Since then, audio is not working, everything seems fine visually, I have tried many tutorials to no avail, everything seems to be in working order, but no sound comes out of speakers or headphone. I have also tried an external usb audio driver, no sound comes out of it either. It seems to be recognized, there is no indication that it should not be working.
