Has anyone dealt with a dead mic ?
One day out of the blue on 4.4 mic stoped working.
Installed L 5.1. beta 3 and the mic still seems dead (Calls and Google voice) HOWEVER in sound recorder the mic works (picking every single sound) ...
Further more installed the HiQ Mp3 recorder which apparently can use front and or back mic and it works in all configs .(front back and stereo)
Tried different values via engeenering mode with no luck ....
****** Apologies to all this post was misplaced in this forum *********
I guess I should replace the charging board alltogether however I am puzled that the recordings come out clean ......
Anyone with a similar experience ??
(btw sound on wired headset is fine ... bluetooth sound is broken I think due to beta since the bt headset and speaker I tried didnt work)
Phone is Jiauy S3A
Ok Results
The issue was a dead mic (low mic) or rather a near dead mic.
Replacing the mic (on the same board ) resolves the issue (note that you can use third party mics i used asamsung one)
Best test to realise where is the fault
Open the camera recorder and start recording
Close the top mic hole with your finger, start talking in the lower mic and in the end gently (very gently) blow towards the hole.
Repeat on the top hole with the lower hole closed
After that listen to the video
If there is a problem with a mic the voice might be heard but the blow will be almost inaudiable in the problematic mic.
I have exactly the same problem - mic works fine on sound recorder and on the video camera, but Google Voice Search and using the phone does not (I've tried your blow test and it's all fine). This surely cannot be a hardware fault, can it ?
I've tried updating to LL5.1 beta3, but same problem. I've fiddled with the audio settings in the engineering menu, using a variety of values, and turned off the noise reduction without any success.
Any ideas ?

Click to expand...
Click to collapse
Google voice was the main indicator that the mic was bad ....
Do the blow test again and try as "gentle" as possible and then compare the results, if the uper mic is louder then then mic is dead or nearly dead.
Most probable that you ll need to change your mic
Thanks for your help - can you provide a link to the replacement mic you used (or did you use one from an old phone) - and is it easy to replace ?
Unfortunately I did go to a service shop for the repair, so I dont have a model number, all I know is that he proposed two different types, one was a noname and the other one was made by samsung (so my guess is that any samsung service center can sell you one) .
The process took about half an hour, unsoldering the old mic and soldering the new and the cost was 10 euros ( around 11 USD)
Sorry I couldnt be any more helpfull on that.
I found that, after video recording with stock camera app, main mic stop working for calls. only upper mic working. you can test it with 2 phones in both hands. but I was find simple solution: many people holding phone when taking pictures so the controls are on right side. but if you turn you phone so the shutter button will be on left side, after video recording, main mic still working!!! btw. if you like to take a shoot with control button on right side, just after you finished, turn your phone for 180° and make one more shoot, just to save your main mic for calls. no reboot needed after this action. tested on many roms, KK or LP, happend with all roms and stock camera. so problem is with stock camera app and sensor that give the information to phone to disable main mic.
Well mine was definitely a hardware fault - got a replacement lower board (USB/mic/speakers) and replaced it myself - all good again.
I think i've got the answer. The lower mic is broken for some of us. When we got to the camera app and take a video and turn the phone around it will indeed change the mic and then will use the upper one (still working) in future calls. This is why you can then be heard after when you call someone, but you'll be using the upper mic and the lower mic is still broken. Once your reboot you have to redo this. I'd like to buy a new board (usb + mic) but we cannot find any on internet anymore. Except some sellers on Ebay who are selling it from 150 dollars to 900 dollars (no joke). I guess i don't have much solution except doing that trick and use the upper mic and then try not to reboot the phone.
As many of you already know when using a speakerphone only the bottom speaker is working. Is there anyway to enable it to have both working? Maybe something kinda like this http://forum.xda-developers.com/nexus-5x/themes-apps/mod-surround-sound-testers-t3252659?
as far i know, this is not possible (yet). i'd love it if someone could make this happen.
Dual speakers
What do you mean by bottom speaker only work on Nexus 6p? Mine work on both top and bottom speakers. Do you have a different device or model?
dual speakers work... just not for phone calls (speaker phone)
I was so disapointed when I found out that only one speakerphone was enable during phone calls. I use a lot the speakerphone and that was the main reason I bought a 6P, to use both speakers, especially when driving.
Does anyone know how to enable both speakerphones?
Voltage outputs can be adjusted to make the volume louder during phone calls from the handset and speaker phone from the mixer paths file. It might be possible to change something in there to allow using both speakers during also.
Since you can you make use of both speakers with videos music and gaming , there should a way to allow them during calls.
I have an microphone- issue with my Note 4.
It has 3 Microphones. The Mic on To(rear mic) works fine its active when Recording Videos and phonecalls over LoudSpeaker but the two mics on the bottom (front mics) have some issue and are really quiet.
I have to scream when i do normal phonecalls and also in whatsapp nobody understands my voice.
First i thought it would be some dirt in the mics,but i cleaned them and the issue is still there. i know that i can change the Microphone Sensibility in the mixer_paths.xml, i just dont know the details and values.
i also tested with" Hi-Q MP3 Recorde"r some settings. i can increase there the front mics on the bottom 20db+ and then the sound is fine but its just in the Voicerecord-program and not in the system.
So its not a real hardwareproblem that forces me to change the mic or the phone.
So i need to know which values i have to change in the mixer_paths.xml and how to do it step by step and i know that some more people have that problem.
i hope for your help and i know that this board has some real good programmer and experts.

Just I observed that while the earphones are connected and playing and music/video, sound is coming from speaker too, and it is loud. Person next to me can hear it clearly. "Not with calls."
Any one facing this issue ?
And please provide solution.
Running stock ,latest update with no root and camera API is enabled.
Try changing ur earphone........and make sure u r putting the earphone jack inside properly...
I tried different earphones like MI, Oppo, Onemore, boat, but same result. But while calling it doesn't show that kind of behaviour only Music and video in-storage and online show the problem.
