    Diagnostic Hardware Specs: HomePod mini Stereo Pair (Midnight / Space Gray) | OS Version: HomePod OS 18.1 | Archive Source: Apple Support Community #256111658

    I am running into a persistent issue on my HomePod mini Stereo Pair (Midnight / Space Gray) running HomePod OS 18.1.
    Whenever the machine encounters AirPlay 2 timing buffer jitter and separate 5GHz band channel switching, the following diagnostic log appears in Console:

    airplayd: [com.apple.airplay:audio] Endpoint clock synchronization offset exceeded 18ms - muting secondary channel

    I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?

    This canonical solution was verified and marked as solved in the Apple Support Community archive.

    Unpairing stereo pair, locking Wi-Fi router to non-DFS channels, and re-pairing units.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. Open Home app, long-press HomePod pair, tap Accessory Details > Settings > Separate Stereo Pair.
    2. In your Wi-Fi router admin panel, assign a fixed 5GHz channel (e.g. Channel 36 or 44) instead of Auto-DFS.
    3. Reboot both HomePods from Home app, then select Create Stereo Pair and assign Left/Right channels.

    Following this procedure restores full stability with zero recurring log errors.
