So as of today, while I'm in the main menu for League of Legends the sounds while navigating through the menus are only played in the right channel. The only similar problem/solution I've been able to find via google is because the audio is set to surround sound. However, I use a 7.1 surround sound headset, always have, and none of my settings have changed for my headset or league of legends so I am confused as to what is causing this problem to suddenly appear.

In fact, when I enable 7.1 on my headset (I usually keep them in stereo mode for LoL) the menu works properly, quite opposite to what has been previously suggested. Sure, this is a minor inconvenience but since I have been playing since Season 1 consistently with one setup I'm just wondering what caused it to suddenly not work as usual.
