No sound when I charge my iPhone?

I just got a new cord for my iPhone 4, but when I plug it into my phone, there's no sound at all. Is there a way to fix this?

Turn it on

Wen u put in the cord you get no notfication tht it charging? Is tht wat you mean like no sound notifying u? Well the means you bought a really cheap cord tht isn't Apple Mfi Certified
