IOS 11 Sound Problem

If we're still talking about the same issue here, this was resolved for me later last year...

I have this problem on my new iphone 8 plus. I had it replaced two weeks ago and my new one just started doing it again!

Did you buy a new Apple phone? Bingo

Ali

I just had this happen out of the blue with my 6. Seems like it's been going on for people for a while now...still no updates or answers from Apple?!

Hey! This worked to me!

Since update, my earpiece stopped to work and I had to use loudspeaker to listen to my counterpart.

I had turned off airdrop, noise cancellation (in accessibility settings) and data roaming (in cell data options inside cellular/telephone settings)

days before (don’t know if it had something to do with this issue, but people said so in another post) and yesterday I followed your instructions:

• Go to Settings
• Cellular (in Portuguese, “telephone” in other language I think)
• Turn off Wi-fi Calls

Turn off the phone

Now I listen who is calling me normally!

Thanks!

Yeah I noticed this after I posted sorry! There's a more recent one for the actual non beta one.

Here's a link to the more recent one: https://www.digitaltrends.com/mobile/how-to-downgrade-from-ios-11/

My phone has stopped acting up since my maybe 4th reset yesterday? I haven't had any call issues. I am constantly testing the volume to see if the icon pops up. so far all is well so I haven't had to try reverting yet.

This sounds plausible. The problem is that I no longer find the WLAN (Wi-Fi Calls) setting. Could the problem be related to a change of carrier? My new carrier may not support, but it was with my old carrier. If the phone detected that the service is no longer available it may have disabled the menu inside the settings, but forgot to disable the service itself. Meaning it is trying to use it even if it isn't supported by the carrier/network. Still not sure, though. Since I'm not sure I were connected to Wi-Fi some of the times.

Yep, having the same issue with iPhone 6s with iOS 11.0.3. During the regular call via the Phone app, I don't hear anything and a person doesn't hear me. Connecting AirPods and trying to call again doesn't help, still no sound on both sides, and after turning iPhone off and on again the problem is temporarily solved, but it comes back again after a while, and calls via other apps like Skype or Viber are working fine, so it's not a hardware issue and it affects only the native Apple Phone app. And I have never faced it before updating to iOS 11.

I think my phone finally works. Been at this for a month. Terrible call on Monday almost cost me my job. Apple, this is infuriating. Everyone else, try this:

Turn off phone noise cancellation (settings, general, accessibility, phone noise cancellation)

Turn off cellular voice 4G (settings, cellular, cellular data options, enable LTE, data only)

Turn off WiFi calling (settings, cellular, WiFi calling)

Reset network settings (settings, general, reset, reset network settings)

Network settings may restart phone. After that, reset again by holding Home and power button until after screen goes black and you see the Apple logo.

Good luck!

My 6s iphone is dropping sounds to get moving for scheduled events. Also, the swoosh when sending a text message gets silenced. My phone works. This silencing of signals is fixed by restarting. It’s like a bug is setting the Do Not Disturb logic on, but the switch on the side has not been moved nor has the moon set by swiping up on the screen been changed. I listened to iTunes and Audible with wired earphones and wonder if that is related.

Do you have same applications installed on both devices? I suspect that there is problem with CallKit in XCode. I had problem with sound when i had Whatsapp. I deleted app and my sound got better for like 50%. Still sound is lower than it used to. But it would give me usefull int if that's the real reason. (now my sound is constantly good. not great but good). That give me reason to suspect there is problem with this feature.

So a couple of weeks ago I took my phone in to Apple for a battery replacement. I was hoping that the sound issues might be related to the battery...

Anyway.. during the battery replacement, the 'Genius' screwed something up and bricked my phone.

So.. Apple gave me a brand new replacement phone for free.. result.

I didn't restore from backup on this phone so it's about as fresh as you can get.

The call issue still happens.

This is 100000% a software issue.

I've noticed that it only happens in certain locations (my home being one of them unfortunately) and at certain times (evening being the worst)

The mystery continues...

Have just updated to new 11.0.3 version in my IPhone 6 and nothing happened! No sound on ear phone, only works on loud speaker...

Dunno if this will help anyone but I found this way to revert back to iOS 10.3.2 , going to give it a shot.
