[BETA CLIENT] Audio bug - performance hit in game

I decided to give the beta client another chance, this time with low performance mode enabled. Everything was good at first, but by the 2nd or 3rd game the audio began to skip and scratch during champion select. I entered the game and audio and play were both stutter stepping. The FPS reading said 60 to 90 FPS, but I was skipping on the screen. Audio was scratchy and skipping, though not every sound.

I tabbed out of the game and killed the beta client, and then all issues went away. I used that fix in two different games. In the second game I restarted the client and logged back in before resuming my game and the audio issues didn't start back up.
