Audio devices not showing on home network (ref#3JB1AA)

Hi! What’s not quite right with Roon?

· None of the above quite fits

None of the above quite fits

· None of these quite match

Tell us what's going on

· My audio devices connected to my home network are not showing.

Tell us about your home network

· I have an Eero 7 mesh network, ATT fiber connected to their BGW620-700 gateway, Mac mini M4 pro, Tahoe 26.2

Hello @Gus_Psarros,

Thanks for reaching out — we’ll need a bit more detail to understand what’s happening here.

Could you please clarify the following:

1. Which audio devices are not showing up?

• Brand and model (e.g. streamer, DAC, AVR, speakers, etc.)
• Are all devices missing, or just one specific device?

2. How are those devices connected?

• Ethernet or Wi-Fi
• If Wi-Fi, are they connected directly to the Eero mesh or to the AT&T BGW620 gateway?

3. Where is Roon Server running?

• Confirming it’s on the Mac mini M4 Pro
• Is it connected via Ethernet or Wi-Fi?

4. Do the devices appear in Roon at all under Settings → Audio, or are they missing entirely?

Since you’re using an Eero mesh, please also check:

• That multicast / IGMP / mDNS is enabled on the mesh
• That there is no client isolation between wired and wireless devices
• That all devices are on the same LAN / subnet (no guest or isolated SSIDs)

Mesh systems can sometimes block or limit device discovery if multicast isn’t handled correctly.

Once we have these details, we can guide you more precisely.

Hi Vadim,

Answering your questions in order:

1. None of the devices are showing. I have the following devices:

• B&W Formation Speakers
• B&W Formation Wedge
• Lumn P10 streamer
• EverSolo streamer
• WiiM streamer
• Marantz receiver
• MacAir

2. Depending on the device, it is connected either by Ethernet or WiFi. All devices are connected to the Eero Mesh

3. Roon Server is running on my MacMini M4 Pro. It is connected via Ethernet. The WiFi is off. I tried to see if switching to WiFi would fix the issue, but it did not. Up until 7-10 days ago I did not have any issues.

4. All of the devices are missing entirely. The only Audio device that shows is the MacMini.

5. I do not see an option for multicast/IGMP/mDNS. Also, it appears all of my devices are on the same LAN/subnet, but I am not the most educated in this area.

Thanks for your help.

Hey @Gus_Psarros,

recent macOS updates have tighter (and more obfuscated) network security settings than preceding macOS versions.

Can you please navigate to macOS System Settings > Privacy & Security > Local Network, and make sure Roon and Roon Server are allowed.

If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.

Thank you!

Hi Benjamin, I followed your steps and it worked. However, when I went to restart all of the audio connections disappeared. This is not a viable, long term fix. What do you recommend?

Hi @Gus_Psarros,

See here:

macOS Sequoia Roon Server / Device Connectivity Issue, Roon Status & Workaround

The Issue macOS Sequoia (version 15), has tighter (and more obfuscated) network security settings than preceding macOS versions. This is causing problems during Roon updates; despite being previously enabled during the Roon installation MacOS, after an update MacOS is denying access to the network (yet retains displaying all is well). Roon Status Roon support and product team are aware and are working a fix, which I understand is quite involved (I have no timeline for that, sorry). The Workar…

Unfortunately, this is the only option for now. Our team is working on a long-term fix, and we’re also hopeful that Apple will address the issue on their end in the long term.

Ok, thank you for your help!
