Zed autos and shadows don't make noise anymore?

So I haven't played Zed for about a week or so and when i was in game with him, i found that his auto attacks and most of his shadows, his jokes, and the pop on his death mark (so basically his everything) don't make noise right now. I thought maybe it was just a bug with the shockblade zed skin, but when i went into a game with the classic skin on, he doesn't make any noise at all, no matter what he does. Is anyone else having this problem, where Zed isn't making noise no matter what he does, or what's going on??
