Thank you very much for taking a look at my config file.
 
	I deleted the USBPorts file which I have no idea why it was there.
 
	But the audio is still not working on headphones.
 
	And its worth mentioning that it only shows one output device, so if I plugged the headphone, "Internal Speakers" device is gone and replaced by "headphone".
 
	The sleep mode did not work either. Btw, I am not sure what you mean by "dual graphics enabled", because I unchecked (inject Nvidia), not sure if that is enough to disable the Nvidia card.
 
	Thanks again
