[Q] Does Custom ROMs and Custom Kernels have Mic problem

Hello Everyone,
I have recently purchased a bright red Nexus 5 32GB, and found that there is a problem with mic.
I have to speak loudly or repeat my words so that the other person on call will be able to hear me.
I have gone through this thread and found that am not the only person with this problem and users have also raised the same in this google group.
Users are stating that they have RMA'd the phone but the problem still exists.
I too have done testing with sound recorder apps and they all seem to record my voice properly.
I want to find out if this problem is only in the stock ROM or does it also effect custom ROMs and custom kernels.
so, anyone using custom ROM or kernel can please check and update us if the mic is working properly in your phone, can the other person hear you clearly. can you check any voice recording app and google keep and confirm if the voice recordings are of same volume and clarity.
Thank You.

It exists for everyone and there is no known fix as yet

Ah, so it's not my network then... lots of people saying I'm either very quiet or garbled when I call them. I wonder if the noise cancelling needs tweaking? Could be that it's partially cancelling our voices.

It is indeed believed to be a problem with the noise cancellation algorithm.
some rooted users change a value in their build.prop to "turn it off" but I cannot say for sure it works for everyone.
Waiting for a fix.

i believe its because of noise cancellation.
to check it, i tried using ' ok google ' on my home screen. it wasn't picking up my voice.
then i've closed the secondary mic on top with my finger and said ' ok google ' and it works as it should.
this is working even with my phone calls.

[Q] big Call volume issue

I purchased my OPO two months ago and it was fine even in the call section. I love this phone but recently i have been facing a problem. When i place a call or recieve one then the person om the reciever's end is not able to hear my voice clearly. It's too low and sometimes my voice is also distorted. I have tried flashing various radio zip and also updated my phone to 05q, i came back to 44s and still i am having the same problem. I Googled it and i saw that some of the users are also having the same problem. When i reset my phone this problem gets solved but as soon as i download some apps.. I again start facing the same problem. It is quite frustrating.. Other than this.. This phone is too good. Please guys can u help me. Is there a way i can get rid of this?

hmm no replies. anyways i fixed this .. it seems it is really a big issue for oneplus one, they call it "robotic voice" and the fix is really simple. disable the "ok google" feature and delete your voice recording on it as well.

Problems with outgoing call quality

Recently I've been having a lot of intermittent issues with the quality of the calls on my oneplus one. People keep telling me they can't hear me well or they hear me voice all chopped up.
I hear people on the other side of the line flawlessly.
This seems to happen at no particular location. Even though at work my reception is really bad it also seems to happen while I'm driving.
For what it's worth, I can't recall one time that def told me one time when wifi but I wouldn't bet on this.
Currently running CM 12.1 nightly 20150504. Stock Kernel
Had anybody experienced this and had been able to solve it? Is pretty frustrating.

I am also facing same problem if any has solution
kindly help

Yes same problem for me. After reboot everything goes well for some time

I agree with all u. Even I am facing same issue. But Try ColorOS, MIUI, CM11. These ROMs gave me good network.
Problem is those are KK OS and most of the cases I am facing Google Services Keep Awake.
In LL, try Exodus, AICP. These 2 was good but not like the OS I have mentioned at top.

have you guys checked audio effects. See what have you checked off because I read that may be an issue. I also had a friend with the same problem and that solved it for him. He was on stock

I had the same problem following replacing a broken screen. Thought it was something I had done replacing the screen. The phone upgraded to 12.1-YOG4PAS1NO when I turned it on. Phone calls to some people were garbled at there end, call reception was good at my end. OK google worked, using the audio recorder App worked perfectly. I went to mobile network setting and changed preferred network type to LTE (recommend) and clear call quality has returned for three numbers that I tested it on. Not sure why that network type had changed. Not sure if this is just a coincidence. Will test further during the weekend.

I found somewhere that suggested it was something wrong with the noise cancelation and of you put your finger over the microphone on the back by the camera it should help. Haven't tried covering the mic yet, but noticed that if I'm somewhere a little louder then I don't have issues and when I am somewhere quiet I tend to get complaints, which leads me to believe it is something to do with the noise cancelation

Also just found where it suggests disabling "OK Google" from any screen feature. Just disabled it and waiting for someone to call me

I, I desactivated OK google on every screen; after that the sound was perfect on all my outgoing calls

"Ok Google" deactivation from every screen solved the problem for me. Check this out - http://forums.androidcentral.com/lg-g3/504150-call-quality-has-suddenly-tanked-2.html this is where I got the clue to do this.

I had the same problem and indeed this seem to have solved it! So far so good...

I used this fix and according to a few people they have no issues hearing me anymore. And I also still have Google Now on all screens, so that's nice.

OPO mic troubleshooting - is there really not a way out?

Hi Guys,
well, the mic issue is not really an unknown to OPO users - I have never experienced such issue, but some time ago my mom let me know she has problems with mic for long time now (she has inherited my OPO), so there I went - looking for an intel regarding this issue.
I have come across some standard fixes for Cyanogen (the last official one by OPO themselves):
- blow out dust/debris from the microphones (done with a vacuum cleaner),
- remove TrueCaller, voice recorder, turn off "Ok google" recogniton (basically not a problem for us, we have Slovak language, thus no support anyway),
- tried other services - like Viber and it worked perfectly!
- tried speaker mode - worked!
So after this I came into the conclusion maybe a drop or something has damaged or something the rear mic for ambient noise suppression (maybe?).
But then I found some info the CnM is the problem itself, so I have just switched to the LineageOS (it is not really a change when I am thinking about it now, well is it?), but this has not helped, still the same problem.
I have found this too and applied too, but, again, no success.
Do you happen to have any other suggestion? How is it possible Viber works? Can be some app such as Viber used as the phone app too?
Thank you, in an advance...and I hope we will come to some conclusions here, I am wasted from all of this...

Just a little search,and look what I found!

Oh, I thought I will get around it without a root, thus why I did not try any of the "must be rooted" approaches. But yes, it is fixed now, however...
This is a very unwanted outcome - the phone has been used for recording band's sessions as well where the mic array was used fully, but now calls, yes, are ok, but the recording quality is horrid - basically it was recording like when you switch a call to the speaker mode, where other microphones were recording too and giving that full-bodied sound, now it is like through a gaming headset with a noise cancellation.
What is this issue caused by, anyway? Is it because of a damage of one of the microphones?

Anyone? The rear mic was really handy for the music recording (full sounding). Is it possible to make it somehow toggleable?

LineageOS 16: Crackling sound with voice messages on S7 (SM-G930F)

Hey,
I recently flashed LOS 16 (coming from LOS 14) in order to hopefully get rid of my crackling recording problem.
The problem unfortunately is still there. I don't know if it's a hardware or software problem.
Phone calls are completely fine, however, the microphone makes a really annoying crackling sound whenever I record voice messages or use any kind of voice recorder on my S7.
Perhaps someone has an idea about what I could do. I already did some research but nothing helped.
Is there a way to disable the onboard microphone and just use a headset whenever I want to record voice msgs or make calls?
I'd appreciate any input.

Ever tried updating your baseband?

Yesterday I flashed the newest Samsung firmware. Voice seemed to work in the stock rom. I then flashed LOS again and the "crackling" in voice recording is back again.
I'm not sure what updating my baseband entails (and I don't know how to do it, actually).
