Does the issue happen with local library music, streaming service music, or both?
· *Only streaming* music is affected.
Please select the streaming service(s) with which you're encountering playback problems.
· Qobuz
Have you tried logging out and back in again to your streaming service in Roon Settings?
· Logging out and back in had no impact, the issue remains
Do you have an approximate timestamp of when the issue last occurred?
· 2:10 PM and earlier today. I had to switch to Lumin app to use my system
What are the make and model of the affected audio device(s) and the connection type?
· Lumin U1X , Apple Imac, Audio Research CD9
Describe the issue
Playing Qobuz on Roon stops after 30 or so seconds and skips to the next track. This happens on my imac, phone or ipad. My Lumin U1x plays perfectly with my library via Roon or Qobuz via the Lumin app

Classic case of Roon not seeing an authorized Qobuz login inside of Roon itself.
Please double check your credential’s at login, status of account inside of Roon.
Correct email address associated with valid Qobuz account.
We’ll need to inspect logs around that timestamp to confirm the particular reason for the dropout. The machine acknowledged our request, but RoonServer closed before the upload could complete.
However, @AceRimmer is correct that the symptoms listed match a Qobuz account authorization issue. Qobuz’s API will only deliver 30-second samples of tracks when an account is not authorized to play material due to (most commonly) subscription status or (less commonly) some account configuration issue.
Please navigate to the Qobuz web player or Qobuz app and verify the email you use there. Sign fully out of your Qobuz account in the web player and also in Roon Settings → Services → Qobuz. Then, sign back in via Roon, ensuring that its the same email.
A session can become deauthorized even if the email address is correct, so ensure you sign out/back into Qobuz within Roon.
Yes, I loged out and loged back in, same results. Crazy thing is, when I switched to a different album there was no issue. I also subscribed to Tidal too today.

No, not so crazy really.
It could well be that the version you have saved has now been replaced with a “different” version.
Qobuz would now see this older version as not available any longer and skip through the tracks in the manner you described.
Please check the versions.
Yes, logged out and logged in. This happens on a regular basis. Sometimes resolved by changing to a different album. I purchased Tidal again and don’t recall that issue with Tidal. My Library also plays fine. The best thing about Roon is the ability to discover a new album in seconds after reading an article or hearing a track from Roon radio.
Can you reproduce this issue when only playing audio to the system output of your Mac?
I see you have a few different machines running Roon Server - can you confirm you’ve logged out and unauthorized all other machines before starting up Roon on your latest setup?
Apologies, we’ve misinterpreted your symptoms as a Qobuz account authorization issue, since that causes playback to cease at precisely 0:30.
Reviewing logs, we see the actual cause of the dropouts is network-related and twofold:
slow downloads from the Qobuz API with files above 48Khz and
sample loss between RoonServer and the Lumin on the local network.
A few tests should help pin this down:
If you set the Max Sample Rate to 48Khz in the Device Setup for the Lumin Zone, can you reproduce the dropouts at all?
Turn the Max Sample Rate back up to the previous setting. Now lower the streaming quality for Qobuz in Settings → Services → Qobuz; can you reproduce the dropouts at all?
Please try playing to the Lumin Zone alone, ungrouping the Grouped Zone as suggested above.
I checked and logged out and in and still an issue. I even purchased Tidal hoping to resolve the issue but no, both are doing it on my Roon Server. But not on every title. Again all play well directly on the Lumin with the Lumin App
Thank you for taking the time to test. Roon’s proprietary audio protocols are uncompressed, which means that RAAT playback with high sample rates can be more vulnerable to WiFi interference and overzealous network management settings in routers or managed switches.
Diagnostics confirm that both the individual and grouped Zones to which you played back streaming content experienced dropouts for the following reasons:
slow upstream media. This error occurs when RoonServer isn’t receiving content quickly enough from streaming service APIs to keep pace with playback
sample dropouts between RoonServer and networked endpoints.
This occurs at high sample rates only (96KHz and above) from what we can see in logs - did you experience any dropouts when you restricted audio to 48KHz in Device Setup for the Lumin Zone?
We usually recommend the following in this circumstance:
Enter the router settings admin page and ensure that a reliable DNS server (like Cloudflare, 1.1.1.1) has been assigned.
Also ensure in the router settings admin page that any multicast forwarding settings are enabled
Test playback to the Lumin as an individual Zone with the sample rate restricted to 48Khz in the Device Setup. Don’t add any other Zones yet - try Qobuz first, and then Tidal, allowing Roon to downsample content before it distributes it across the network. If you can’t reproduce a dropout with this configuration, then slowly raise the Max Sample Rate back up in Device Setup until you can reproduce a dropout.
We have a few questions to help expedite our troubleshooting:
What is the router you’re using in this setup?
Is there any other network hardware involved?
Are any of the endpoints you have grouped with the Lumin relying on WiFi?
We’ll watch closely for your response. Thanks @Bruce_Weiser!
What is the router you’re using in this setup?
*** PLink AC5400 Tri Band WiFi Gaming Router
Is there any other network hardware involved?
I do not understand this question
Are any of the endpoints you have grouped with the Lumin relying on WiFi?
Every endpoint is hardwired to the router above, I do not use wifi for streaming
I have not tried to lower rate to 48, I prefer to stream in the highest rates
While listening today, I do not think the error happened. As I mentioned It seems to only happen on certain titles
I will have my son in law check on the reccomended router and other settings.
My sincere thanks to all who have taken the time to help.
My Roon audio system is the one of the most important things to me. It has given me a lot of musical and audio enjoyment, not to mention introducing me to dozens of new artists and albums!
We thoroughly analyzed the logs you provided and have pinpointed the cause of the playback interruption in your Lumin U1-X + Kitchen Lumin M1 zone.
The primary issue is insufficient network connection quality to maintain a stable stream of the high-resolution audio file.
Cause of Playback Stoppage
The logs indicate that the playback of Wonder Why (Live At Shelly’s Manne-Hole / May 14 & 19, 1963) in 24/192 Qobuz FLAC format was stopped due to the following reasons:
Poor Connection Warning from Qobuz: The system explicitly warned that the actual download speed was below the minimum requirement for the high-resolution stream.
The log shows: poor connection kbps:6479.0 (min:7316.0).
For stable 24/192 Hi-Res audio, a minimum of ≈7316 kbps is required, but your system was only consistently receiving ≈6479 kbps.
Excessive Audio Dropouts:
Due to the unstable and slow data flow, the LUMIN M1 endpoint started repeatedly reporting audio sample skips ("status":"Dropout").
The critical threshold was exceeded, leading to the system terminating the stream: Too many dropouts (>3s dropped out in the last 30s). Killing stream.
Track Stopped Due to Slow Media:
As a direct result of the dropouts and bandwidth issues, the synchronized zone stopped playback: Warn: [zone LUMIN U1 + Kitchen Lumin M1] Track Stopped Due to Slow Media.
In short, the stream was stopped because poor network quality (likely impacting your connection to the Qobuz server) caused too many dropouts on the LUMIN M1 endpoint.
To ensure stable playback of Hi-Res content (24/192) from streaming services like Qobuz, we strongly recommend focusing on network stability:
Check QOS and Set DNS Server:
Access your router’s administration page.
Ensure a reliable, fast DNS server like Cloudflare (1.1.1.1) is manually assigned. This can sometimes improve the “slow upstream media” issue.
Gaming routers like the TP-Link AC5400 sometimes have built-in Quality of Service (QoS) or other traffic management features designed to prioritize game latency. In some cases, these features can interfere with Roon’s real-time, low-latency RAAT protocol. If the above steps don’t work, you may need to look for and temporarily disable any QoS, traffic shaping, or firewalls within the router that might be throttling or mismanaging the data flow between your iMac (Roon Core) and the Lumin (Endpoint).
Please try these steps, and let us know how it goes.
Don’t worry, we’re only asking you to downsample temporarily as a test. We need to see how the system responds when less data is in transport over the network.
Some of the suggestions mentioned in the post above refer to granular options and jargon within your router settings administration page. The gist of it is that your router might have some traffic management software that is hyperactive when it comes to managing Roon’s protocols. Often called “Quality of Service” (QoS), this functionality is much like a traffic cop, inspecting packets and delaying or prioritizing their passage across the network accordingly to optimize network performance. It can make things arrive out of order, from Roon’s perspective. Look for a setting called “QoS” and try disabling it.
As mentioned above, this usually points to an account subscription payment or credit card expiry. Since you said Lumin app playback of Qobuz has no issue:
Please check that you are using same Qobuz account e-mail address (not username) for both Roon and Lumin app. It is not rare for people to have multiple accounts and got them mixed up, and only one of them has valid payment.
Please use a web browser, log into Qobuz web site using the same Qobuz account used for Roon, and check your Qobuz subscription status, and payment history.
