Meridian 251 version 1.1
Description Of Issue
We use this as an office streamer running a radio station all day long. It will at random times just disconnect. Itnever seems to run more than an hour or so without a disconnection
Which radio station does the issue occur on - does it impact multiple radio stations or just one in particular?
If you try to leave another zone running on the same station, does the issue occur on the other zone at the same time as the issue occurs on the Meridian zone?
That sounds strange, maybe this is device related.
Yes, please try another zone as well. If you don’t have any easily accessible, you can try to connect the HDMI output from the Nucleus to a TV/AVR as a test and use the HDMI zone.
@noris This would appear to be a Nucleus issue. The 251 would not show up as an audio device,so I tried a second unit. It would not connect either. I disconnected from the Nucleus and used the PC as the server and it has worked flawlessly
That is very strange in that case. If you try to temporarily host the Roon Core on a PC, does the Meridian fail to show up there as well?
Open Roon on the other PC you wish to try as the Core
Roon Settings -> General
Disconnect
On the “Choose your Core” screen, press “Use this PC”
If asked to Unauthorize, you can go ahead and do so. You are limited to one active Roon Core at a time but you are free to switch between them as often as you’d like.
Verify if the same behavior occurs on the different PC
Thanks for checking this is strange in that case…
Do you see any devices in Roon Settings -> Audio when using the Nucleus Core?
Can you please share a screenshot of your Roon Settings -> Audio tab?
Is there any change in behavior if you try to toggle IGMP Snooping / Proxying settings on your network configuration? These settings have sometimes helped when there are discovery issues with multicast.
If you have a fully un-managed network, that would be an even better test.
Well that changing IGMP Snooping allowed the meridian to be found again. However we still have an issue that when using the Nucleus we lose radio and then even when we try a playlist of any type it looks to play but does not have audio . It can only be corrected by rebooting the Nucleus
Since the Meridian is the only device impacted and it was failing to show up previously as well, I suspect that having the managed network is causing some kind of interaction where multicast briefly stops working properly and the Meridian stops playback.
Can you try both Nucleus and Meridian on an unmanaged switch?
You can find our networking best practices guide here:
We don’t have anything specific for Meraki, but we have the following suggestions for Managed Switches:
Managed Switches
Managed switches can be very robust, but they are often designed for professional installation, so in many cases the out-of-box configuration is not right. If your switch has a “flow control” setting, please make sure that it is enabled. Also, make sure that the switch is not performing any sort of throttling that might impact communication between cores, storage, remotes, and/or audio endpoints. Finally, ensure that the switch is configured to pass multicast and broadcast traffic. If in doubt about any of this, try temporarily replacing your managed switch with a “dumb” switch to see if things improve.
