I just upgraded my nforce drivers (I have an ASUS A7N8X Deluxe) and for whatever reason the audio is VERY quiet. I have fiddled with all of the NVMixer settings, as well as the general volume settings, but havent had much change. All of the sudden I have to crank the volume know on my z560's to about 75% when it used to be too loud at about 45%! Does anyone have any thoughts on this?
