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
