Aurelion Sol Taunt and other VO bugs

Whenever Aurelion Sol taunts in a match the audio is completely silent, and on top of that some of his interactions don't properly trigger as well. I remember riot fixing this issue a while back however I think the problem resurfaced again for some of the voice lines. All of the special taunts are pretty much gone since the audio for his taunts don't work period. Other voice lines do not trigger either such as the ones when he gets shut down or when he enters the enemy base. Aurelion Sol has been my favorite character since day 1 and I really hope riot fixes this because his voice lines really bring out his character and make him such much more fun to play!
