sound not working on my iphone 4

Christina,

I had the same problem with my iPhone 4 -- ringer and headphones worked OK but no sound output from the internal speaker. I took it to the Verizon dealer where I bought the phone and they said the problem is most often the result of dirt in the charging/docking port (the iPhone "thinks" it's connected to a docking station and doesn't send audio to the speaker). The Verizon folks used big "toothbrush" with rather stiff bristles and cleaned the port. After the cleaning everything worked again. Try the cleaning approach.

Roger, thank you. I got a dry nailbrush and presto--my sound is working again.

I had the same problem as well for nearly 3 months.

I had tried bring the Iphone into my phone carrier and they sent me to the AppleStore. When I brought it to them they hooked it up to the diagnostic machine and they told me just to restart the Iphone from the factory settings.

This didn't work either. To complicate things more, other "solutions" seem to only yield temporary success. These temporary solutions included: blowing compressed air into every port, various restart combinations, various factory restore methods.

I had nearly given up until I stumbled upon a support post on Apple's website that finally yielded success.

The solution for me is listed as line 7, which reads:

"Check the receiver mesh (which is on the top front of the device, above the display). If it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris."

Apparently, this cylinder shaped, mesh area is in some way tied to what triggers the headphones/speaker selection. I am not sure how, but I can say that after gently brushing it out my sounds are working again; specifically my music is now able to play directly off the speakers and my Iphone apps all play their sounds agian.

Hope this helps you as well!

Hey Roger, thanks buddy... I also faced similar problem as of Christinaheld. Followed your suggestion and used soft toothbrush... Now it's working fine.

Cool. This one worked. Just blowed some air into the docking port and it worked like Magic. Surprising,even apple products do listen to old dirty tricks.

My Iphone 4 volume won't stop turning off I tried blowing in it ill will use the brush tho

Thank you so much, TheFirstRook! I was having the same problems, and everywhere online it was telling me to blow air into / clean the headphone jack (which did work for me on a previous iPhone) or the docking area. These were not working, no matter how much I tried. I read your comment, took off my case to access the "receiver mesh," blew air on it once with a quick little blast, and voila! It works perfect!

EDIT: spoke too soon. It isn't working again. Will try a cotton swab.

I've tried to blow and clean time after time it still doesn't work

I ended up taking mine to the apple store. The indicators showed no water damage so they gave me a new one.

Hi Roger. I tried what you said and my sound came back. Thank you SO much for this because I thought I would've had to replace it

I found the problem. The iPhone thinks it is sending the sounds through the Dock Connector. Why it is doing this I am not certain, but to fix it I plugged my iPhone into my Mac and the sounds were back immediately. I then ejected it from iTunes and the sounds are working fine. This must have reset the software so it now plays the sounds through the iPhone's speakers instead of the Dock.

I this might have been caused be caused I used the USB port on my car to charge the phone. That might have also caused the iPhone to think it was connected to a Dock and somehow that never got reset when I disconnected the iPhone.

Apple should know this because the solution is very simple.

Thank you Roger !! So happy i came across this post b/c i didnt know what to do. So lost i would be without my apple community.. 😀
