It's easy to loose the mixer. In the screen shots below, top is an embedded mixer, middle is floating mixer and bottom is no visible mixer. When you have the floating mixer, you can lose it by pressing the red "X" (2) to close the mixer window. You can press (1) to embed the mixer.

I didn't realize it until recently but there is a mixer button (3) that opens the mixer window.
