I'm having the "no ringing" problem as well, I don't have any "My Ringtones" folder. I've always had the "no ringing" since early builds of 4.x (maybe like 4.2 or 4.3 or something?)

I always set my ringer to be "vibe then ring", not sure if this could be the reason why some people hit it and others don't. I could try putting it on regular "ring" and seeing if that helps.

Just thinking about what could make the ringer stop working, what about the "mute ringer" accelerometer gesture (ie turn your phone on its face while ringing)? Maybe the driver for that is falsely triggering mute, I wonder if there's a way to disable that gesture.
