Mac mini not remembering HomePod mini stereo pair output setting after restart

Hi,

macOS does not natively treat AirPlay-based stereo pairs as permanent, persistent sound hardware across a hard system restart, often reverting back to the Mac mini's built-in or default physical audio device. [1]

Why This Happens

• AirPlay Protocol Limitation: macOS treats stereo-paired HomePod minis as network AirPlay targets rather than directly attached wired or core audio peripherals.
• State Loss on Reboot: When the Mac mini restarts, the system audio preference initialization loads local hardware first before network-based AirPlay endpoints fully handshake, causing the Mac to drop the stereo AirPlay route and default back to internal or fallback options.

Workarounds and Fixes

• Manual Re-selection: Use the Control Center via the menu bar after every reboot to re-route system audio to the HomePod mini pair.
• Audio MIDI Setup (Aggregate Device): Open Audio MIDI Setup via Spotlight, create an Aggregate Device including the individual HomePod AirPlay streams, and select that aggregate as your system output. Note that this requires keeping the Apple Music app open in the background and may introduce minor latency.
• Accept Temporary Behavior: Real-world user consensus on community forums indicates that relying on a physical USB or wired connection is far more stable if you require a zero-maintenance default output that survives a hard restart

For info, please read the comments, some users are experiencing the same problems.

I think you need a 6e wifi compatible router for HomePods and Mac to have a permanent connection.

Ok, so what does it means exactly this Apple note about software version 27.2:

“HomePod speakers with your Mac lets you set HomePod as the audio output for everything you do on your Mac, with a responsive and persistent AirPlay connection.”

I’m a little bit confused by this ‘new development’

About Software Updates for HomePod - Apple Support

Yes, thank you so much for the advice; the router is Wi-Fi 7 compatible, other devices in the home have been working properly for some time and all the required conditions are met (Mac mini M6 macOS 27.2, HomePod mini 2 , in a stereo configuration). Is no one else experiencing any problems?

Hi,

If both Notes and Music are crashing on your Mac mini, I recommend trying these steps:

Restart your Mac.

Go to System Settings > General > Software Update and check for available updates.

Try opening Notes and Music again.

Start your Mac in Safe Mode and check whether the same problem occurs.

If the issue started after installing any third-party extensions or utilities, check their compatibility with your macOS version.

Could you share your Mac mini model, macOS version, and whether the apps crash immediately or after opening specific files?

This will help narrow down the cause.

Thanks for your reply.

Actually, it’s not a case of the Notes or Music apps crashing (I don’t think I mentioned them); the issue is that the default audio output—selected under System Settings > Sound > Output—isn’t being saved.

It resets every time the Mac mini (M6, macOS 27.2) restarts or goes into standby, even though it’s set to use the HomePod mini 2 (OS 27.2). I hope that clarifies things.

Not sure. It’s all very new. I have an M1 and original HomePods mini’s, so can’t test it.
