BBC stations breaking up requiring coreaudiod force quit

Hi @GraemeM,

Thanks for letting me know those timestamps. I have gone ahead and enabled diagnostics mode for your account and what this action does is a set of logs will automatically be uploaded to our servers for analysis.

I’m looking over the log report now and I’m noticing something strange - it appears you’re also losing connection to our metadata servers around the same time the BBC stream drops off, and the stream looks like it was buffered.

Can you provide a full overview of your network including the model/manufacturer of your router and switches? I believe this could be related to how you have the network configured.

The router is a Synology RT2600ac > TP-Link TL-SG116 switch > TP-Link TL-SG1005D switch > mac.

The first switch uses green ethernet, another thread from a Mac user said he had found green ethernet to be the cause of dropouts.

Hi @GraemeM,

I would try to temporarily bypass both switches and have the Mac connected to the router as a test.
As Ged mentioned, the first switch is an EEE switch, and there have been other reports of EEE switches having issues working nicely with Roon, so we should eliminate this variable.

Thank you. You try to save the planet and accidentally ruin something else. I’ve bypassed the eco switch so we’ll see.

A post was split to a new topic: Frequent stops on BBC Radio

No radio drop outs since bypassing the Green switch to this point.

Jack - that sounds like the same problem I had before bypassing the switch.


That’s fantastic news @GraemeM, it does sound like the switch was the problematic component so glad to hear the system is stable since bypassing the switch!

The topic I started is closed so can’t add to it so will continue here. The radio stops reared their ugly heads again. Restarting the router (Synology RT2600ac) fixes the problem for a while. I’m wondering if there is a setting in there that could be causing a problem?

Hello @GraemeM. I’m sorry to hear your problem has returned. I’ve re-opened the topic for you, moved the post here and @noris will be back to help in due course.

Hi @GraemeM,

Sorry to hear that the issues are back and thanks @BrianW for flagging me down! @GraemeM - If you try to bypass all of your switches and have the Core connected to the router, do you still see the same behavior?

Last time I checked logs, there were signs of more general networking issues and this would be a good test to simplify the setup and verify where exactly the system is encountering issues.

I’ve done some more testing. Removing all switches makes no difference.

Strange thing is if I reboot the router when the stopping problem occurs it will be fine for a day or so. The router is scheduled to reboot every day at 5 am anyway but that does not seem to prevent the problem occurring.

Same radio stations are fine played in Auralic Lightning DS app and Naim app and by airplay to the Auralic. It is just Roon that has a problem. At it’s worst radio seems to stop every 5 minutes. Do you have a process that runs every 5 minutes?

Today I noted stops at 6:58 approx, 7:11, 7:43, 14:22, 14;50, 15:42. 15:48?, 16:00?

Hi @GraemeM,

That’s interesting to note, it sounds like the router itself is dropping out in that case. Do you have the latest firmware install on your router?

What happens if you try to up-sample all of your content to one sample rate, does the issue still occur?

Latest firmware installed on router.

Upsampling made no difference.

One other thing I’ve noticed while having the Zones tab open when the stops occur is that all active zones stop and most zones in the list disappear and reappear within a second or two. While it is doing this the cursor sometimes turns to a spinning coloured ball if over the Roon window. If another zone is playing a locally stored or streamed album it will also usually stop but not always.

Hi @GraemeM,

Thanks for those additional details.

This sounds like the router itself is dropping these connections or you have a multicast issue going on.

Do you by any chance have IGMP Snooping or IGMP Proxying setting on the router you can try to toggle?

In case it is the router itself, do you have another one around the house you an try to temporarily use in place of the current one?

Router has IGMP settings. It has “IGMP querier timer” which is set to 260 seconds which is not far off 5 minutes which is the time interval between radio stops when it is at it’s worst. IGMP snooping is enable, proxy is disabled.

Hi @GraemeM,

Try this, have a ping test running in the background (to Google or a big provider) and see if you are getting packet loss when the issue occurs:

Been monitoring ping. There is no packet loss or slow ping associated with the radio stops.
