If AudioMatch doesn't seem to change your sound, work through this checklist. Most cases come down to a missing permission, the background engine being stopped by Android, or a Premium-only effect.
1. Is the engine running?
AudioMatch processes audio through a background service that shows a status notification. If you don't see it, the engine may be stopped — reopen AudioMatch (or toggle it on from the Quick Settings tile), and re-launch it if you'd force-closed it.
2. Are all permissions granted?
All setup permissions are required. Re-check Microphone, Notifications, Bluetooth and Now-playing access (notification access). Missing Notifications or Now-playing access is the most common reason the engine stops or presets don't switch.
3. Exclude AudioMatch from battery optimization
Android may shut down background apps to save power. Set AudioMatch to Don’t optimize: Settings › Battery › Battery optimization › AudioMatch (the path varies by phone brand).
4. A specific effect (Bass Boost, Reverb, Sound Stage, Limiter…) does nothing
Many effects are Premium features. You can still toggle them in the interface, but until you upgrade the engine bypasses them and shows a premium lock banner. The parametric EQ (up to 5 bands), TuneHub correction and the FAST personalization wizard all work on the free tier.
5. TuneHub picked the wrong device
If correction sounds wrong or absent, open the device card › TuneHub picker and confirm your exact model is selected and the correction is on. Tuning is saved per device, so make sure you're adjusting the headphones or speaker you're actually using.
6. It works in one app but not another
Some apps stream audio in a way that bypasses effects. Try enabling that app's high-quality/high-bitrate audio setting, restart playback, and confirm the engine is still running.
7. No sound at all, or distortion
- Silence — check your system volume isn't muted; in Advanced mode, make sure the High-Pass Filter cutoff and the Limiter/Attenuator aren't set to extremes.
- Crackling/distortion — soften any very large EQ peaks or cuts; on Bluetooth, try a different codec in Android's Bluetooth settings.
