Hi, I just purchased a new Predator G9-593 laptop a few weeks ago and everything seems to be working extremely well exceptf for some sound issues. Overall the sound is fine in video and music, but when i run even a mildly demanding game (i.e. Portal 2) I have a very distracting crackle sound. On more recent games (Agents of Mayhem) the sound crackling is even worse. Also, when the laptop is plugged in, the crackling noise increases quite a bit during gameplay. I've tried the basic troubleshoots such as reinstalling the Realtek drivers; running 'troubleshoot sound problems', changing the driver to 'High Definition Audio Device'; and rolling back to an older Realtek driver. Nothing has worked. 
When i run 'Troubleshooter' everything tests fine, but it comes back with the following caution symbol;
I'm not sure if this means anything....can someone please help!!!
