[GAMEPLAY] Super Galaxy Rumble Intro Sound Worked on Old SR, not on New SR

I used to be praised for my amazing Super Galaxy Rumble introduction noise as his suit boots up for the first time! It used to make a nice noise when the game started, but now with the introduction of the new spawning pool where champions fade in slowly around 7 seconds or so, the sound seems to be either muted or cut off entirely though you might hear a little of it.

Seems to happen 10/10 times.

REPRO:

1. Queue for a ranked (maybe normal) game on Summoner's Rift.
2. Select rumble in champion select
3. Select Super Galaxy Rumble skin.
4. Observe sound effect DOES NOT PLAY as it used to on loading into Summoner's Rift. Usually it starts to play and then gets cut off after .25 seconds.

EXPECTED: Rumble's intro animation and sound effect occurs the moment he appears visually, not the moment the game starts.
