IOS 11 Sound Problem

I think you are right! I also have the Tinder app. Haven’t been using it lately and the phone seems to be ok. I just opened Tinder to test and guess what, the phone becomes quite buggy! Definitely has something to do with Tinder.

same here- definitely a bug.
I spoke to Apple Live Chat and they checked the Diagnostics and said nothing wrong, but then says they don't think its a software bug and probably hardware problem and get it checked at service center.

iOS 11.2 Beta 2 seems to have fixed the issue.

If Apple would only publish some actual release notes for beta software we'd know if there has been any attempt to fix the issue but that's definitely asking too much.

This problem still exists after an upgrade of my 6s+ to 11.1. Voice works OK immediately after a restart. However, after a short random period calls may run for a couple of minutes, then inbound voice to the internal speaker shuts off. This affects Bluetooth i.e. in the car or all calls. This affects all calls - from cell or landline. Redialling gets the other party back, but disruption occurs once again. Today one call required 4 redial attempts to complete. the problem did not manifest itself in 11.0.2/3. Have installed, reinstalled with 11.1 twice - trying 11.1.1 today. Not to mention the huge waste of my business time trying to get a mission critical item of equipment to function as it should.

I'm afraid Apple software release quality has reached an all time low, pushing out a release with this many issues, this poorly tested would get most release managers at credible software companies fired. Don't get me started on High Sierra issues! Buck up Apple!!! Time to sort this out or start losing the loyal customer base(17 yrs) as I am seriously considering Android as my next phone platform.

Over a month of not being able to make a phone call. I have a case number with Apple and they call me every few days to ask a few questions and see if the various updates have fixed it. Has actually gotten worse, can't make or receive phone calls at all. I can confirm that Apple service team members have read this thread. When my advisor told me this was the first they had heard of the issue several weeks ago I directed him here and he read the first few posts out loud. My 1st "senior advisor" has already passed me off to a 2nd "senior advisor" who doesn't have an answer. I have been to Apple Store who has run diagnostics and verified this is definitely not a hardware issue. When I have asked them to replace my iPhone 6 with a working iPhone 6 that actually makes phone calls the advisor has ignored my question twice. I own 3 iPhones, 3 Apple Watches, a 27" iMac, an iPad, and an Apple Pencil and I will NEVER buy another Apple product if they don't fix my phone that their own software has immobilized.

I have similar problem after upgraded to v11.2. After a few round of restarting my iPhone, it does not help.

Out of sudden, I found out that the phone has been "muted"..... after I tapped on unmute, the keyboard sound, ringing sound is back to normal.

Not sure why the upgrading process muted my phone.

My iPhone 6s Plus which had the intermittent no audio problem for incoming and outgoing calls since iOS 10.3.3 seems to be stable and working again normally now for the last couple weeks, ever since I think iOS 11.1.2 was installed. Nice to have it doing its primary function properly again!

I also replaced my phone and after two weeks the new phone started doing it. I also want to note that my original phone, I had the problems w, started doing it three weeks in and I replaced is after a month and a half. REPLACING YOUR PHONE DOESN'T WORK, save your time in the future!

The folks over here seem to have a solution:No sound after iOS 11.0 and 11.0.1 Update

I now use the speakerphone for all calls unless privacy is an issue.

I have an iPhone SE and every time I use a set of headphones with a microphone, the microphone doesn’t work, and Siri will pop up constantly without me doing anything. I tried to turn off Siri but now it’s voice control instead. And it’s not only my set. It’s EVERY set of headphones with a microphone. It also will start playing music randomly when I’m listening to music but it will play SUPER fast and it’s pretty scary. And it all started when I updated it to IOS 11. I have resulted to using my old set of headphones without a microphone but please get this fixed! I’m not sure if anyone else is having this problem so I don’t know if it’s just my phone or not. Please help!

That’s BS, it’s the new update that’s causing these glitches. Everytime an Apple user updates there old generation iphone, it starts to randomly glitch. My iphone goes deaf when making a phone call and I have to reset my phone in order to get it working again. I’m seriously considering switching to Samsung.

Yes - exactly. And the tell-tale-sign it's going to happen again, I've found, is when there's no visual indication on the screen when using the side volume buttons.

I have noticed - as I use Airplane mode at night - that this now also turns Bluetooth on after deactivating (Airplane mode). So there may be a connection there. But I have failed to replicate the issue so far.

My iPhone 7 has suffered the same fate. Worked fine until the update. Now any app that requires connection to the microphone doesn’t work. Including FaceTime, Skype, Voice Memos, phone, and guitar tuner. So i’m Now having to make calls via the iPad, while I wait for the next update.

Seriously Apple, desks should be getting cleared for this honker of an update. The engineer snag list should read thus:

———————————

Question 1: Does the iPhone still work as an ACTUAL PHONE?!

(Note to engineer - If answer is Y then proceed. If answer is N then please start again.)

———————————

Please Apple. Please. Sort it out!

I have the same issue with the iPhone SE using iOS 11.2. The audio does not work on either end of the call. However if using FaceTime or any other app to make calls there is no issue. Also this issue arised after upgrading from iOS 10. It seems there must be some software bug that Apple needs to attend.
