UGameplayStatics::ClearSoundMixModifiers

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Immediately removes all active Sound Mix Modifiers from the audio system regardless of their push counts. Useful as a failsafe reset, such as after a level transition.

Caveats & Gotchas

• This is a nuclear option — it resets ALL mixes, including ones managed by other systems or Audio Volumes. Do not call it unless you own the entire audio mix state.
• The deactivation is instant with no fade; sounds currently affected will snap to their base levels and may produce audible pops.
