no sound when ringing

[olefafl]

Today my Diamond (stock Sprint ROM) stopped ringing when someone calls. All other sounds work. I even changed the ringer to see if it would work, but nothing. When I go into the sound settings and change the sounds for rings, text, ect the sounds play, but I get nothing when someone calls.

I called with my other phone (no set ringer) & with my wifes phone (set ringer) both no sound. I also *67 when I called and no sound.
I did a soft reset, that didn't fix it.

Before I do a hard reset does anyone have any ideas?
