Roon slow loading and playback issues with Qobuz on B&W Wedge and Cambridge EVO150 (ref#RHCEI2)

Dear Daniel, I am still experiencing the same issues; Any further constructive feedback to try to resolve? If not, is there a way to cancel and refund my ROON subscription ? It is more a cause of frustration rather than a source of joy? thanks in advance !

Your iPad shouldn’t need QOS priority, it only controls your Rock. If speed tests indicate that the max download you get is 30mbps, set your QOS max to 25-28 not the full 30.

You indicate that you have no other internet options, have you looked into Starlink?

Thanks for that feedback. I have now changed to only the ROCK to be on QoS high and to 25 instead of 30 Mbs. Starlink is out of the question. I am not sponsoring Starlink in anyway, let alone the even more cost ! Qobuz + ROON + special internet provider. That is total overkill

Just one more note:

ADSL is really only capable of 24/2.
Bonded ADSL can get you 50/10.
VDSL is capable of 100mbps.

If your provider is selling you 100mbps, you should contact them and see why you are only getting 30.

The reason you set your QOS less than the maximum is to alleviate buffer bloat. Use this test site with QOS disabled and then also enabled and see how your internet scores.

I already contacted the Provider and they checked and the absolute maximum is 30 Mbps, they say they will change to fiber in the future. For the moment. The maximum is really 30 MBs. I contacted them because they announce '100 Mbps , but they checked this specific connection and it is really 30 mbps. Thanks for that test site and helping thinking along, which I really appreciated ! now changed tto 25 Mbps and only ROCK in QoS high. Let’s see!

If the QOS max change helps, you can then try slowly pushing up from that 25 until it gives you issues and then use the last value that didn’t give you issues.

Describe the issue

Continous problem with delays, slow start, disconnects

Describe your network setup

Already shared before: ADSL -> Router -> Wifi MESH network -> hardwire (ROON NUC): Laptop or iPad as controller, EVO150 Roon end point via Wifi

Additional for Support: I keep on having problems with

  1. EVO150 not starting based on start trigger from laptop (pushing start button, nothing happens for 2 minutes)
  2. DIsconnects in music while streaming
  3. You never seen when you click on the PLAY button so only after a minute you see a message ‘starting to play’
  4. Some songs just skipped yesterday and didn’t play at
  5. When playing exactly the same song directly via QOBUZ it works flowlessly, fast, no hick ups.

It is getting more & more frustrating and it feels like I am paying a subscription for something which doesn’t work properly and cannot get resolved for months.
It was working fine till October / November 2024 but something has changed in the ROON Software which makes it non functional anymore. I can stream netflix in 4K, I can stream Qobuz without any issues, I can stream 4K Video via my TV in Amazon, Disney Plus etc. But a relatively ‘simple’ music stream via the ROON NUC is totally unstable. I already spent 300 EUro extra on a Wifi Mesh network with QoS which is configured for the NUC & Controllers as ‘Important’ and no resolution.

What is wrong in my ROON NUC configuration which is causing this? Does a ROON NUC ONLY works with a fiber network of 100’s of MBs of downstream in order to a have bit ‘normal’ user experience, where QOBUZ , EVO150 itself, etc all seems to be more than happy to play.

ROON is nice for the lyrics & the lins, but the user experience (speed) is extremey worse compared to last year.

Just curious if other people are experiencing the same lately?

Thanks in advance for any additiona configuration/advice?

Start by removing all wifi in your setup. Even of you can stream 4K etc. Your network couldn’t be stable enough for the use of Roon.

What a strange comment: if the network is stable enough for Qobuz, for 4K streaming, etc, why wouldn’t it be stable enough for ROON? If that is the case, the whole implementation of ROON is a very very very poor one ! How can you even say ‘remove all Wifi’ from your setup? how do you connect your iPad hardwired to your network? As indicated: my ROON server is already connected hardwired to the Router, and as said: I am sorry, I cannot connect my iPad hardware to my router !

What a strange reply. Did you even read the page I linked to ?
I know as you mentioned that you can’t use your remotes wired but your server and endpoints normally can.
So I Will leave you in the good hands of the support team for further assistance.

My Server is and my end point can’t because I don’t have an ethernet available at that spot. And the end point works absolutely fine with QOBUZ direct, etc. So the fault is the ROON server. That constant advice of ‘make it hardwired’ just doesn’t work for everybody. If it is that complicated to get it working reliable it shouldn’t be sold “as-is” but only to be installed by professionals. My 2 cent.

And yes, I did read that article already multiple times. it is just a flawed approach this ROON approach. the server needs to download and transport it again to your endpoint. Anyway… it is what it s !

I see you had already had opend a topic, wich isn’t closed yet, where Roon support did some diagnostics of your network. So let’s wait for further anwers there.

Correct. This has been going one for a couple of weeks now. And it is getting frustrating. Indeed let’s wait for the Roon Support to see if they have anything else as a recommendation

BUFFERING

In order for Roon to group like zones it minimizes any buffering of the stream.Qobuz and Netflix dont so its not comparable.

Is the Server to Router connection ethernet ?

Wi Fi is almost cerainly the cause , hate say it but CA wi fi has issues, i had a CXN which simply wouldn’t work on WiFi, replace with
ethernet and no further issues

Can you try a temp ethernet cable between the router and the Evo ? Even as a test

The other try is a wi fi extender .with an ethernet port to act as a big aerial?

If you search the forum you will see endless posts wit your symptoms

Server to Router is ethernet. I will see If I can make a temporarily connection to my EVO 150. very unlilkey that is the cause as Qobuz & TIDAL (before) performed absolutly fine also with high res. But I will see if i can order a temporarily long network cable to check.

Did you miss the part about buffering Tidal, Netflix, Qobuz etc all buffer the stream quite heavily to avoid dropouts so even at hi res their native apps do not skip. Roon’s design cannot do that.

There are so many things that interfere with WiFi that’s its a bit hit and miss. Roon definitely behaves better with end points on ethernet

Roon is heavier on the network than Qobuz direct, and more sensitive to latency than video codecs that dynamically degrade quality and have large buffers, so a network that just about works with other protocols can fail with Roon.

Hi @Geert_Diels,

While we appreciate your continued details, we kindly ask that you keep your issue tied to a single thread. Creating multiple makes it more difficult for use to track. Thanks for your cooperation here!

Unfortunately, based on your Roon Server diagnostic report, it does seem to be network bandwidth related. Here’s an example of a poor connection trace :

Warn: [143] FTMSI-B-OE qo/969DE001: poor connection kbps:117.0 (min:1703.0)

FTMSI-B-OE refers to Roon’s internal File Transfer and Media Streaming Infrastructure (FTMS), which handles data transfer for audio playback, including buffering and streaming from local or online sources.

1703.0 kbps is the minimum bandwidth required for stable playback (this varies depending on the audio format and bitrate). 117.0 kbps is the actual bandwidth Roon is measuring for this stream.

Unfortunately, the connection is performing far below the expected threshold.

My apologies if this has been discussed already, but have you tested out using a different machine to host your Roon Server?
