Okay, as of recently (before the Cassiopeia patch) my sound worked perfect! No problems, never.

Now, I hear music, and some of the sound FX, but it's not centered with my screen as it used to be. I can be kog maw, spitting ooze at all the minions and not hear a thing.

Unless they're in the top right of my screen.
All of my sound options check out, music plays accurately out of both ears, etc.
Help?

fyi: i've tried reinstalling.

Hey Jacobs Mom,

Make sure that the windows is not attempting to play the game in anything but stereo. Windows trying to play the audio in 5.1 or 7.1 tends to cause problems like this. If it's in stereo and you are still have the problem, please let us know.

Thanks!
