Who I have the same questioned this topic

I have an iPhone 5.  All of a sudden, my ring volume and speaker volume is real low - almost as if it's on the lowest setting.  I have gone into sounds - volume and turned the slider all the way up.  I also did this in the music section.  Hasn't helped.  I've turned it on and off several times, and I've done the hard restart with the power button and front button.  Nothing has helped.  Help!  I need to hear the ringer!
