If still unresolved then your device will need to be serviced.

It won't let me edit my original post. I spoke with a 3rd party repair service who we've used in the past. It's the audio IC that has went bad I'm told. The cost will be approximately $125. From reading this problem is something apple was repairing for free for phones out of warranty up until July of this year. Now people are told they'll have to replace the phone.

I too have had this issue since updating to 12.1.2, could not make or receive calls, voice memo not working, siri was absent etc....

What worked for me was to turn off noise cancellation under General - Accessibility. Mine was not even showing up, but I turned on hearing aid compatibility and it told me you can only have one or the other so i assume it turned off noise cancellation. Soft reset by power and volume down and everything works again.... for how long who knows?

Bang on!! Had the same problem, no audio and for some reason can only make phone calls via Bluetooth device. speaking to third party repair shops, This is a common issue in early iPhone 7’s. When speaking to Apple customer service , they will not admit it. Through Apple repair chamber £372 third party £60. It’s the audio port that becomes dislodged due to where it is

For all saying this a hardware issue, I am now questioning that... or maybe it’s both hardware and software. It’s weird, no less. This is the second iPhone 7 Plus I’ve had this issue with. The first, I had replaced through carrier insurance in October. Now it’s happened again. Both times, Apple support has done software troubleshooting and tried restoring to no resolution. NEVER was there mention to try to restore using DFU mode. I read some about this from other sources and decided to try it. I did not even do the restore, but instead just entered DFU mode and the restarted the device from there. Now the issue is resolved! No error in voice memo app, FaceTime and audio calls work! Seems software related to me. I should note both incidents started the same as others have mentioned, after an update.

12.0.1 has broken my front facing microphone.

3 microphones on my model iphone. (6)

test:

1) bottom mic: use Voice Memo app to record.

2) selfie mic: use camera app / video / selfie mode to record a video.

3) world facing mic: use camera app / video / default mode to record a video.

#2 test resulted in a video, static audio and zero voice track.

#s 1&3 tests were normal.

10 out of 10 to Apple customer service. The Genius Bar appointment came up with a pretty swift diagnosis - the infamous Audio IC hardware fault and also a software corruption of iOS. The phone was out of warranty but at 20 months, was under two years old so they replaced it for me on the spot with a new phone.

The audio Ic issue is a fault across several devices where the weak point by the sim tray causes flexion and a ball joint on the IC chip lifts. The software issue may be occurring with that particular update, and there’s no way to correct it except by giving it to Apple.

It’s pretty impossible to imagine any other company on Earth dealing with the issue so swiftly, sympathetically, and totally - even to the point they had exactly my model of phone in stock, despite not having retailed it for a long time. I know everyone has different experiences, but this is mine. I’m just an ordinary customer but they made me feel like I was sitting in first class.

It is a hardware issue. The problem is the master clock line for the audio ic--at times the master clock can have intermittent function---the underlying defect is a loose pad under the chip. It does seem to manifest at update when the device is restarted and does a system check.

Your audio ic chip needs to be replaced it’s a common issue with the 7

All 3 mics and speakers don’t work only can make calls if using Bluetooth headset or my car 🤦🏽‍♂️ But I took my phone in to have it checked out and was told if my phone don’t have damage apple will replace my phone for free if the screen is cracked they will not replace it I have to buy a new one

I had purchased an Iphone 7 for my daughter who keeps in excellent condition. After the latest update, she cannot make calls or hear the caller. The speaker button is also greyed out along with the voice memo stating no audio device can be found. I took it to the Apple genius bar and after passing a diagnostic test, the technician told me that it was the mic. They offered me $250 buyback since it was in excellent condition but wanted to charge me $319 for "new" iphone 7. They also stated that if I had the Applecare, it would be an easy swap. Why should I have to pay for a new phone if the update was the cause of this? An update provided by Apple to improve the phone. I have been a loyal Apple customer for years, but I was very disappointed in the way Apple is handling this. I have read were Apple was taking care of its customers when the issue was presented, now they are making people buy phones and pay for a mistake the company made.

Please try to take it to an Apple store and see what they do. If you didn’t abuse your device they should replace it , since it’s a hardware issue. If unsuccessful try a 3rd party repair store OR write a mail to Tim Cook , Phil Schiller or other Apple executives. This is a hardware issue ,and you should not be charged unless you abused your device.

That might be because when you get a new device from Apple through Apple Care, it's an Apple Certified Refurbished device, not a brand new device. This is the case with any phone insurance, and not persé a bad thing, after all these devices have been checked and should be working perfectly. At least you would expect that it works perfect, but the unofficial knowledge that goes around is that from using the iPhone 7 for several months / years, the connection between the motherboard and the audio chip 'shakes loose'. I do however know people that have had the iPhone 7 for several years by now and never had the issue. So, simply return it again and hope you'll get a device without this issue next time. Obviously you shouldn't have to pay for anything when replacing it on such short notice.

I gave up fighting this issue, left my iPhone 7 (out of warranty) with the mic issue for what it is, and bought a new iPhone XS.

Cant you go to a different apple store , and ask them that you are suffering from this hardware failure?

Sent iPhone7 to a phone repair place on EBay, works great after spending $40
