Quick Answer
Aura Sync usually stops working because an ASUS background service stalled, a component is outdated, or another RGB app is fighting for control. Restart the ASUS services first. If that fails, update Armoury Crate and its modules, remove conflicting RGB software, and as a last resort do a clean reinstall. Most cases are fixed without touching hardware.
Why Aura Sync Stops Working
Aura Sync depends on several ASUS services and drivers running correctly in the background. When one stalls, usually after a Windows update, sleep, or restart, lighting control breaks. Other common causes: outdated Armoury Crate modules, corrupted lighting profiles, a damaged ASUS System Control Interface driver, or a competing RGB app like iCUE, MSI Mystic Light, or Razer Synapse overriding Armoury Crate. Identifying which one applies determines the fix.
Fix 1: Restart the ASUS Services
Press Windows + R, type services.msc, and restart LightingService, Armoury Crate Service, and ASUS System Control Interface. Then open Armoury Crate and check whether your devices reappear. This resolves most temporary failures, since services often fail to load cleanly at startup.
Fix 2: Update Armoury Crate and Its Modules
Updating only the main app is not always enough. Open Armoury Crate, go to Settings, then Update Center, and install every pending update, including Aura Sync components and device SDKs. Outdated modules are a major cause of sync failures. If the in-app updater stalls, download the latest installer and run it over the existing installation.
Fix 3: Remove Conflicting RGB Software
Two RGB control apps cannot drive the same hardware. If you have iCUE, Mystic Light, Synapse, or similar software installed, uninstall the ones you do not actively use, or at least disable their SDK plugins and background services. Then restart the ASUS services from Fix 1. Conflicts like this are the most common reason only some devices sync while others do not.
Fix 4: Reinstall the System Control Interface
The ASUS System Control Interface is the driver connecting Armoury Crate to your hardware. If devices vanished from Aura Sync entirely, this driver is likely corrupted. Download it fresh from your device’s ASUS support page, install it, and restart. If problems persist after that, do a full clean reinstall: remove Armoury Crate with the official Uninstall Tool, restart, and install the latest version.
If Aura Sync Breaks After Every Restart
This usually means services are not loading at boot. Windows Fast Startup is a frequent culprit, since it skips full driver initialization. Disable Fast Startup in Control Panel, then Power Options, then Choose what the power buttons do. Also confirm the ASUS services from Fix 1 are set to Automatic rather than Manual in services.msc.
FAQs
Can Aura Sync stop working after a Windows update?
Yes, this is one of the most common triggers. Updates can stall ASUS services or replace drivers. Restarting the services usually fixes it without a reinstall.
Do BIOS updates affect Aura Sync?
They can, if the update changes how RGB hardware is exposed. If Aura Sync broke right after a BIOS update, check for a matching Armoury Crate update, since ASUS usually ships compatibility fixes together.
Can Aura Sync work without Armoury Crate installed?
No. Aura Sync is part of Armoury Crate and needs its services running. Third-party RGB tools can control some ASUS hardware independently, but not through Aura Sync itself.
Why does only one device sync while others do not?
Almost always a software conflict or a partially failed update. Remove competing RGB apps, update all Armoury Crate modules, and reset your lighting profiles to defaults.
Is Aura Creator required for Aura Sync?
No. Aura Creator is for designing custom effects. Basic syncing works directly in Armoury Crate without it.
