Ok, your phone is in do not disturb mode. That is the round circle with line next to wifi icon in status bar. If you drag down notification bar or tap volume up, you should see options to turn off dnd. This will enable volume slider.

SOLVED (for me)
Is your phone always face down when no rings come through?? Do you have MOTO app?
Check your Moto Actions settings:
