My new iPhone 6plus suddenly has no sound

Purchased iPhone 6 plus five weeks ago and the first problem was lack of sound. Checked volume buttons and settings to make sure then went to individual sounds for ring, messages, text, etc. and most did nothing when clicked. Changed options however still nothing when a call came in. Phone was replaced last week due to software problem and it was a joy to actually hear phone ring!
A week later and I have voice messages for missed calls that never rang. Back to Apple store.

Chat person had no answer. Went into Apple store to learn about the mute button above volume buttons on left. Nothing mentioned when I purchased it, in Quick start guide, initial search I read or when trying to diagnose. Apparently familiar to long time Apple product users however this is my first and while happy to have this solved, unhappy that it even exists to be a problem.

So I would definitely check the little button that switches back-and-forth above your volume buttons make sure that it doesn't show orange or red because that's a do not disturb button, also I would get a can of compressed air and make sure to blow out your charging port in your headphone jack. And some cases actually muffle the sound so that you do miss the calls.

Same thing on my 6S+...temp fixed, went to settings>sounds>ringer and clicked to play my selected ring tone. It played and the other sounds came back. Another BUG!

I have this problem, however my phone rings when there's an incoming call, but not sound for email or text messages. I didn't have this problem before the IOS 9.0.1 upgrade. I've turned my phone off and on and still nothing.

Any one else have this partial problem?

I just tried this and it worked. I wonder how long this will last.

When the screen is locked, there is no sound for email or text messages. When the phone is open and I'm using it, then I get the email and text sounds. Does anyone else have this particular problem?

i has same you .what should i do ?please someboby help me ?

I have the same problem on iPad.

what works for me is to turn off Bluetooth. As soon as I switch it off, the sounds come back. I am guessing the sounds are 'going' to a headset that my phone is pared with, although the headset is not active.

Bokone - following the steps you described worked for me.

I have an iPhone 6. It has latest OS. I was listening to music through my headphones and the music just stopped. I followed the steps that Bokone suggested and it worked.

I tried all the other things suggested here in this thread, but this was the one that solved my problem for me. Thanks

I have the same problem as everyone else here. It's defiantly a big bug. The ONLY fix for me is to restart the phone then the sound comes back. If they don't fix this in the next update I'm going back to Samsung.

This worked for me -

This one is a bit weird but it worked for me for a while and has worked successfully for other people. Squeeze the bottom right hand corner of the phone above where the speaker is. The left Side is a mic not a speaker so don’t worry about that side. Hold that grip for about 20 seconds. This is done as the connector may be loose and had to be repositioned correctly. Yes strange but most of these solutions are.

I had the same issue and used the same FIX. What bothering me most is that this no audio problem keeps appearing every few days, than I have to frequently restart my iPhone6
