Main MIC not working or inaudible FIX - Nexus 4 General

Anyone out there having issues with your mic "not working"
Well I have.
I have tried different fixes found on the net to no avail.
Soundabout app which switches where your audio is routed and such. Also fixes your phone if its "stuck " in headset mode. This worked for like 1 day then it went back to the caller not hearing me.
I tried easy voice recorder pro that didnt work.
I tried faux kernel and his app to boost the mic gain..... no go there either.
Some even said 4.3 update fixed... not for me.
I even fastbooted the .img Still a no go.
I could speak directly into the mic and the other end could barely hear me. If i held the phone normal ...nada.
If i put the call on speaker the top mic switched in and all was great....
I just about ordered myself a replacement mic and charger port board when I decided to take a look at the build prop.
I found an entry that had mic in it so I googled that entry and came up with Noise Cancelation. hmmmm
Here is the build prop....
"persist.audio.handset.mic.type"
Using ROM toolbox I changed its values from "digital" to "analog" rebooted and voila Callers could hear me again.
I'm only going on one day with no issues.
I've been banging my head, searching, and reading to solve the issue. I saw where several people had to RMA their new devices one dude had 4 replacements and was still experiencing the issue.
For everyone experiencing this issue I hope it helps

Yes actually it is. I even put it back to digital just to see and it stopped. Put it back to analog and working again. Sorry..

Can you please demonstrate how you did this exactly. I'm really don't want to have to import parts.

Microphone Issue, Cannot hear me or Muffled

Hello guys, I have recently purchased HTC one, and flashed Cyanogenmod 10.1 and teamseven AOSP kernel on it. I noticed there is issue with microphone during calls. Distand end cannot hear me or it sounds extremely low/muffled, but when I put it on speaker phone, issue goes away. Also after few min it sometimes randomly decides to work. I have tried to flash Android Revolution 22.1 (4.3) to see if the issue will go away, but it is still persisting. I would appreciate any help I can get, thank you
Just a quick update, I did more research on this issue and it seems like a common issue with newer HTC One models. Noise Cancellation seems to be the problem, since talking to the phone at certain angle seems to might the issue go away. I even tried restoring my phone to the stock, and even tried the disable noise cancellation fix that is around in the forums, but it did not make the issue go away completely. This is my second HTC One in 3 days, first one had a nasty dead pixel, and now microphone issue. I will take it back to AT&T store and get it replaced again. I'm not sure what is going on with the quality of the phone on newer models, since I've had the Developer's Edition and AT&T model on launch day and both were perfectly fine. Is anyone here having the same issue and found a fix for it?
Another quick update, I seem to have fixed the issue by SCREAMING into the bottom microphone hole during call for a minute to see if I can fix the volume, and it might be hard to believe but issue has gone away. I read this in another thread about the microphone issue, someone posted by screaming into the hole, you are adjusting the volume gain and fixing the issue. I recommend trying it if you are having the same problem, since I've literally tried everything else and this fixed it for me.
I have similar issue. For more I noticed random disconnections during call.
it worked !!!
It worked....

your speaker works where you can hear the call but if you talk into it the person on the other end cannot hear you.
It has been broken in AOSP for quite some time now. CM 10.2 STABLE has the same issue.
The only working rom with speakerphone is GPE/sense based ones.

[Q] Extremely low in call volume.

My HTC One has extremely low in call volume from the mic. I can hear the person I am calling or who called me fine but they can't hear me or barely able to hear me. I downloaded a sound recorder app and when I talk into the mic in that app it plays back at a reasonable volume. Would a different radio file fix this problem?
I had this issue with my One X for awhile, come to find out, there was lint stuffed up in the mic hole.. Check that first.

I am having the same problem. when I am in call, if i switch to speaker phone it instantly becomes loud clear. I am going to RUU back to stock GPE or stock Sense to see if it fixes the problem.
Ill report back to you if it does.

I have the same problem with my replacement phone. I'm sending it back to TMO for another. From what I've read it seems like a hardware issue related to the noise cancelling microphone.

My nexus 5 arrives tomorrow. Once I have that in hand, I am going to fully wipe my HTC One, RUU back to stock and S ON the phone to be sent back to HTC for a replacement. I will test the microphone before sending it back to see if the full RUU fixes it but I doubt it will.
I flashed several diff firmwares, h boots, kernels, roms etc on the phone and none of them had an effect of the mic. The microphone problem appeared out of no where when I was running a rom and kernel combination that previously had no issues. In other words, I changed nothing and the problem arose. No combination of software changes yielded any improvement in my limited testing. I am quite sure this is not a solvable problem as it is hardware related and that you should likely send your phone in for a replacement.

Mic only works when switched to speakerphone?

Weird issue here, when im in a call no one can hear me. They can only hear me fine when I press the speakerphone button. I tried using voice recorder as well and no audio recorded. I know there are two mics, but do they switch when you turn on speakerphone? So maybe one mic is blown?
Current setup
Latest firmware and radio, BadBoys 4.4.2 ROM,S-OFF

Adjacent to the USB input on the bottom of the phone will be the microphone. Try gently clearing it out with a safety pin to see if there's any gunk in there.
There's been known issues with the built in noise cancellation interferring with the bottom microphone. Try covering the back mic (the one that's top right of the camera) and talk into the bottom mic to see if you can hear anything. I don't believe there is a known fix yet for this issue for the Sprint HTC One if you have noise cancellation problems.
Viper ROM 5.7 has a setting to disable noise suppression, but that didn't work for me. I hear there's two noise cancellations. One built into Android and another for HTC. The Viper ROM setting disables only the HTC setting, not the android one.
I had this issue too and had to do a small "song and dance" with an HTC rep to trouble shoot the phone. They eventually agreed with my conclusion that the phone was broken. They sent me a replacement since I was under factory warranty and I haven't had any problems since. Best to call HTC and put in a trouble ticket.
Yeah might be a combination of both, just weird that it works only when I hit the speakerphone button while in a call. Thanks
I have had that issue sporadically on my one since the latest firmware update. Happens for no reason occasionally.Never did it with old firmware. When I have time I want to try reverting to older firmware to see if the issue is resolved.
I have had this problem for months. Speakerpho e works because it uses a separate Mic on the back of the phone on top.
The problem Mic is on the phone bottom near the charging port. Today I called my house pho e and screamed into the bottom Mic for two minutes and it's alive again for the fitst time in months!
How long I dunno worth a shot though since using speaker gets annoying.

Thanks that's what I need info on. I figured the speakerphone was the one on the back. oh well, i'll have to manage until April I guess.

No loudspeaker sound

I was on CM12.1 earlier this morning. Suddenly I realised that my earpiece is not working while on calls. Neither did the screen turned black in effect of proximity sensor while on call. So I right away flashed stock to check whether its a hardware or software issue.
Digging more into the problem I could make out that its not the earpiece that is damaged but its the phone that thinks the headphone is still connected. I used an app called SoundAbout to check the media output. And it was confirmed that headphones is used for media output. Then I checked playing a song, it didnt through loudspeaker which also confirms that phone is detecting the headphone is plugged in while it is not.
Below I upload the screenshot of that app called SoundAbout which I used to find the problem. Sorry for such a long post.
Any help, suggestion, or any strange or extraordinary experience that could help?
Any help is appreciated!!!!!!!!!!!

Well if you are using SoundAbout why don't you then select where you want the sound to come out from? Isn't that the whole point of that app?
Also dunno about your proximity sensor issue but my phone suffers from similar ear piece issues as well and the issue crops up sporadically so I am still not sure sure its completely a hardware issue. I spent months looking for a solution but was finally about to hand it in for repairs when I the came upon the strangest solution somewhere. Here's what I do when this happens -
Plug my headphones in
Make a call
When you can hear anything in the headphones (call being connected, recipient's voice...heck just dial a non existent no. so you can hear the operator say it doesnt exist, any sound at all) , pull the headphones out and the sound comes out the earpiece.
I know it sounds silly but it works for me. It might not work the first time but after a couple of tries, it always does. Till date the only workaround I have found to this issue albeit a temporary one. Lasts me a few weeks before it happens again. Rinse and repeat.
One of these days I am gonna bite the bullet and hand it in for repairs. Remember reading someplace that this could be because some chip or something that supposed to switch sound depending on the task fails to do so though I am talking from memory here and this might be completely inaccurate.

i saw some users have the same problem actually ....try to plug and unplug it several times and see what happens
and clean your headphone input plug then reboot ....if any of that didn't help then repair it
None of the above method worked for me. I will send it for repair very soon. Till then I will use the app to manually route audio to loudspeaker.

Do let me know what the diagnosis is and the cost of repairs as well. If is a similar issue and doesn't cost the earth, I might repair mine too. Thanks.

Actually the issue is called stuck in headphone mode. If you google it there are a number of methods to solve it. One of those you could try out is http://forums.webosnation.com/webos...37-stuck-headset-mode-permanent-easy-fix.html
Go to a hardware store, pick up a tube of graphite powder for around $3.
1) Gently squeeze a couple puffs of graphite powder into headset jack.
2) Turn phone upside down to let excess fall out.
3) Grab a pair of headphones and insert/remove them several times.
4) Enjoy your new, permanently fixed phone.
Im planning to try this out. Even u can!!!!!!!!!
I will report soon

Lol graphite powder?! Will pencil shavings do?
Well I suppose I now know why the method I posted was working for me. Was doing the same thing minus the graphite powder. Sticking the headphones in was causing the problem as well as solving it too. Mental.
Dude kindly gimme a sitrep as soon as you are done

Haha...awesome Time for my SP to have a graphite powdering of it's own I guess
Since my ear piece is working now, i won't be and to tell the difference really but at least now i have a solution. I am gonna try it nevertheless. Thanks a lot man. This has been a long standing problem.

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.

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.
