Client Sound Issue

I'm not sure if this is a bug or not, or if anyone else is experiencing this issue, but if I leave the new client open for too long, the sounds such as clicking things, champion select lobby noises, music, etc., all start to sound very choppy and become filled with white noise. I've actually tested just to see how far the audio quality decreases and it seems that after two days (at least for me) the sound just completely disappears. The only way to fix the sound is to re-launch the client. Any chance this could get fixed?

Thanks, Malifact
