No sound coming from my iPhone 4s.

I had the same issue. After countless resets and what not, I did the random button pushing thing, and I cleaned the ear jack thing with a q-tip and I cleaned the dock with a tooth pick. It took a few minutes, but it works now. SO thanks random button guy.

Issue is headphone port microswitch, not a software issue.

Try rapidly unplugging and replugging headphones. If no joy then repair is required.

That trick didn't work with mine. All that worked was sliding a credit card thick item between dock/charge plug and back of phone. What seems to have more permanently fixed it was blowing it out with compressed air.

thig guy is frekin brillaint i tryed all of the above sugestions no no avail even dropping phone nothing worked except this http://apple.stackexchange.com/questions/85696/my-iphone-thinks-its-always-docke d-volume-slider-disappeared-with-no-audio-o i didn use a key i used a spark plug adjuster because there more plyable didnt want to damage connector twisted a couple of times and presto wamo working great

My friend contacted me this morning at 6:15am saying that she had a problem with the sound. It worked briefly but then stopped again?

I've been told just now that the sound works when the phone is unplugged but stops working when it's plugged in.

About half an hour ago, I just realized that my iPhone4 has no sound except the ring tone. After trying every thing I did what btwoodward suggested. I took my can of air and cleaned both the headphone jack and power dock.

And it worked.

So there is no software or hardware issue. It’s just a dust clogging the connectors in some way issue. I can blame my two year old for that.

This is what I did and it worked. Go to setting/general/reset settings. After I did that my sound for music and videos was back on. Hope this works!

thanks.. I used toothbrush but no avail. But it works with a pin!! 🙂

Worked!!!

Hey Szayat, I had the same problem too. A few months ago the sound on my phone would go for about 20 minutes and it would come back on after that. then, it just suddenly stopped, so I thought nothing else of it. But last night I was on my phone and I wanted to watch a video on Facebook and there was no sound what so ever. So I rebooted my phone , turned it on and off, changed all my settings and it still wouldn't work. And the same problem as before , it came back on after about 20-30 minutes. I noticed there was a problem when I couldn't hear the clicking sound when you type in you're password and when you're writing. So I got a hair clip ( because it was the sharpest thing that would fit in the charger hole that I had) and I cleaned out the charger hole, and so much dust and dirt came out of it, it was unbelievable! I also blew into the charger hole to get out the rest of the dust. But after that it still didn't work so I rebooted it ( by holding the lock button and the home button at the same time) and played around with the mute button on the side of my IPhone 4s , Then immediately it worked and I have had no other problem since. I hope this works for you guys but if not I suppose you should look into taking it to a professional. :)

I had the same issue. I tried most of the suggestions listed here, including cleaning out the connector port. Nothing worked. I was considering disassembling the entire device and replacing the connector, but I decided to try cleaning it one more time. I used Isopropyl Alcohol this time. I did a thorough cleaning of the connector port and the audio jack port. Problem solved!

Getting a small enough implement into the connector port was a challenge. In the end, I halved the cotton on a quetip, pulled the top out some and stuffed the lose end into the port. Then I used a tack and cardstock (business card thickness) cut small to work the Alcohol through.

I just wanted to update everyone that cleaning works.

I spoke too soon. The problem returned... NOT SOLVED

I have an iPhone 4. I tried cleaning the charging port and, although I got a lot of lint out of there, it didn't help. I tried the freezar for 5 minutes, etc, etc, etc. I called ATT and the guy was nice but treated me like an idiot. After a while, and trying some things, he said that maybe I should go to an ATT store. The only thing that worked was to put a small reward points card, the small one that goes in your keychain, inside the charging port, the bottom part of the pins at the bottom of the phone). I push it in, mostly on the right side, and then up. I saw the volume bar right away. I tried several times, until it worked for good. It's been two days and it still works. i added the card to my keychain again just in case.
