No sound coming from my iPhone 4s.

I'm also having trouble getting sound.

When I toggle the volume buttons, I get the Ringer & Bell icon come up, but the scale underneath it is missing.

I have upgraded to IOS 7.1.

I haven't tried cleaning the dock 'invasively', nor restoring from back up. I was hoping to avoid the latter, but will try so now.

I'm a bit disappointed that I don't have access to live Apple help phone or chat, as I've had my 4S for too long it seems.

What I finally did was take a can of compressed air and blew out both the dock/power connector area and also the headphone jack really well. The sound has been working since - which leads me to believe that, at least my issue, is solely a hardware issue, not software.

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.
