NAD/Bluesound Grouped Zones out of sync, stopping playing, and/or skipping tracks [Investigating]

Support
109

I had a quite long mail thread with a representative from Bluesound on mail, and she confirmed that she had reported the issue (I gave a lot of context) to their dev team to look at after some mails forth and back. Haven’t heard back yet, but I try keep the hope up… For now all my 12 zones in the house (3x NAD CI580v2) I can basically not use Roon :frowning:… The only thing that work sis grouping up groups in BlueOS and then play towards them in Roon. Can’t group them with any other devices or zones in Roon though, because then the inconsistencies arise.

It’s quite clear Bluesound don’t put a high focus on maintaining the Roon stability… it seems they ignore working on it as they “already got the certification” and I wonder how Roon can tolerate that… they should remove the certification…

Hello there
Following the thread here, I requested NAD an older firmware of my device
Here the réponse I got:

Thank you for contacting The NAD Electronics Support Crew.

Based on the information you have provided, the issue you are experiencing appears to be related specifically to ROON. It may be best to reach out to ROON directly at ROONLabs.com

For more information about our partnership with ROON, please see: Title of Page. They are a great partner and I am sure will be happy to assist further.

Thank you for choosing NAD Electronics, HEART+SOUL You Can Hear.

Any idea where I can find older version?

Thanks

Don’t know what your device is but maybe look here

GitHub maybe? Google search?

First timer here in this thread… though I’ve been having the same problem described in this issue for months. I’ve received various BluOS updates over that time and none of them have fixed it.

My BlueOS devices are (as of 2023-12):

Device Version
Bluesound Node 2i BluOS 4.2.0
Bluesound Pulse Flex 2i BluOS 4.2.0
Monitor Audio IMS-4 * BluOS 4.2.0
NAD T-778 BluOS 4.2.0, MCU 2.24

* (essentially a rebranded NAD CI 580), it has 4 channels

All devices are hardwired over a 1GbE network with DHCP reservations, all devices are on the same subnet.

Roon Setup

  • ROCK on an Intel NUC running 10.9.6.23
  • Roon Server version 2.0 (build 1353)
  • Roon Controllers (many, both ios and android, but all up to date)

Issues include:

  • Out of sync playback
  • An output device sometimes just goes missing like this:
    roon-unavail
    roon-unavail924×814 32.9 KB
    • Logs show (the Pulse Flex is “Kids Room” in the screenshot ):

    • There is no networking reason for it to fail the connection. The device is on the same subnet as roon, the device responds to pings, and the BluOS controller app can play it just fine.

I would like to see some definitive response from Roon about what is going on here. Please throw us a bone… are you looking into this? Do you even care?

I don’t care if the result is Bluesound loses their certification, I’ll sell my BlueOS devices and get other properly Roon ready onces.

113

Its very frustrating… neither Bluesound nor Roon seem to care, even though Bluesound clearly marker their devices as Roon Ready.

I dont get why it is like this :sob:

I might try to refund my NAD CI580v2s but now lots of time has passed so we will so how that goes… :confounded:

114

I have exactly the same issues as you describe .

115

Hi all,

Just wanted to chime in here and say that I have exactly the same issues, Bluesound speakers go out of sync when they are grouped in Roon (but no issues when using the BluOS app). This is super annoying and basically means that I have stopped using Roon for multi-room listening, which is the reason I got it in the first place. It needs to be fixed ASAP!

Many thanks.

Joining this thread, as I’ve been experiencing the same issues as everyone else with 2 Bluesound Nodes and a NAD CI-580v2 (zones going out of sync, playback slowing down/speeding up, skipping tracks).

My devices all updated to BluOS 4.2.6 yesterday, and thus far I haven’t noticed any sync problems in the last 24 hours (fingers crossed). Until now I hadn’t been able to play more than a few tracks without the issues cropping up, and had resorted to running them all through Airplay. I’ve tried several different grouping configurations (including with non-BlueOS Roon endpoints), and so far so good. Wondering if anyone else has noticed improvement with the latest firmware update. Hoping this isn’t just a mirage.

117

I too am experiencing better syncing after the update. I haven’t tested it for more than a couple hours so far, though.

118

So far so good. I hope this is the solution we’ve been waiting for.

No joy for me, still exactly the same sync issues after update. I’ll keep exploring, unless anyone has any other ideas…

Description of Issue

After a reboot of the BlueSound Node 2i the music in sync with the DCS Network Bridge.
One system is in the kitchen, the other in the living room. Both systems are close enough, so the slightest difference can be heard.
After a while (an hour maybe?) one of the systems is ahead and the difference keeps on growing.
It seems this issue started after the last firmware V4 upgrade of the Bluesound Node 2i.
Can you help?

121

I decided to update two days ago despite limited feedback at that point, figuring it was unlikely to be worse.

So far my system seems to be running much better with no sync issues observed yet.

Unfortunate to hear it doesn’t seem to be working for everyone, and disappointing that the user community is left to figure this out with no communication from Bluesound or Roon. The release notes made no mention of Roon, so we are basically left guessing……

122

Jikes, my topic was moved here. Did not realize it has been such a big topic in the community.

I read trough this and just tried selecting Roon Ready via the BluOS app. See if that helps.

Multi-zone play between Node 2i and DCS Network Bridge is the main function of Roon for me.

123

Selecting Roon in the bluos app seems to do the trick. If not in sync just selecting something else and go back to Roon does also work.

Would still prefer for this just to work without hassle

124

Roon @support could we please have an update? Is Roon working on it? Is Bluesound? Multi-device play is a key function of Roon for many of us. We used to be able to sync devices reliably. Has there been progress on identifying the cause of this issue and a solution?

Bumping/highlighting this. I am still experiencing this problem every day, and it is hella annoying. I need to know this is being looked into, otherwise Roon really isn’t worth the money for me and I’ll say goodbye. Thanks.

Did you update to the latest BlueOS (4.2.6) and newest Roon?

I did just realize that it seems that my setup is actually playing in sync… (Devialet Phantoms and NAD CI580v2) This has never happened since last summer… so something has definitely happened.

127

I’m on the latest versions and still experience the problem.
Each time I have to open the BluOS app, go to some radio station, switch back to Roon and only then it plays in sync.

128

I think action of invoking a function in BuOS is results in synching the players. I my case I just stop and start play in BluOS for the Roon Ready units and synch is restored. Since both Roon and BluOS are black boxes it’s tempting to develop theories about why it works when we intervene.
