dell XPS 9560 Maxx Wave Audio missing

I just got a XPS 9560 and I could not find the Dell HD audio mananger just like in my old Inspiron. Here is the picture:

I also tried to install realtek HD audio driver from dell and run the file RtkNGUI64.exe but nothing seems to work. Please help me because I'm used to using this feature for every audio activities and now missing it is really uncomfortable
