i finnaly fixed the damm thing cannt belive it i thought it had been water damage or drool damage due to my 18 month playing the baby apps i cleaned the bottum speakers with an old toothbrush and the blow into it from one speaker at time very hard and it F ing worked happy days it was wrecking my F ing head hope it works for u

I had this issue aswell - OMG it's been driving me crazy! My phone would ring and play music in the car, but no other sound, no text tone, no you tube sound no music without speakers. I tried the tip below regarding cleaning the bottom speakers - AND IT WORKED!! woo hoo it's surprising how clogged it gets just from being in your pocket! As suggested, get a toothbrush and something fine and sharp, scrape the crap then brush away :-) I hope this works for you too!! xx

I dont know how helpful this is but my iPod touch 3rd gen does that it thinks the headphones are still plugged in and with it being jailbroken very inconvenient try rebooting it..

if that doesnt work send it to apple it is a hardware defect

go to SETTINGS and then enter MUSIC and go to sound restrictions maybe your sound is restricted all the way down on mute.

If you have a warranty send it to apple if it does not help.

It looks like a software issue, try restoring it.

I also have this problem with my iPhone 4s (6 months old). For some reason my phone has suddenly stopped playing music or any sound other than ringtones through the speakers OR headphones plugged in, however if I receive a call it does ring and likewise if I am choosing a ringtone in my settings, it also rings outloud.

However play any of my music or watch videos on YouTube or online and it is completely mute whilst the song or video can clearly be seen ticking along.

I am unable to increase (or decrease) the sound bar using the side control buttons.

I have checked sound limits in settings as One person suggests above however I had no restrictions on it so it's not that. I don't think I've got my phone wet in the last few days but it has been raining a lot so maybe a tiny bit of atmospheric moisture has entered it?

It is strange though that it will play ringtones perfectly well- crystal clear as ever but no music. Frustrated. Any further advice before I send it off would be very much appreciated. Cheers g

Hi folks. My issue has been resolved after no real help from apple or vodafone, I tried restoring it through iTunes and then synced it with my back up through iTunes. After a couple of times doing this it starting functioning normally again altho weirdly not straight away but a few hours after I restored it. Think there is just a gremlin in these new and cheaply manufactured (in china) iPhone models. Not very robust and I'm not very impressed but at least this now works. Good luck!

I also have the problem. Will ring, but no music, my GPS lady doesn't talk and any of the alerts aren't working either. I talked to Apple and they said it's a software issue, however I did not pay for the support so I am screwed. I will have to pay $160 for them to fix it!! Sound's like their problem.

I had faced this problem after my iphone 4s was water damaged. I opened it up and cleant the dock with alcohol( Please use a better chemical to clean) It worked for few hours and then again got docked( No sound on ipod etc ) I again opened it up and cleant it and let it dry for some time and now its working fine no problem at all. There is also a chance of the dock connector not functioning. You can easily replace it if possible and your problem will be solved

Exactly the same thing, Music would play with various headphones, but not through the main speakers.

Ringtones, Alerts etc were unaffected.

So I got a dry toothbrush and scrubbed the speakers clean and now they work fine!

Thanks to whoever provided the answer first!

Had same problem- music playing through speakers did not work, but ringtones did work; music with headphones and bluetooth did work.

I backed up, did a restore, and restored all previous data etc.

That was it - it worked!

problem iphone4 ringtone ok but sometime ipod sound off solution
