Hi, I have an EZ Book Pro 3 (v4, the one with the hatch underneath for SSD and also has the precision touchpad) but I have had no luck getting the equaliser to increase the sound. I’ve tried all the drivers in this post and also changed the audio in the bios but can’t get the option. I’m not overly impressed with the sound so far, even at 70% it sounds a bit distorted. Thanks for any help.
