SFX Audio control

Hello world,

I just started to tinker with audio this morning.

I have 2 volume settings : BGM and SFX

BGM (Background music) :

Player Source: Audio component present and controlled by the base HUD Blueprint

File Sound Class: Engine:Music.

SFX (Sound FX):

Player Source: Global Audio channel.

File Sound Class: Engine:Master

SFX audio files are sometimes played through animations but more often using:

Simple Basic stuff…

I am aware that i can explicitly fetch and use the “SFX Volume” in respective blueprints while i play new sounds.
However, i was hoping that there might be an alternate & more efficient method to do so. Something that sets the global volume for every other sound played during runtime.

Not that im lazy to update all the blueprints. Just that, i would like to minimize the “variable fetch and use” operations.
I wouldn’t mind reworking on the entire audio system if i have to as long as the code is efficient.

Using the SFX variable value while playing sounds works, but not for Animation notifiers. In short, that approach is useless.

Here is what is needed…

1: Create new SoundMix and set sound class to “engine-SFX”.

2: Project settings → Audio: Set default sound mix and class.

3: World settings → Audio: Set sound mix. (not necessary).

4: Edit all audio wav and cue files (apart from BGM) to SFX class (Bulk edit via property matrix is useful).

5: Configure volume controls.

**Done **
