Patching and Volume Mixer

Okay so I use the volume mixer to adjust all of the volumes on my PC to reasonable levels relative to each other. League happens to have one small issue with doing this. Whenever there is a patch, the volume of my League (both the volume of the client as well as the in-game volumes) gets set to maximum on the volume mixer, usually resulting in my eardrums being blown out. Is there any way you guys can make League remember its volume settings in the volume mixer after you run patches? I'm playing on Win7, if that makes any difference.
