Audio channel change not saving

Not sure if this was reported or not, but everytime I start the game I need to change the audio channel to the one I want the game sound comming out from. The game UI shows the one that I had previously saved, but the game sound is not comming from it.

Not a big deal, but it's sligtly annoying since I have to restart the game every two hours to fix my frames droping considerably T_T.
