iPhone 4 sound not working


My sound has gone off from my iPhone 4. The ringer works but no sound from music, app, YouTube or anything like this. When I first unlock my phone the sounds for a few seconds and then the volume bar will disappear again.

I have tried restoring my phone and cleaning it with a tooth brush at the dock connector, and also plugging the headphones in and unplugging them as the phones sound works fine with headphones or in a dock.

Clean dock port again with Isopropyl Alcohol. Attach USB cable to iPhone, does this help? Consider replacing dock assembly with flex cable.

Your speaker may be blown. The amount for a ringtone to use is very little. The Music or things of that nature put large wear and tear on your speaker!
