if you are working in C++, you can use

SoundClassObject->Properties.Volume = NewVolumeFloat;

if you want a blueprint solution, Rama has some useful sound blueprint nodes in his VictoryPlugin. inside VictoryBPFunctionLibrary you can find VictorySoundVolumeChange and VictoryGetSoundVolume.

you can download his plugin here:
