Microphone not working when plugged to AUX on iPhone 15 Pro Max

This is a safety hazard to not be able to use hands free because the Apple 15 Pro was not really ready for sale to public without this feature. This is primarily a phone and it must be able to be used hands free in a car.

Apple gave us a product that was not ready for consumer use. Apple fix this problem or I will never buy another of your phones!! I believed in Apple Iphones from the start in early 2000 when i bought the iphone 3. But you need to stop deleting my comments about how I believe Apple is using the public when their devices are not really ready for the road. How dare you stop one of tge most basic functions that made the phone useful for using when driving a car. This is almost as bad as the software for self driving cars like tesla. Fix this problem or lose me.

leaving a comment to say that this is the same for me - I have had an iPhone 13 that I was able to use with a dongle in my car that allowed for calling and talking. iPhone 15 Pro now, with two different adapters, where I am able to hear music and hear the other person talk, but they are not able to hear me.

I haven’t found a solution yet! Someone posted a fix about resetting some things in SETTINGS but that did nothing. And I refuse to pay $40 for a new dongle if that also doesn’t work. I did send a request to APPLE about the problem, I would advise others to as well!

How did you connect the standard headphones (no mic)? My headphones have a male plug, I’d need to add a female2female coupler to this? Better if APPLE would figure out why it happened when they went from LIGHTNING port to USB-C port!

Anyone have a solution? I've tried both the Apple and Google adapters with no luck. Unable to connect external microphone through the Apple USB-C to 3.5mm Headphone Jack Adapter. The phone is using the internal microphone. I'm using iOS 17.3.1. I used this set-up all the time with my older iPhone and lightning/Aux adapter for streaming video with an external microphone. I'm trying to record video/audio using an external microphone. Any suggestions?

I bought the Google adapter. It’s only works with the android. It will not work with the iPhone 15. I’ve tried different aux cables. I’ve tried everything. It is so ridiculous that Apple is sending us to use a Google adapter and then that doesn’t work either.

This fix helped me as well! I went into Sounds and Haptics, scrolled down and tapped “Headphone Safety”, then tapped “Forget All USB Audio Accessories”, and the next time I plugged the AUX to C device into my phone, I selected “Headphone” when the option popped up. Now my phone plays through my car speakers.

I have the same issue with my lightning to aux cable. Interestingly enough, Siri works just fine. I use my headphones to listen to the metronome while the phone mic records. Hope apple fixes this in an update

I have a similar problem. I have a iPhone 15 Pro Max and I have many Apple ear buds with 3.5m connectors that I wanted to use with the 15 Pro but I have not found a 3.5m to usb-c connector adapter that truly works. I have tried the ones listed in these responses and others and found the sound is OK, the pause and Siri feature work but the real problem is none of these adapters support the volume control on the ear buds. I also have several Apple ear buds with the lightning connector and tried a different adapter and found the same issue.

Has anyone come up with either a 3.5m or lightning to usb-c adapter to support volume? I use these mostly for workouts and yard work so the mic is not really a priority.

I was previously using Peterson iStrobosoft app on my iPhone 6 via the headphone jack as a direct input to tune my guitars. No issues at all. I just bought an iPhone 15 Pro and using the Apple 3.5mm jack to USB adapter it seemed to be working as before, and then not. On first plug in - nothing. Then all of a sudden it was working. The next time I plugged in I got the pop up asking if it is a headphone or other device. I selected ‘other’ and it was working fine. Later, when I went to tune my electric 6 string it was not accepting the input. Then when I plugged in my bass, which has an active pickup, it was suddenly working again - with both guitars! On my latest attempt I cant get it to accept any input from either guitar, hence I sought advice from this community.

I tried adjusting in the Settings > Sounds & Haptics > Headphone Safety > USB Audio Accessories, as suggested here, but to no avail. The phone seems to recognise when my headphones are plugged in (although the pop-up seeks confirmation), but nothing registers when the Peterson Adaptor is connected (via the Apple adapter).

So I think this has to be a software glitch with the phone itself.

me too and it’s really annoying to lose functionality with a newer phone.

Hi , i have the exact same problem , pls do update in case you get a solution #iphone15

The microphone on my iPhone 14 Pro Max is not working correctly. It is not clear to the person I am talking with. I have called my own VM and it is not good.

And sound volume on USB-C to Aux is not nearly 60% of sound from Lightning to Aux. this is a problem for those of us greatly hearing impaired!!
