How come my iphone 4 speaker isn't working after updating to IOS6?

Its been like a couple of days since i updated my phone. Earlier i was listening to music then all of a sudden it stopped. I looked at my phone, the music was still playing but there was no sound. I can hear my ringtone and i have to use my speaker to listen to my calls. But the speakers arent working for my music, videos, keyboard clicks, phone lock, etc.

  • Why won't my iphone 4 send pics since updating to iOs6? I always could send pics with no problem. Then one day me and my friend both updated to iOs 6 and now both can't send pics to anyone. I then updated to iOs 6.0.1. And still had the same problem. I have AT&T by the way. But anyway I also went in and set up my iMessage I believe it let me send it to someone with an iPhone but nobody else! HOW DO I SEND PICTURE MESSAGES TO ANYONE WITHOUT ANY PROBLEMS LIKE BEFORE!
  • Why isn't my iphone speaker working? As far as my iphone is concerned, it thinks that i have headphones plugged into them. But i do not. What could i do? I tried restarting. I tried killing the whole battery and recharging it to 100 again but no luck. It also stops me from hearing phonecalls from the iphone itself

  • My iPhone 4S speaker isn't working I got my phone a little over a year and a half ago. I usually listen to music without headphones coming from the bottom speaker. Yesterday I had it on loud and it made a cracking noise and stopped working. I tried it again on a low volume and it worked fine it was just a little fuzzy so I turned it up and the sound made the same noise and doesn't work. The headphones work and it just stops in mid song. Any ideas will help thanks!
