iPhone 6 audio line in not working.

[matthewleeblair]

iPhone 6 running iOS 11.0.3
When recording video with the Apple headset, the audio is recorded through the iPhone's internal microphone instead of the headset's microphone.
I noticed this issue when using a headphone jack adapter that should have allowed me to send audio from a different source into the iPhone.
When using this device (iRig), the iPhone would record audio only using it's built in, internal microphone and not the audio coming through the adapter into the iPhone's headphone jack.
This is driving me crazy. I even went so far as to replace the headphone/lightning port assembly in the iPhone. Still having the same issue.
That made me think it was a software issue. Maybe somehow iOS 11 is doing something to cause this, since the newer phones don't have headphone jacks. Maybe it's an oversight. An unforeseen problem for iPhone 6 users upgrading to iOS 11 (didn't even realize I was updating to the iOS 11 when I did. I had just repaired the broken screen of this phone. When I connected it to set it up and restore it, I didn't think about upgrading to the newest software.
I do not have this problem with my iPhone 6s Plus. Works fine using the Apple headset or the iRig.

What in the world is going on? Any suggestions? I can't find info on this problem anywhere on the inter-webs. I tried creating a thread on the Apple Discussion site, but it wouldn't load for some reason. Mac-forums... you're my only hope.

If you make a phone call does the headset mic work ok?

Have you tried 3rd party software like FiLMiCPro ? Where you can explicitly select different audio sources ? If so, does it work, can you select the iRig or Headset input?

 

[matthewleeblair]

I have not. I'll try that today, and let you know the results. Thanks.

 

[matthewleeblair]

The app you suggested is $15. Is there another app that will let me test this that is free or cheaper?

Try Pro movie recorder

[matthewleeblair]

I downloaded ProMovie Maker on the phone having this issue (iPhone 6) as well as my iPhone 6s Plus which is working correctly. I was not given the option to select the headset as an audio input on the iPhone 6. I was given the option on the iPhone 6s Plus. So for some reason, the iPhone 6 is not recognizing the audio in.

If a software restore hasn’t resolved this I can only conclude this is a hardware fault

 

[matthewleeblair]

I have restored the software of the phone and updated the software. Problem continued. Also did it with the original headphone jack and the new headphone jack that I recently installed. What other hardware could cause the problem?

 

[mrplow]

The logic board and soc are what controls everything ......

Are you definitely using tssr jacks for the things you’re connecting? I.e. the plugs have 4 sections, 3 bands.

 

[matthewleeblair]

I'm not using TSSR jacks, but I'm definitely using TRRS jacks . The Apple headset is TRRS as well as the iRig. Maybe it is something within the logic board. So weird. I just tried on another old iPhone 5s and it works great. Going to just use that for my purpose. Facebook Live streaming with an audio line from a mixing console. I'll use the defective iPhone 6 for running another app that just needs to use the headphone jack for stereo audio output. Would still be interested if anyone knew a trick to making this work though. Thanks for the help so far.

That’s late night dyslexia for you
Not sure there’s a trick to it though. Would be interested to see if lightning audio in works

 

[matthewleeblair]

I don't have a lightning to audio adapter. I'll see if I can borrow one to try that.

I had the same problem and could't solve it

Is that well thought out ringer off switch in the wrong place?
