Audio for PVP.Net Client

I just thought this would be a good feature to add to the client. I honestly dislike the sounds the league client gives off normally. The music, the sound effects. Its more so that I like doing other things on my computer that requires audio, and thus my suggestion is this: the client should offer a feature to just turn the sound on for notifications such as game invites, the accept/decline screen, and private messages. I have been wanting this since beta and I thought it would become and option by now but it hasn't so I thought I would put my word out.
