I just finished building a new computer and am having issues with the sound. I have to keep my volume levels down to about 6; if I go much higher, the sound is way too loud. I've attempted to adjust sound levels, re-download drivers, playing with the enhancements, changing the bit rate and depth (which I don't even know what those do), and switching head phones. I'm currently using a pair of Polk 4 Shot headphones with an audio/mic splitter.
One of my two monitors does have an option for audio in the back, and all the levels there seem normal; however, I am missing my mic input.
