Roon Multiroom Sync Issues (ref#TF0R1T)

Support

Thank you for the timestamps @Thorsten_Heinrich.

To confirm, you group the devices before playback starts, correct?

You have my apologies if this has been glazed over, but have you tested out using the Resync Delay function at all? If not, temporarily try enabling resync delay in Device Setup:

  • Device Setup > Resync Delay > try 500ms – 2000ms This gives both endpoints time to prepare before playback starts.

Another thought - If the Naims support multicast RAAT, Roon might default to unicast depending on network discovery. You can try toggling IGMP snooping off/on in your router’s settings to see if multicast behavior improves zone grouping.

Thank you! :pray:

Hello,

To confirm again. The two Naims have been grouped this way for years. Only the third Naim always plays alone.

Sometimes the group is out of sync from the start, sometimes the group is in sync at the beginning and loses during the game. Both possibilities exist.

Resync Delay > I know this function and have tried it in the past. There were no changes in the synchronization behavior. Nevertheless, I just set it to 1000ms.

IGMP Snooping > As far as I know, this is not possible (Fritzbox 5690 pro), but I’m no network expert! > “Disabling/enabling IGMP snooping in your router’s settings…”

Thank you!

Got it, thanks @Thorsten_Heinrich.

We don’t have immediate next steps just yet, but our team is actively reviewing your case. We’ll follow up with more information and troubleshooting guidance as soon as we have an update.

We appreciate your patience in the meantime! :raised_hands:

Hi @Thorsten_Heinrich,

Our development team has some additional follow-up questions for you:

  1. Does this happen with local tracks / TIDAL/Qobuz or just the radio?
  2. Outside of Roon, do the stations stay in sync?
  3. Does this happen when one zone is grouped with a non-Naim zone?
  4. Does this issue happen if all your devices are connected via Ethernet? Turn off WiFi if possible.
  5. Bypass any switches/mesh nodes and connect directly to your router - do the same issues occur?
  6. Does Roon Ready have clock master priority? Can you try to set a different priority?
  7. Try to disable sleep mode and see if the same issue occurs.
  8. Lastly, are you able to roll back and test on older Naim firmware? The issue seems to be discussed here: Multiroom Issue with Roon since Naim update - #60 by Bandi92 - Streaming Audio - Naim Audio - Community

Thank you! :folded_hands:

Hello,

Thank you very much.

I think we should close this request. We’re going around in circles, building castles in the air.
Some of the questions are repeated and have been answered multiple times; some are simply not possible.

I’ve been living with this for a long time; this is the second request, and I’ve already put a lot of effort into finding solutions. This isn’t support.

Thank you for your efforts.

Hi @Thorsten_Heinrich,
Of course, we’ll go ahead and close this thread for you.

We understand how frustrating this issue has been, and we truly appreciate your patience. As mentioned earlier, we’re actively working with Naim to find a solution. Once there’s meaningful progress, either Roon or Naim will share an update publicly.

Thanks again for bearing with us.
