Too Many Failures on Roon Core. Zones work.

Describe your network setup

This is happening on the MacMini were my core resides.

What’s shown in the screenshot is what happens if I attempt to toggle Exclusive Mode on or off.
Restarting the core shows them as enabled again.

All DSP is off.

I had a similar problem when these same USB speakers were connect to my Core on Windows.
My Core is now on a Mac.
But in this case I can’t play via the built in Mac speakers either.

Hi @Placebophile, Thank you for your post. Diagnostics show the ORA Zone refusing to play PCM at 16-bit, 44.1KHz because of unsupported format errors. Can you please share a screenshot of the following?

Hello @Placebophile ,

Thanks for reaching otu. Does this issue happen only when using the ORA, or does it happen when using other USB audio devices as well? Do you have any VPNs or additional firewall apps that could be blocking Roon from communicating with the device after establishing Exclusive mode?

[Placebophile (Jeff)]

Hi Noris,
Appreciate the fast reply.

No luck trying other USB devices.
Trying to enable a new device would start the infinite enabling loop pictured above requiring a restart.
I tried 2 USB devices and the built in speakers with Exclusive mode on or off and Mac Audio output set to different outputs.
Same result - Too many failures, with both local music and Qobuz.

No VPNs or Firewalls.
MacOS 26.2
Networked zones work fine. This only happens on the Mac with Roon Server installed.
The USB devices and built in speakers all work with all other audio apps.

Just discovered something:
I have Roon Server on my Mac mini.
This issue only happens if the Roon App is open on my MacBook Air.
If I close the Roon app on the MacBook Air playback on the MacMini works as expected.

At one time my Roon Server was on the MacBook Air.
After I moved it to the MacMini I uninstalled Roon from the MacBook Air and (I thought) manually removed all traces of Roon and reinstalled.

Very interesting @Placebophile - I’ve just followed up via PM with some advanced troubleshooting steps that should help you.

Let me know how it goes and if you run into the same issue afterward. Thank you!
