Soldiers Death Sound Ending Prematurly

so i was playing my first game as Azir on PBE today and as i was playing i found i was having real trouble predicting when his soldiers would die and it wasn't because i didn't have any sort of feeling on how long they lasted I've played many games with and against him. but then i noticed it was the sound of his soldiers it sounded like it was ending half way through the death and wasn't quite getting to a part were it sounded like they had dispersed in the wind it wasn't getting to a low enough pitch and was getting cut off half way through. unfortunately i don't know the first thing about making SFX so i can't make a sound clip of it doing just that. but if you can please post that i would highly appreciate it.
