UGameplayStatics::SetBaseSoundMix

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Sets the active base sound mix for the audio engine, applying the EQ and volume/pitch adjustments defined in the mix asset globally. Only one base mix can be active at a time.

Caveats & Gotchas

• Calling this replaces any previously set base mix immediately; there is no blend or fade transition unless the SoundMix asset has FadeIn time configured.
• Passing nullptr clears the current base mix and restores default audio settings.
• The base mix is separate from pushed sound mixes (PushSoundMixModifier); they stack on top of the base mix, so changing the base mix while modifiers are active can produce unexpected combined results.
