Sound on my iPhone stopped working?

I was watching a video on YouTube and it just stopped working. It was working fine just a minute ago and now it wants to start acting like a little punk. I tried turning on the music and it said can't complete action. Please tell me there's a way to fix this crap?

Ah its more then likely a blown speaker. If the speaker made a crackle or pop sound then you blew a speaker. If it just stopped working without any noise it just stopped their may be something wrong with the software on the phone to fix this i needs to be restored and on the latest software, Or something like accesive heat may have caused a sauter to come lose and jacked up the speaker in which case you need to take to an apple store

  • Why did the sound on my iPhone 4 stopped working? Okay so I was in the middle of watching a YouTube video on my phone. And then all the sudden at 1:30 AM my sound shut off. I was so pissed! So I looked at my side switch on my phone, it was off and I looked at the disturb button in settings it was off! An when I get a message no ring! There's no sound AT ALL. I tried turning it on and off it didn't work and I also tried double clicking the home button and minusing all of my apps didn't work!

  • Sound on my IPhone 4 stopped working randomly? Okay so I was just on my phone watching YouTube video when all of a sudden when I went to watch the next one it just stopped working. There was no noise that indicated something was broken, so I just assumed I should put some earphones in. When I put my earphones in it didn't make a difference I still don't have sound. I'm on IOS7 and my iPhone is in good shape.
  • Music and sound has stopped on all my apps on iPhone 4? My iPhone has been working fine. But recently I have lost all sound on every single app. I've checked the settings on each app and sound is switched on for each of them. My ringtones and everything else still work.
