Xperia T and CM11/12 - Headphones' mic not working. Any idea why?

So, after working out a couple of issues, I managed to have CM11/12(WhiteNeo's version) run pretty much fine on my Xperia T. The only problem I have is that the mic on the OEM headphones doesn't seem to work. For some reason, the sound does come out through the headset, but the mic simply doesn't pick up any sound. Tapping on the phone does work, so I'm guessing the buil-in mic is still working and the phone doesn't switch input properly. Any idea why this is happening and how I might be able to fix it?
Keep in mind that with the latest stock ROM the headphones work fine and that my built-in mic has started to fail on me a couple of months ago and now I literally have to scream into it to have people hear me. Therefore, headphones are the only option I have to use the device as of now.
Cheers and thanks.

Microphone doesn't work

Hey folks,
I had the problem with the stock ROM and now I have the similar problem with jackeagels 5.5.1 (SM-G800F).
My microphone works sometimes and sometimes doesn't. People I want to call can't hear me. Eventually after a few calls they do. This is a state I don't want to stay in so does one has any idea what the problem could be? A while ago I pulled some dust out of the mic hole (with a needle) but that doesn't seem to be the problem here

Mines always been dust in the hole. Get compressed air can and blast it. Very annoying.

Hey Guys!
I have a similar problem but only when I use the internal mic, the problem does not occur when I use my headset.
Sometimes, the people I'm calling say that they can hear me very quietly.
Mostly, they say that they hear a constant noise or sound like a "bom bom bom" which is in the background. I can't hear this sound myself and as I said it does not occur when the headset is plugged in.
Any help is appreciated!
Regards, Jens

What phone model? What OS?
The main mic is at the bottom, near USB port. Recording a voice note without earphone, of course, works? The mic hole is dirt or blocked somehow?

Thanks for your reply.
It is a G800F with CyanogenMod 13.
I tested the issue after my initial post with the voice recorder in detail.
So the sound is a kind of buzzing like in the early days of mobile phones when you put your phone near a radio and you get an incoming call.
When I record with the voice recorder, then I hear the buzzing. It is stronger when I say something and quiter when I record silence. Then I also made the same test with my headset, and, unfortunately the buzzing also occured. The intensity was bit lower I think but the sound was there.
Unfortunately, I never tested it with the stock rom. Could this problem be related to a software problem? I'm not sure if I backup my CM and install a stock rom for testing...
Thx!

Yeah, the best way to mak sure it's not software is backup and going back to stock. If it still doesn't work then you have a hardware issue almost certainly...

Microphone not working in call. Please help.. :(

Suddenly my Microphone not working in call. People at the other end can't hear me at all (both normal or in speaker phone). However if I use wired headset or Bluetooth headset in call the everything is fine.It was working fine (I was at CF Rom sutl44 with exposed) then it suddenly stop working since a week ago.
My phone is Verizon Droid Turbo XT1254 bootloader unlocked with sunshine.
At first I thought that maybe my mic is dead but it is not. The voice recorder app (Hi-Q MP3 recorder) can still record from the mics without problem.
I read a lot of this issue and mostly because of software problem, so I tried all that I can think of.
I have reset my phone, even do a full wipe and start clean install but the problem still same.
I flash full stock odexed firmware (sutl44 or 49) with same result.
I flashed resurrection remix rom (the latest) still same problem.
I changed build prop as per some people suggest but still same problem.
From the hardware side, I disassembled my phone and clean mic holes, check mics condition, all seems fine. When I tried using the voice recorder it can register any sound or even touch so the mics are working and sensitive.
FYI, this phone has 5 mics, I checked and tested (with voice recording) them when I disassembled the phone. All are working fine.
I'm really desperate right now.. I love this phone and this is my main phone. I will appreciate any help or suggestions.
Maybe some ROM recommendation that may fix the mics problem.

I just flashed RR Marshmallow to see if I get any luck but unfortunately no.. mic still not working in call.
I tried to remember when this problem start to happen.. I guess it was after I install GravityBox in Xposed and start played around with the GB settings.
I have TWRP backup before I install that GB, I tried to restore the backup but still mic not working in call.
Did Xposed can change something very basic (like a 'driver' in windows) that can't be changed back by re-flash or load a TWRP backup?
Because somehow I think that this 'driver' or 'library' for mic in call is bad or gone.
Please.. any suggestion?

This might be a long shot, but I just had the same issue. After making a call using Google Hangouts, it started working again for me.

I have tried that since I mic is not working.. still problem

tertiary
Remove your tertiary microphone. It is the lower right when looking at the back. After this you must ground your audio output pin or you will get buzzing sound during recordings and conversation. This pin will be lower left out of the four where microphone was removed, there will be a chevron shape beside it which is a convenient ground location. This problem as far as I can tell happened after a security update from Verizon. I realize this sounds like a bogus fix but it made my phone work GREAT. This microphone is picking up your voice as well as the main mic and causing noise reduction to the point of no audio.

Since it's a software based issue, flashing a ROM different from stock firmware wouldn't fix it? He said he tried flashing Resurrection Remix.

BHB27 kernel's problem
I don't read your post carefully, so I don't know if your ROM and kernel is same to me, but I have similar problem in last few days. Finally, I find the problem is the custom kernel, the lastest BHB27 kernel, when I flash the old version custom kernel, the problem is solved. I hope this information can help you.
My ROM: http://forum.xda-developers.com/droid-turbo/development/rom-mpg24-107-70-2-brazilian-6-0-1-t3426234
Kernel: http://forum.xda-developers.com/moto-maxx/development/kernel-bhb27-kernel-t3207526
The new kernels have problem, so I flash back to BHB27-Kernel-V201-8-M.zip

i was able to solve the issue by plugging in a headset and then unplugging it. sometimes some dirt/junk get stuck in there, and the phone thinks that it is plugged in, thus muting audio out except through the jack.

I have the same problem, you fixed this problem in your phone?
I try RR (Android L, M and N), CRDROID (Android N) and NX (Android M). In all of this ROMs, I have the same problem.

can you give more details about the problem that you faced?

After nougat update in Moto M mic not working.
I was not ready to do a factory reset. But there is no other option to fix mic issue after nougat update.
So, last night kept back up of all important folder and run factory reset without automatic restore.
Now, everything looks fine to me. Incoming and outgoing calls are working fine.
So, I am suggesting everyone to do a factory reset, this is one and only option to fix mic issue.
Thanks,

Help Needed with sound problem

I have been using my G Play Mini running nougat Aospa ROM 7.3.0 . Everything was fine. I used the alarm clock,music and video apps regularly,and suddenly all the sounds of my phone does not work. First I thought it was only the microphone as It would not record any sound on my voice notes but then I tried to make a phone call and to play music and speakers would not work also. After that I tried plugging in my headphones and the phone would detect earplugs connected but neither the sound or mic works. I reinstalled the stock firmware from 4.4 to 6.0 and nothing.Though i found out when playing FM radio in loud speaker mode, the rear speaker worked fine. Nonetheless, its pretty weird all the speaker and mic stopped working at the same time.Bluetooth speaker works fine though. I even tried using various apps to boost the sound but still at zero. When i try playing music there seems to be a noise like hissing sound and after sometime the area around speaker gets hot. It has been troubling me for days. I even took it to customer care for help, but they returned it to me back saying it cant be repaired.
Has anyone other faced this problem ? Any help or suggestions would be gladly appreciated.

there is a app in playstore which checks hardware functionality try it or use ussd code to check hardware functionality to conform its hardware issue.

Thanks for the suggestions, i tried like 10-15 apps to boost sound or amplifiers and to check if any of the hardware part was not working or not. Everything was on sound condition. but no sound. that was until 3 days ago. i tried to change the sim to another phone and restarted it, was working for a minute and then it went dead. Currently on the workshop trying to figure out what happened after i did everything i could at home. No charging, no forced updates when buttons pressed nothing. I jst want it to be working cause its one of my fav device. will get back here if i get it working again.

Help with sound issue

Hope somebody can help please? My Zuk Z2 Pro has lost the earpiece sound when on a phone call. People can hear me, but I cannot hear them. I am sure its a software problem but not sure how to permanently fix it.
I ran a manual engineering test by typing *#*#1111#*#* and checked the speaker and the microphone in settings, they are fine. However, the ‘Rec’ setting wont play any sound to the earpiece.
I have read its a known issue and installing the app mswitch (keycut) worked,but it didnt. I then read about switching off "OK Google", well on a Zuk this is not easy to find, so am not even sure I was able to disable this app.
EDIT: After more investigation I have found that when I turn the voice volume up in ringer settings it does nothing, which I think may be the speaker itself. My wife has the same phone and hers works normally. There are three ringer volumes, and the middle one does nothing but I know it did yesterday
I then tried another app called "Soundabout". This worked and allowed the Rec setting in the engineering side of the phone to play a sound, like an increasing oscillalation of sound. I then restarted the phone and it worked, but not permanently. The app doesn't seem to stay working.
However, when I made a phone call the earpiece speaker still didnt work. I could not hear anybody but they could hear me.
However, it does work when headphones are plugged in.
Does anyone know if a factory reset of the software would help as I am stuck and desperate for help. It just suddenly stopped working yesterday, so am puzzled as to why. The phone is just less than 12 months old, so not particular aged and it has always been in a case and well looked after. Its running stock Android 6 with the ZUI overlay from Zuk, so no changes made to it.

I have de same problem. Two months ago the speakers decreased the volume and microphone does not work properly.
I replaced the usb + mic piece, but the problem remains the same. Now, I have ordered speakers piece, but I guess the problem will continue.
The only thing I can think is the origin of the issue could be the bluetooth earphones that in some way had changed the sound configuration.

Try to qfil ZUI 1.9, if that does ot help then its hardware problem most likely.

Finally I have found the origin of the problem. It was in the dust filters of the phone. I used an special liquid for the screen protector. Some of this liquid goes to the filters. I have cleaned this filter with a brush teeth.
It is silly and I feel dumb.

Simple fix
Please do not feel dumb or stupid as this is something we don't think about.
The problem is due to dust and fabric accumulation. I just had this problem.
The fix is simple.
Use something soft to bang your receiver. In my case i used the tip of my finger. You want to the bang to be good but not to break the glass. My finger hurts a bit so I think a small rubber hammer will do the job.
Hope this helps.

Clean earpiece protector
Hi, I had the same issue and after trying all software tweaks with no success, what I have done is use a toothbrush to clean the tiny holes from the earpiece protector. I pushed some brush bristles gently through the holes and... it worked!!!
Hope it helps.
