Describe the issue

I have been experiencing this problem for awhile now. Quantum Fiber 1gb service >ONT>Netgear switch(replaced twice)>Nucleus Plus (Rev B)>Mcintosh 611 mono blocks> Mcintosh C2700>Linn Selekt DSM. All ethernet connected. When accessing an album or track it takes an inordinate amount of time before coming up, generally 1-3 minutes, it will just buffer, for lack of a better term, during this waiting period, especially now in the new "Smart Playlist" option. It also affects when playing a queued playlist and a track ends it can take awhile for the next track to start. I have had a lifetime subscription for about 3+ years and am aware most problems are network related, this is not the case with this issue as I have done my due diligence, IE; checking and changing wires, speed testing, switching network switches, rebooting and power cycling the Nucleus+ on and off. Any help in resolving this issue will be greatly appreciated. Thank You

Hi @Robert_Zinn,
Thanks for reaching out to us about this issue. I activated diagnostics on your account. Looking at the logs from this diagnostic I’m not convinced that this isn’t network related. I found multiple traces showing requests timing out and 502 errors. The 502 error points to an issue either on the Qobuz servers or with your ISP. Usually an issue like this would get resolved without you needing to do anything. Has this issue been continuing on for multiple days?

Thank you for the response, yes this is an ongoing issue most every time I use it, however I neglected to include, if I I were to listen to a complete album the tracks in order, it plays flawlessly one right after another immediatley if this will help. The issue occurs constantly only were I to make a playlist with various tracks, artists, and different sources such as Tidal, Qobuz, or from my library stored in QNAP TS-251+. If you were to go back in my support posts you will see it has been going on for years without a fix. I switched from COX ISP to Quantum where I am now. The issue has been occurring from both ISP’s. I am pretty well convinced the issue is the LINN not communicating well with ROON, though this is why I came to you again. I did have Quantum come to my home many times to check my internet and all was in good working order, I have no tv streaming issues or connecting to the internet. What’s puzzling to me is as previously stated when using both the LINN and KAZOO apps everything works flawlessly, only when using ROON does this issue happen. The time out may be because the LINN takes 20 seconds in playing the next track then the read out disappears, comes back when track starts playing. Should you require any further information please don’t hesitate to let me know.
Thank you

We’re having the same problem. It’s erratic, has been getting worse over the past couple of weeks, happens several times a day now and delays can last from roughly 30 seconds to many minutes - minutes (2 to 15 or 20) is much more common than seconds. The delays happen when opening an album, playing the album, playing a solo track, launching a playlist or moving from one track to the next on an album or playlist. We have Cox 1GB service (typically between 700 and 800 Mbps download). Have no issues with any other streaming or internet activity. Also a lifetime sub but it’s gotten to the point where Roon is virtually unusable unless we get lucky.

I’ve gotten to the same point where I find it unusable. What streamer are you using?

We’re using a Nucleus+.

Sorry that’s the core, my streaming device is Linn SelectDSM, yours?

We don’t use a dedicated streamer. We stream from Quboz and play our purchased content from several storage devices on our home network all through the Nucleus+.

Some info that may be useful. Laptop running the Roon UI connected to input port on Nucleus+ (WiFi connection produces same results). Opening an album on either Quboz or the drive installed in the N+ takes about 40 seconds. Takes another 40 secs or so for the system to recognize the Play button has been clicked. Takes an additional 40 seconds or so for track 1 to play from internal drive and 1.5 to 2.5 mins for play to start from a Quboz album. Moving from one track to the next sometimes takes a very noticeable amount of time and sometimes doesn’t. Using an Orbi CBR 750 router with a wired connection to the N+ and “Disable IGMP proxying” unchecked. Roon is allowed through Windows 11 firewall with TCP ports 9100-9200 and UDP port 9003 enabled for input.

I had the ORBI and found it to be unreliable. I now have the EERO with 1 satellite which my DSM is hard wired to. Best router I’ve ever had.I tried ROON on laptop and it was awful, got NucleusPlus which is exponentially better. Remotes on laptop win 11, IPad 7th generation, and Samsung Note 9 cell.

I think we’ve solved the problem. Please keep in mind that I don’t know enough about firewalls or routers to reason to a solution so I’m just following instructions. (Perplexity was a great help here as it returns bulleted lists of possible causes of a problem and step-by-step solutions based on reliable sources - often Roon’s help pages in this case - without having to search multiple sources and dig out answers to your questions from what you find.) I reconfigured the router in accordance with Roon’s instructions, reset Roon to pass through the Windows 11 firewall and re-enabled the required TCP and UDP ports. It didn’t solve the problem. Before doing all this I’d cold-booted the router and the Nucleus+ which also hadn’t solved the problem. Cold-booted the N+ again after everything else was finished and Roon has performed flawlessly for 2 days with no significant delays. Hope this helps.

Funny you say that, about the same happened to me. Played fine today for about 3 hours.
TCP and UDP are both enabled.

One day later
SAME ISSUE!

Hey @Robert_Zinn,

Apologies if this has been glazed over, but do you run into performance issues when not using the Linn?

Give your router and Nucleus a reboot, then reproduce the issue when playing to the system output of one of your remote devices, like your windows 11, and share the date, time, and track playing. We’ll take another look from there. Thank you! :+1:

Thank you for your response.
After rebooting all devices more than several times it has worked well over the last 4 or 5 days. I have another streaming device, Aurender, which worked flawlessly using their app, also when using thd Linn app or Kazoo app again works flawlessly, when Roon isn’t. I’ve come to the conclusion, at times the Linn and Roon for whatever reason doesn’t communicate well. When this occurs the other devices and apps work fine, so I’m pretty well convinced it’s a communication error between Linn and Roon. Please feel free to correct me if you think otherwise. This has been an ongoing issue for a couple of years but got better when Linn went from Roon tested to Roon ready and RAAT was installed. Just to reiterate no issues ever on other devices or apps. I have wanted and suggested several times I wanted to pack up my NucleusPlus and send it off to you for an in depth diagnosis. I had a networking tech come out and check and he found all to be well, even when the issue was occurring.
Thank you

At approximately 2:15pm PDT today, OCT. 31, while playing from a mixed que after a Chris Botti track finished next track being a Tidal selection of Ray Charles “Georgia”, Took about 5 minutes to begin. My remote is a Lenovo laptop using win11 OS. Then after playing 2 tracks back to back from same Ray Charles album, again Roon stopped for about 2 minutes before next track started. LINN and Kazoo app worked immediatley when prompted during the time ROON would not respond. After the 2 minute pause went back to playing as it should so far after 3 tracks. After those 3 tracks again another stoppage for an extended amount of time. At approximately 2:45 I rebooted LINN, after approximately 2 minutes of trying to continue it started up again. Aurender, LINN, and KAZOO apps all functioned well. I’m seeing in the logs “dirty playlist” if this will help. I think you get the idea. If you require anything further please let me know.
Speed at time was fine,(see attached)


Hey @Robert_Zinn,

Thanks for the additional information, I think there was a bit of miscommunication in my prior response.

We weren’t asking you to use different audio streaming software, but rather, testing out different endpoints outside of the Linn device, as that seems to be the source of your issue.

Just to be clear, were you using the system output of your Lenovo remote when this occurred? Or, were you streaming to the Linn device using this remote? From your report so far, we cannot conclude the issue is tied to the Nucleus specifically, but rather -

I agree with your conclusions here.

From a recent diagnostic report, we’re seeing fluctuations in network bandwidth in relation to the Linn device around the timestamp you’ve provided.

Do you experience the issue no matter the file format?

Can you set your Linn device up to your primary router, along with your Nucleus?

I really don’t have another “Roon ready or even Roon tested” end point. I’m not disagreeing with you pointing the finger at the Linn device. I have contacted Linn in the past who point the finger at Roon as the source of my issues. I’m in a catch 22, any suggestions? Both the Linn and the Nucleus have been directly connected to my router with no improvements, regardless of formats.

Hi @Robert_Zinn,
We spoke to the developers about your case and they had a few questions to help them track down the origin of the problem.

  1. Do you make regular use of the folder browser feature?
  2. When you restart Roon does it take a while to have this performance issue occur?
  3. If the answer to question 2 was yes; Does it return if you don’t use folder browser at all?

No I don’t make use of entire folders to put in que and play other than selecting a track from them to add to the que of tracks I have selected from various locations such as Tidal, Qobuz, Albums, tracks, or my local library located on my QNAP T-251. This is how I do a majority of my listening, creating a que from various locations. There is no pattern for these problems to occur. When I reboot the Nucleus+ I can usually get good performance, sometimes for awhile, sometimes not, but at some point the issues reoccur. For instance I am playing now, 11/15 @ 1pm pst, some tracks which can take 20-30 seconds to start after the previous one has finished, sometimes there are immediate switches to the next track. The problem is at it’s worst when, while playing queued tracks, if I were to add another track “next” It can take an inordinate amount of time for ROON I guess to find it and begin or if I choose to skip a track and ff to next. I should add if I were to play a complete album tracks DO switch immediatley. Others have given up on ROON with this problem and gone to use the LINN or KAZOO apps with no issues at all as is the case with me too, however, not only do I have a lot invested in ROON which I don’t want to dispose of, I still believe when working as it should it is by far and away the best audiophile program anywhere so to me it’s worth my effort to try and resolve this issue. I also am in contact with LINN support.
Thank you for your continuing efforts trying to resolve this ongoing issue.
