hello, unfortunately audio does not work with layout28 (hex 0x1C) with Asus k53sc . I tried all operating systems(high sierra,sierra,elcapitan,yosemite and mavericks). Volume icon is gray and audio does not work. Changing to layout 1 or 3 audio icon works, but no sound. Any idea how to fix it? I would like to have audio up & working. Thanks!
