Iphone 7 plus No Audio Device Found

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.

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

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

All the research I've been doing has pointed to a hardware issue. I'm trying to find out which internal component has failed so I can eventually perform the fix myself. I'm also purposely delaying on the self repair in the hopes Apple will finally acknowledge the issue and repair it on their own dime.

I believe this is a complicated fix requiring soldering skills. Please don’t try this unless you have confidence in yourself. Go to a reliable 3rd party repair store or try another apple store. Write a mail to Tim Cook or senior executives that you are being charged for something that should be free. Please do this if you believe you have not abused your device in any way.

Not at all. It doesn’t require any soldering to reflow a surface mount chip, you just need to gently heat the solder to reform the dried out / flakey bonds. Pros use hot air, but I’ve fixed gfx chips on boards using a heat gun attachment for a gas soldering iron to reflow. Audio IC might be too delicate, although what have you got to lose?

Update: I took my phone to my local apple store in Cairo. They told me that they couldn’t fix my problem because I had bought the phone in Europe. They told me they would ask Apple support to give me a call later that day. When they called, I explained my situation to the guy and he didn’t seem convinced that I hadn’t caused the issue. I asked for another technician to be put on. I explained the situation again and I told him that I would be more than happy to prove to him in any way possible that my phone has NO damage despite being almost two years old. I don’t have a single scratch on my phone. He asked me to bring the phone back to the Apple store and for them to send him a report with photos of the phone. The guy was extremely friendly and helpful. Anyways, I went to the Apple store and they checked the internal cavity of the phone and the exterior and filed the report. Turns out I was right, my phone had literally NO damage physically. Anyways, the guy I was in contact with called me a couple of hours ago to congratulate me that I will be able to replace my iPhone 7 with a new one, free of charge. Honestly, the technician I had was an awesome dude. He personally made the effort to contact me and help me every step of the way. Unfortunately, some people aren’t so lucky with their Apple Support Technicians. He even told me to call him back to let him know I received my new phone and he gave me his contact details. This guy deserves a raise.
