Iphone 4 speakers don't work? - 1

I have 2 problems:
1. When I receive a call, it's hard to hear what people say, it's like they are whispering
2. Sometimes the speakers don't work, and when I watch videos on youtube, it says dock connector instead of iphone. The problem is still the same when I plugged in the earphones.

Need to be check

  • Will my iPhone 5 adapter work with my speakers? I got an iPhone 5 adapter and I tried plugging it into my speakers and even though it says its charging, the music won't come out of the speakers, and that's happened for every device i've tried to use it with.Am I doing something wrong, or do I have to go out and buy a whole new speaker?
  • Why won't the speakers on my iphone 4 work? I just updated my iphone4 to ios 5 and it seemed really cool at first but then i tried listening to music through the speakers on my iphone and nothing would come out, it only works with headphones, help? Also can i get siri with this new update?
  • Why won't the speakers work for my iPhone? I have an iPhone 4 and after the 6.0.1 update, the speakers stopped working; I checked everything, nothing was out of place. However, when I plug in my headphones, the speakers work perfectly. What's wrong with it and is anyone else experiencing this?
  • Sound in iPhone 5 speakers do not work? Just asked this question but i have found out more information. Okay so my phone speakers were working earlier but now they are not. Just bought it not even 5 hours old. They do not work, they were working on youtube but now they are not working on any app, siri, or even when calling i can't hear the other person. However, plugging in my headphones i can hear through the headphones. Does anyone know if this is just a firmware problem, or is it defective?
