I was just sitting thinking this sounds like an equalizer issue.
Its not the speakers as its equal coming out of both sides.
So I was looking around for something that I missed and
I noticed under Sound Preferences - my Internal Audio
device Profile is Analog Surround 4.1 Output + Analog
Stereo Input. That should be 5.1 Output and sure
enough, fixed! Now, how the heck it got changed is
another story.
