Intel,
I recently downloaded divers 15.33.22.64.3621 and I have came across a few bugs with it. The problems that I am having with it is that every so often the sound will not work. I have to restart the computer to get the sound to come back. I also have a problem with the fact that when I use my headphones the sound that comes out the Left side is louder then. I have downgraded back to 15.33.18.64.3496 and everything works fine. Please look in to fixing these issues for the next release.
