Frequent RAAT dropouts dropouts/stops with Devialet via Ethernet

Sorry, indeed on a 200 it’s still Air.
I’ll not upgrade the Devialet hardware until yours works fine then.
Btw, is yours a former 200?

AIR still works perfectly on until new ones, so upgrade or not on your own schedule.

Mine was a new 440.

Same problem here (as is also described in a couple other threads). Today I installed RoonServer on a Win 10 i7 laptop and moved it to plug directly into the router (circumventing my whole house structured wiring). Problem still exists… dropouts and the “Audio file is loading slowly…” error.

I’m hoping @support will chime in soon to let us know if it’s a bug or a networking issue on our part. AIR works fine as does playback to other RAAT devices like the microRendu.

Any progress on this bug? Anything you need from us to help investigate?

Hi everyone,

Our team is hard at work investigating these reports. We will be sure to keep you updated here as soon as we have more information. We appreciate your patience and feedback as we are looking into this.

A post was merged into an existing topic: Audio file loading slowly since Devialet RAAT


after the latest update my Expert 1000 sounds very good with roon but I have dropouts when the file is high resolution (bigger 48kHz). On teh Devialet I have Version 2.2.4 RAAT SDK Version 1.1.33. In roon software the Expert is marked with “not certified”. I run Roon on Windows 10 and my data is on NAS. Iverything works fine with my PSAudio Bridge 2 in my office with same cor and NAS.
What can I do?

Thanks Rainer

Hello Support
I am using the latest Roon Version on a 64 Bit Windows 10 i7 Lenovo T440s laptop with SSD drive for ROON . The laptop is connected via Ethernet to a ASUS RT AC3200 router.

I have a Devialet Expert Pro 440 CI with the latest Roon RAAT firmware. Since updated the firmware, the new Roon RAAT zone keeps losing signal (dropout) and pauses for a while then continue playing, or, jumps to the next track. I am also getting something like “network performance slow” message. I can still use built in Roon Devialet Air without a problem with both standard and High Res music. The Devialet amp (Master) is connected using direct Ethernet connection via the ASUS router.

I see there are similar issues reported. I have reported to Devialet and they also suggested I should report this to Roon as well. Hope you can help? I would attach a log file but not sure if this facility is available via this interface…@Support

Kind regards

@support It would be really helpful if you would just let us (Devialet users) know that you have seen that there is a problem with the Devialet Roon Ready streaming and that you are looking at the problem as the current silence is very Devialet like.

What has Devialet said about the issue?

I have sent a message to Devialet’s support but they haven’t replied anything yet…

What would they be expected to say? If you use AIR the streaming works perfectly , if you use Roon Ready it doesn’t and you get failure to load, and quiet patches in songs. Unless I have misunderstood Danny’s message at the start of the Roon Ready Cerification for Devialet posts then it is not released until Roon are 100% satisfied that it works correctly.

Which it does not. SO from my viewpoint this is a Roon problem.

Also so this one from 3 posts down in that thread

And he is right - it does :sunglasses:

Where are the posts from the 1000s of other users using RAAT devices? RAAT is a standard protocol, they shouldn’t be doing anything special on the server side just for Devialet. There is something wonky with Devialet’s network implementation in my opinion, not necessarily RAAT.

I would have hoped that Roon’s certification process would have been intensive or covered enough network topologies to reveal it as it obviously affects many Devialet users.

Seems strange that my Logitech Transporter (over 15 years old design) and a $35 Rpi don’t have any issue,not so with the $$$ Devialet?

Those devices can expect only one protocol at a time I do believe. The Devialet has the ability to detect Devialet Air, Airplay, RAAT, UPNP etc automatically on it’s network interface correct? Is it possible turn the other features off completely and only have the Devialet expect RAAT? Does this help?

Of course my Rpi doesn’t support Devialet Air, but I can use it with RAAT and Airplay in Roon and I can use it with UPNP with other software. All this with free Linux distroes, not impressed with Devialet and network audio.

I understand the Pi can do different modes, I have one. Mine was always configured in one mode only, RAAT.

I understand your frustration, I went through it as well, I’m trying to help troubleshoot if the issue is related to Devialet’s detection of multiple streaming protocols.

I’ve been having the same problems with RAAT to my Devialet as reported here and in several other threads. I’m quite surprised we haven’t seen any response from Roon although I suspect it is an issue with Devialet’s latest firmware. Still, Roon’s QA should have caught this.

For what it’s worth, RAAT works great on my two other (non-Devialet) endpoints and AIR works fine to my Devialet. It is only an issue with RAAT to my Devialet… Frequent dropouts and occasional “Audio file loading slowly…” error in Roon.

Hoping Roon @support will at least acknowledge the problem and indicate that they (or Devialet) are working on it.

Since there is so many Devialet owners with this issue, I expect Roon to give us a feedback on this. Hopefully it can be fixed with a small sw update, either from Roon or Devialet. There is no buffer to increase with RAAT, so I don’t know what more to do.
