotes, streaming, endpoing discovery etc).
Thanks for sharing your report! I wanted to check in and see if @Wade_Oram’s helpful response above led to any success?
If no, please share the specific name of a track played when you experience the issue again. We’ll activate diagnostics on your Roon Server to take a closer look.
Hi Benjamin, I have tried all the suggestions that Wade gave me, (much appreciated Wade) but still no joy. I also switched from Ethernet to send signal via airplay when it was happening and over airplay the problem was gone.
I have just started playing music this morning and it’s really bad. Playing album from The Hu (from Qobuz) The Gereg. Also going to change to local file Marillion, Marbles and the problem seems to have gone. This is what usually happens, but it will come back even with local files.
I have turned off all MUSE filters, but once I turned them back on straight away it started. I have switched to another album, Nine inch nails, the fragile, somewhat damaged. Half way through I put MUSE back on.

We’ve taken a closer look at diagnostic logging and can see “broken pipe” errors reported by RoonServer in the Songcast audio stream to a Linn Majik DS. These occur around playback of the tracks you mentioned in your previous post.
This particular error indicates that the Songcast connection between RoonServer and the specific Majik DS in use as a Zone has been closed on one end, forcing the buffer to stop.
This issue does not occur with Airplay or other protocols in the logs. What Linn subnet are you using in Roon Settings → Setup? Are all the devices on the same subnet?
RoonServer also reports timeouts when downloading content from Qobuz’s servers, indicative of bandwidth allocation issues in the upstream connection.
Try hardwiring one of these Majik endpoints to the main router alongside the RoonServer machine, bypassing the unmanaged switch entirely.
Hi guys, I have done what you said and had quite a long time with no problem, but 21.56 Sunday 4/8/24 on Stevie Ray Vaughn, Couldn’t stand the weather, it all turned again and was unlistenable from then. Constant stop/start.
All devices on same subnet and nucleus and Linn Majik plugged directly into modem and not unmanaged switch.
Cheers Russ
A possibly redundant question, but did you try a reboot of your modem/router? => unplug completely, wait a few minutes and then restart the entire network.
Thank you for your patience. Our team has investigated around the timestamps you’ve submitted. During “Couldn’t Stand the Weather,” the prebuffer from Qobuz timed out repeatedly after the router allocated insufficient bandwidth to download the track.
There are additional contextual traces indicating a poor upstream connection to Qobuz’ servers.
Two suggestions:
Try changing the DNS server in your router’s web administration page to a known, reliable server. We recommend Cloudflare, 1.1.1.1.
I believe the router you’re using has a setting called “Traffic Scheduler.” This might be responsible for throttling RoonServer’s connection at certain times of day. I’d investigate whether you’ve activated this setting or have any scheduled rules in place.
We’ll keep an eye out for your response to provide further assistance. Thanks!
I have checked router and Traffic Scheduler is not enabled, and have also changed the DNS server. Hopefully you won’t hear from me again. If not, thanks for the help, and Roon is awesome.
