Mic muted when using speakerphone or confrence calling - Galaxy Note 4 Q&A, Help & Troubleshooting

I've narrowed this down to possibly a hardware issue since I've gone from stock 4.4.4 rom, to custom firekat rom, to now stock lolipop and the result is the same.
When using speaker phone, or conference calling (such as skype), my microphone is completely muted. To my understanding and according to this link, The note 4 has 3 microphones. The one at the top near the audio jack is the one used when using speaker phone and I believe that one on my phone is broken.
My questions are, has anyone else ran into a similar issue?
Has anyone repaired the top mic on the note 4 and knows exactly what to look for, or what part to order?
Is there a program that can switch default mic as per program, like how you could in windows if you have multiple audio devices running?

Low microphone volume?

Does anyone else have the person they are talking to mention how low you sound to them when speaking on the phone?
It seems like I have a low microphone on my nexus 4, unless the phone is directly in front of my mouth the person can't hear me clearly, I'm thinking it might be hardware but I know with some phones this can be corrected with a custom driver that makes the microphone more receptive
Is there an app or setting that I can use that would disable noise cancellation in case that's what causing my mic to make me sound low?

Actually I have the exact same problem - not sure what we can do to fix it.
If I crank up the volume fully it appears to -sometimes- solve the low audio problem.

if it -sometimes- solves the problem then it might be a software bug. i hope some dev can be notified of this. have you tried a different ROM? if yes, have you notified the dev of the ROM?

Its actually on stock, so I just rooted it, and will try with a different rom shortly.
Same thing here.. Sometimes they hear me, sometimes they don't even during the same call..
I'm starting to think the noise cancellation is playing some tricks.
While driving home this afternoon I was on headset on the freeway, where those I talked to could barely hear me.
Unplugged my headset (klipsch s4 image ii), and sound was good. After a while I plugged headset in again, still bad.
When coming off the freeway I kept the headset on while talking - and all of the sudden it was crystal clear (using the words of the guy I talked to at the time). At the same time I noticed that I had no data (outside even edge coverage), don't know if that is related or not.
Is there some way we could experiment / disable or tweak the noise cancelling?
Ps: I have had the same issues without headset also, so definitely something general software things going on

I had the same setup. I am using the Xylon (stable) 15 ROM for several days now, and SO FAR I think the microphone reception is better. I haven't heard complaint from the person I speak to on the regular. *cross fingers* hope it's 'fixed' in some way.

That's exactly how my phone was as well. I would be on one call for a while and all of a sudden out of nowhere the person I'm speaking to says I sound like I'm speaking across a room and I'm like 'wtf happened? I haven't changed positions since I started talking to you!'
I did a little testing with the person I was speaking to as well, to test the microphone receptiveness and the mic seems to pickup my voice better, I wasn't speaking directly into the mic and they said they heard me fine.

I have a sneaking suspicion It might have to do with the noise cancelation as well, I think on paper whoever designed that feature on the phone thought it would be cool but it doesn't seem to be panning out too well. I've read somewhere on this forum about how to increase microphone volume and cancel the noise cancellation using the Terminal Emulator app and/or the phone's dial codes (#*#*some sumbers*#*#).
I have the same earphones (no mic attached) and I have similar experience but I haven't taken note of it like you have since 95% of the time I have my headphones in the phone.
I also want to mention a little trick that I think seems to work when on calls. Whenever I turn the phone over, screen facing opposite of me, I hear less complaints of me sounding too low to the other person. Maybe it's doning something... i dont know.
Same issue - with headset only though
I have the same issue, people really struggle to hear me on conference calls (which I spend a lot of time on), so I have to hold the mic in front of my mouth to speak which gives awful sound quality. I don't have this issue when not using a headset (phone mic works fine).
Nexus 4 + Klipsch s4a = really quiet mic, people can't hear me at all.
Nexus 4 = No problem, phone mic works.
Note - music playback is fine, no issues there.
My klipsch headphones worked fine on my GNex, no issues, so I don't think it is a problem with them. It has been an issue from the moment I switched to a Nexus 4. Have also tried other headset (samsung one that came with Gnex) - and have the same issue of sounding very quiet on the headset mic.
I did wonder if it was an OMTP vs CTIA issue, but the button on my headset works fine to answer/hangup/skip tracks/open voice search etc. so I don't think it is that.
I also tested with another Nexus 4 handset using Soundmeter and got very similar results on both handsets, suggesting it isn't a handset issue (though not a very scientific test).
Does anyone have any ideas?
Just In Phone Calls?
Hi Folks,
Is this mic issue just related to phone calls?
I'm using the latest CM10.1 nightly build and my mic is useless for phone calls.
However, Google's voice search works just fine and if I record a video my voice is recorded just fine.
I could be wrong but I suspect the Nexus4 can not use the phone jack for incoming audio.
In my opinion when one plugs a headset into the audio jack the Nexus4 camera microphone
becomes activated, not the headset one. And the Nexus4 cam mic is really bad.
Again, I might be completely wrong. (I hope)

OMG you have it reversed. What a mess!
I have yet to see Google Search understand anything I say and video sound is horrible. Call audio is great.
Hi guys - I am on stock android - same issue on 4.2.2 as on 4.2.1.
This isn't just related to phone calls, same issue on google search. I tested headset mic pickup volume when speaking normally with Soundmeter - around 35-40dB (what it calls a quiet whisper at 3ft to quiet residential area, Park).
I also tried moving the headset mic closer and further away from my mouth with the phone in the same position - with the headset mic virtually touching my lips it went to about 60 dB (normal conversation at 3ft) - so it does seem to be related to the headset mic. I can only guess it is either a dodgy connection in the handset or some noise cancelling functionality that is cancelling out my voice!
Any ideas or thoughts greatly appreciated

Darn it!
I knew I was an outlier.
No way I'm getting a fix for my issue then
Anyone figure out a fix? I'm having similar issues with my microphone.
Hooked as bluetooth device in my vehicle, other end hears me fine.
On phone call using speaker phone, other end hears me fine.
On phone call WITHOUT speaker phone, other end cannot hear me at all.
Using a sound recording app to record voice, playback of the recording I can hear my voice faintly if I was YELLING during the recording.
Shazam/Soundhound apps do not work.
I am rooted on rasbeanjelly/trinity kernel. I have to say this issue started a few days ago when I have done no changes to the phone. Already running the rom/kernel for weeks.
I've tried flashing back to stock rom/kernel and the same problems persist.
Any ideas?

Just an update, I unrooted and reverted back to stock and the problem went away, so it was defnitely a software issue. Will be trying other roms/radios/kernels and see if the problem comes back.
I was on rasbeanjelly 4.2.2/trinity
akira112, did you get any success with your experiments?
Guys, is there any progress / comments regarding this issue?.. Microphone itself works fine when recording the voice with some app, but during the voice calls it is the mess...
My Nexus 4 is two months old and is being returned to Google due to the microphone constantly cutting me out on calls to business clients. I've tried every trick from sound apps to custom roms. No joy. I'm hoping my replacement doesn't have the same problem (although given the sheer number of postings on this issue, I suspect a Nexus 4 design flaw)...
Hello
Is there any solution to low microphone volume problem?
I have been using my N4 for a week and some people complain about my voice's volume. There was no such problem with my previous phone (Defy). There is no difference whether I use phone's mic or bluetooth headset.
My Nexus runs CM10.1 with Franco kernel.
Also keen for a solution
I just returned my first N4 due to the speakerphone cutting out after a minute or two, and getting stuck in non-speakerphone mode.
The replacement seems to not have this issue, which is nice.
But now people are telling me they can hardly hear me. It happens both with normal mode and speakerphone mode.
Ridiculous.
I will be calling Google tomorrow to see what they say, but I am not going to hold my breath for a decent response. Judging by the number of people reporting this issue online, it's not something Google has a solution for.
If anyone figures this out, I'd love to hear about it.
Have sent mine for repair because of this problem. People told they could not here me well.

I have the same issue, couldn't fix it but what I noted was that any mic gain adjustments I made only applied to the phone's mic not the headset mic. That means that there is something else that modifies the headset mic, but I do not know.

Microphone does not work only in speakerphone mode

Hi all,
I just got a Nexus 4 recently and I've been racking my brain with what on earth is happening with the microphone.
The problem is that the microphone WORKS PERFECTLY when doing a google search, voice call in normal mode, or voice recording. It does not work at all if I enable the speakerphone during a voice call. This seems to be exactly the opposite problem that others are having with the Nexus 4. I can still hear the person in the call but when I talk, they can't hear me. Not even white noise, just total and utter silence.
I have tried 2 flex cables (trying replaced the initial one whose microphone didn't work at all, at the time I had CM11) and tried flashing everything (baseband, recovery, system) to stock 4.2.2, tested it with no luck. I then flashed everything with the latest version 4.4 off google's developer section and tested with the same issues. I've tried factory resets, unplugging the headphones, and also soundabout and nothing resolves the issue.
When I look at the flex cable and the phone housing, it seems to me that there is only one microphone on the bottom. On the top, there is the noise canceling mic, but I don't think this has anything to do with the speakerphone. Am I wrong? Does anyone have any thoughts or suggestions? I don't know whether this is a hardware problem or some low level software issue.
UPDATE:
I noticed something super strange. If I plug a headphones w/ a mic into the headphone jack, I can actually hear very loudly and in great detail the friction from my fingers moving up and down anywhere the case of the phone, and if I tap on the body of the phone (anywhere, even near the USB port on the bottom) it's like stuffing paper into your ear canals. I can still hear the person on the other end fine, and they can also hear just as clear and loud when I touch the phone body. This phone is a science experiment now. The closer I move my fingers to the bottom of the phone near the mic, the louder it gets.
've tried everything. You also changed the Kernel, I do not know ... Maybe it's a problem RADIO, but I doubt it.
Eventually contact Google support
Typical factory problem....when i bought my Nexus 4 (S/N shows production date is October 2013 so its the newer batch with little nipples and camera lens offset fix) the microphone was dead and i could've only talk through headphones and speakerphone....took it to the repair shop and everything works now. Don't know what they replaced, maybe it wasnt the microphone.

Primary mic broken, is it possible to redirect to secondary mic?

Hi all,
I am having problems with calling since i bought my n9005 4 years back, people did not hear me speak on the other side, but when i put the phone in speaker mode the sound was just fine on receiver side.
Using different roms from stock to CM13 and miui nothing software related seemed to be the problem (tried all the things that i could find on the net and in settings).
Anyway, so I always been calling on speaker or using my huawei watch.
Now after all this time i thought lets fix it, and bought a new USB / Mic unit which i installed without success.
Since on speaker calls still works great, normal calls only cracking sound, i thought maybe its possible to redirect thru software to secondary mic on top of phone which i believe gets activated when talk on speaker phone?
Thanks in advance.

Mic problems

Odd problem I've had since starting to use Exodus 6... I don't know if it's a ROM problem, or something more general, as this is the first MM ROM i've used.
Device: D850
Currently running 20160419 nightly
(Clean flashed 20160416, but the factory reset didn't resolve the problem)
stock kernel.
The problem is that whenever i switch to speakerphone while on a call, the mic mutes itself and the person at the other end can't hear me. Turning the speaker off reenables the mic. I've recently noticed that the same occurs when i have the phone plugged in to my car audio through the 3.5mm jack. Sound outputs, but the mic is muted, so hands-free calling doesn't work, "OK Google" doesn't, voice-to-text for sending messages stops working, etc.
Anyone else run into this? Is there a fix? A way to start tracking down the problem, perhaps?
I had the same issue on cyanogen 13 with all the recent nightlies after some point in February. Could never narrow it down. I ditched cyanogen since and went back to stock rooted and I have no issues. I also had issues with speaker volume being extremely low.

Mic not working during calls (maybe broken mic) How can I switch mic via mixer_paths?

Hi there everybody. First time posting anything in any forums. Please excuse any irregularities that I may show (deviating from the norms and such).
ISSUE BACKGROUND
So I recently bought a LeEco Le Pro 3 (LEX727) second hand and I've run into an issue with the microphone during calling. I can hear the person calling fine, but the caller cannot hear me. I have checked that it is not a sim issue as I've tested call with two different sims (one local and one international sim). Currently it is running on LineageOS version 15.1-20180312-NIGHTLY-zl1. It is currently rooted via Magisk.
In system/etc/usf/form_factor_mtp.cfg I found out that there are two mics:
- top right mic
- bottom 90 degree mic.
I confirmed the top right mic is working as Google Now and recording apps picks up my voice. Using the MicTester app, I also confirmed it is indeed the top mic is functioning fine as the sound wave increases in amplitude as I input sound closer and closer to the top mic (as opposed to the bottom one).
I feel it is not a software issue as I have flashed various roms to the device, resulting with the same issue. Roms I have flashed includes:
- AICP (Oreo)
- Stock EUI
- Resurrection (Oreo)
- LineageOS (Oreo)
- Lineage OS (Nougat)*
*note: the phone came with LineageOS in Nougat. Same mic issue
Flashes were attempted with factory reset only and with complete wipe of internal storage (this was the latest attempt)
Also attempted to use MicFix module for Magisk. Still no mic
Also tried muting/unmuting during calls. Still no mic.
Also tried toggling loudspeaker on and off. Still no mic.
Hence, I feel that it is a hardware issue. To strengthen that opinion, there is a one solitary dent on the phone, near where the mic would be. Could be a completely busted mic or disconnected mic.
Also calls works fine via a connected wired earphone with inline mic.
CURRENT PURSUED SOLUTION
To remedy this issue, I wanted to reroute the mic paths for calls. Instead of using the bottom mic, I want to use the top mic instead. So could I get some assist in editing the mixer_paths.xml file of this phone to achieve that?
I found there are a few file with the name mixer_paths
system/etc/usf/mixer/mixer_paths_mtp.xml
System/vendor/etc/mixer_paths_tasha.xml
System/vendor/etc/sound_trigger_mixer_paths.xml
System/vendor/etc/sound_trigger_mixer_paths_wcd9330.xml
There is also this file:
System/vendor/etc/audio_tuning_mixer_tasha.txt
Can anyone help me figure this out with me?
Also, if there is a better way to solve this or that maybe the direction of editing mixer_paths is not quite right please do tell.
Note: I am not adept at codes. I have done a semester of matlab and c++ and that's it. Not really code savvy.
Any assist is very appreciated. Have been troubleshooting this issue for a few days now. Can't seem to be able to solve this
Hmm... I don't know if you'll get the help you need here. You should also try posting to reddit.com/r/AndroidDev, or maybe the general XDA Q&A forum?
What you might find easier to do is just replace the mic entirely. The mic is located at the bottom of the phone, on the charging port module itself. Replacements are available on AliExpress, but they might be missing some features(?). A few other users have the same problem as you. I encourage you to read through this sub-forum.

I'll try with ur suggestion to post this elsewhere. I'd rather not replace the microphone just yet because I'd like to try a non-open-my-phone-apart solution. Not the most dexterous of hands.
use a headphone/bluetooth mic till u fix it
I have a different device but the same issue. Main mic is not good, gives nothing but hisses.
Tried using RuleBot(info.kfsoft.autotask) from play store to automatically enable loudspeaker (which forces microphone to switch) when there's a call. I will update later if it works.
