When using PlayLocalSound on a particular sound object, i.e.:
game:GetService('SoundService'):PlayLocalSound(SoundInstance)
The sound will play using the Sound Objects own Properties (volume, pitch, etc) but won’t use any of the associated SoundEffects/Groups. This is unexpected behavior because I assumed that it would apply these effects, similarly to how the Preview in the Properties panel for the sound in Studio does use the SoundEffects.
I assume this is not intended behaviour.
