Address Naim multi-room drift with RAAT

Feedback Feature Suggestions
1

Multiple users have seen issues where when 2 or more Naim devices are in the same Roon multi-room group, the sound synchronization between the devices drifts over time. See this thread in the Roon forums for more details.
All reports, so far, have the Muso 2 as part of the setup, so that may be the root cause.

This problem is RAAT specific as two of the 3 reports (as of 1/6/2025) indicate that using the Focal/Naim multi-room functionality does not have this issue.

Thanks Bjorn for raising. I’d hope someone from Roon takes ownership to zoom in and get sorted. As end-user it’s frustrating if you invest in Roon Ready equipment which then disappears when either of the parties update their software and leaves us empty handed…

TL;DR, this appears to be a Naim, not a Roon issue. More troubleshooting has happened by the community since I posted this. It appears to be isolated to specific Naim gear. The MuSo2 does not appear to be the culprit. Instead, the current hypothesis is that the high-end Naim streamers are the root cause. There was a recent update to those pushed out which may be the issue.

Oh, but I have the issue with MuSo2 + MuSo2 QB and Roon, which worked fine in past, but not since end of last year somewhere Oct-Dec started. So this would not align with current hypothesis I guess…

Good to know! That does invalidate the Naim only root cause. Back to Roon to work with Naim to get to the bottom of this.

Agree this got introduced just before Christmas. In my setup of NDX2, Nova and Kef LSX II it is the Nova that drifts.

The Nova also suffers from not responding to the Room stream request after it’s been on for a few weeks. Power off and on resolves.

My money would be on a Naim bug but IIRC there was a Room update a week or so earlier so it could be a mix of issues.

@Zebedee : My MuSo 2 has the same behavior as your Nova: It loses it ability to respond to Roon stream requests after a few weeks on.

Thanks for sharing. If you haven’t already, could you report to Naim please via support@naimaudio.com. They claimed no one else had reported the issue in my last exchange with them!

I will do the same. I have just bought two musos and a used NDX5 X2 to use the multiroom function so you can imagine how disappointed I am

Please could you tell me the subject of the post as I cannot find it on the Naim forum. Thanks.

Thanks for the link

Hi, Naim are saying this is a roon issue and they would have had more complaints if it were Naim. As the issue only occurs with multiple Naims via RAAT, let’s turn it around:

Are there users:

  • with multiple Naim MuSo 2 on latest firmware
  • playing via Roon RAAT
  • NOT having a sync issue

Thanks

Naim have picked up on the issue. Hopefully can reproduce and resolve.

I have had a response from Naim who say it is a Roon issue. Naim say that they have been waiting for a week for a reply from Roon.

I have received a message on Naim’s forum saying that they are now talking to Roon’s CTO to address the issue. Very promising
