Very low in call volume - Nexus 6P Q&A, Help & Troubleshooting

I'm going to try to explain this as thoroughly as possible.
So I have been having this issue with every single 7.0 preview and now it has followed me into the actual 7.0 release. My in call speaker phone and regular volume is very low. I have no idea why this is. The headphones sound is fine, playing music through the speakers is fine, it is just whenever I get into a call that the volume drops. It is very hard to hear the other person. The other person can hear me easily, however. This issue never appeared while I was on Marshmallow, only exists on Nougat. I am rooted, so I do have the ability to do whatever root fix exists, although I have tried a few, including editing the mixer paths.xml.
Anyone also have this issue and have a fix or anything related to it? I REALLY don't want to roll back to Marshmallow if I can help it.

Do you have viper4android installed??

I also had this problem but it was only after installing viper4android. I reflashed the system image getting rid of viper and everything went back to normal. There is a conflict somewhere but I haven't figured it out yet.

Weird Audio Issue

I've been having a weird audio issue with my Nexus 7 and was wondering if anyone else was having it. I search before starting this thread and couldn't find anything similar, which leads me to believe the answer is 'no', but thought I would ask anyway.
So my N7 was one of the first to be released. For a couple months I've had no major issues. A little screen lifting, but not enough to make me send it back. Some issues with the screen (what looks like burn in, but goes away) which has been heavily reported, but again, I can live with it. Both of those issues are well known and common, but this one just started up.
Every so often, when my N7 has been sitting idle and in standby mode for a while and I unlock it, I hear a "click" sound from the speaker. It normally makes that sound, but on occasion it sounds weird and clipped. When this happens, I lose audio. The only way to regain it is to either reboot the device, or manually lower the sound to zero, wait a few seconds, and then raise it up again. The latter method usually works, but once in a while I have to do it multiple times before the audio is restored. When the audio stops, it doesn't matter if it's the built in speakers or headphones - nothing.
This problem seems to only occur right after I wake it up. In other words, if I'm using it actively and I have sound, the sound works fine.
Again, this problem only started occurring about a month or so ago, and is only sporadic. At first, I thought it might have something to do with a new app I downloaded, but I eliminated that variable.
It's not a major problem, but it does get annoying every so often.
My N7 is stock firmware with a custom kernel (Motley) and rooted (obviously) with CWM recovery.
The logs don't indicate any issues. And since the audio comes back with me turning it off/on (usually), it seems more like a software issue.
Anyone else experiencing something similar?
Also, when the sound is working properly, it sounds great. No static or distortion or anything like that.
I have the same problem, at first i thought it was because of the kernels so i switch kernels from stock to motley then now i am on clemsyn. I do not know whether it is a software or hardware problem because my speakers sound perfectly alright, except the symptoms which you described.
My case is then sometimes when i unlock it, the normal click sound on unlock might be distorted and then for a period of time there will be no sound. The quick way to solve it is to plug in a headphone and then pull it back out, this will get the sound back immediately OR i can just wait for a while and the sound will be back. Again because of the speaker not having any other distortion during normal music playback, this might actually be a software problem, but it seems not many pple have documented this behaviour so hardware problem is also likely.

I think it could be a hardware defect with ours. Since you are the only other person to report the exact same symptoms, it seems to be rare. In my case, it occasionally happens even with the headphones in, so I don't think it's a speaker issue - more likely a sound card problem. If it was software, I think it would be much more commonly reported. Oh well.... Weird that it only started happening about a month or two after I owned it.
juz an update on my nexus 7 audio issue, i recently just flash franco kernel and the audio issue seemed to go away completely. i amnot sure whether its the overclocking or the undervolting that caused the problem but i am glad it is gone. Juz FYI.
I have a similar situation where the sound stops working randomly. It's rare, but maybe once a day. The volume buttons remain high but there is no sound. I have to reboot for the sound to come back. I am on Kaos Droid 3.8 Beta, with the Clemsyn Elite Battery Saving kernel.

Microphone issue ( Maybe Noise Cancelling)

Hello guys, i'm facing a very annoying issue, since i updated zenfone 5 to lollipop, my microphone randomly and at most time, the microphone doesn't work, during a call the other side can't hear me, but if i put in speaker mode, the microphone works well, also in recorded videos or audio, there's no sound, curiously, if i speak near the upper mic hole, the other side can hear me with a low quality voice. In nexus 5 there's a similar problem, and if you change the "persist.audio.fluence.voicecall=" to true in build.prop the problem is solved, so I guess the issue is in microphone noise cancelling. I want to know if there's a way to solve this, where I can disable the noise cancelling, i searched in build.prop but i didn't find a option related to mic/noise canceling.
P.S. I already change the firmware from stock lollipop to shell rom 5.0 and did a full wipe and the problem persist.

HI,
maybe you fixed you problem yet (I'm sure you did after more than a year, but for other people having that problem).
Open claculator and type .12345+=
Go to BoardMic_Test
Make loud background noise for eg. from PC select one under youtube for phrase "industrial sounds 10 hrs"
Tap Start and talk to you phone.
Stop noise and listen results.
You may repeat procedure several times as results will satisfy you.
Try the same without noise, should be OK.
It works for me, no mic replacement, no software upgrade, no restarts, no restore factory defaults

Buzzing Sound

Hi!
A couple of months after I bought zuk z1, the sound just disappeared for notifications and when music was played through speaker, the speaker would make buzzing noise and it would fluctuate. Also, the sound level would fluctuate without even me touching the volume buttons. Sometimes, when I decreased the volume and increased it, it wouldn't increase and if I decrease it to zero, then even when I would increase it to full I wouldn't hear anything.
Flashing nuclearom fixed everything except the buzzing sound. To get rid of buzzing, I installed Viper4Android but instead of fixing it has brought back all the problems that existed earlier.
Also, the problem is only with phone speaker. The headphones and everything work fine.
Please help me!! I don't think it is a hardware issue because all these problems turn up on their own and they get fixed on their own for a time being.

Seems like you have nearly the same problem with the speaker:http://forum.xda-developers.com/zuk-z1/general/low-speaker-sound-t3500648
I think the sound problem could be an hardware issue

I said it's not a hardware fault because sometimes when I would clear data and cache of Audio FX and force stop it, everything would come back to normal. However it worked most of the times but not always.

And without audio fx? Did you wipe system, data every time you install other roms?
When I would force stop audio fx the sound would become normal. Yes. I follow the normal procedure before flashing roms which includes wiping everything.
I forgot to mention one more thing. The ringtones would work when there was no notification sound. And after I unlocked the bootloader, the notification sound problem was gone but the buzzing remained. I know it sounds freaky.
And if it's hardware or speaker problem the buzzing shouldn't be there at low volume. But in my phone, it's always there. In my experience, I feel like it's a software bug. When i listen to some song and it buzzes, I can notice that the volume increases and decreases on it's own as if the system is trying to create a balance.

speaker is REALLY LOW only during phone calls

hey there,
I use speakerphone a lot while talking on the phone and had no problem with it.
one day it stopped producing the loud volume it used to and it's REALLY LOW since then. As if it's not on speaker at all.
there's NO problem with the volume while playing/watching media; NO problem while talking on the phone with my ear near the phone or with an ear piece. ONLY WHILE IT'S ON SPEAKER.
1- it's NOT connected to any update (it started on 7.0 and yesterday i updated to 7.1.1 hoping it will help, but nothing has changed)
2- my 6P in not rooted
3- it has stock rom
4- MAYBE it's related to an app i installed called "DRUPE" which affects the phone, but it didn't start immediately and didn't get fixed after remiving this app, so i can't be sure.
5- i've tried SAFE MODE, but it didn't solve the problem
6- i've tried looking for a solution in the settings but nothing there affects the volume of the speakerphone or limits it.
7- i've wiped the cache - NOTHING
the fact that the speaker works fine during media playing shows me that it's not a hardware problem, but YOU ARE THE EXPERTS' so please help me.

In call speakerphone issue on Android 8.1

Hi,
I never had any issues with my 6P, but out of nowhere, observing since few days that my speakerphone whether be in regular phone call or whatsapp call is not working. However, audio plays fine otherwise in apps like youtube etc. I tried doing factory reset, and reflashing 8.1 stock, still didn't help.
I tried going to 8.0 Dec firmware but ended up in bootloop issue(which I never saw otherwise), so re-installed 8.1 Jan package.
This is driving me nuts not being able to use the device for whatsapp kinda calls.
Any help is greatly appreciated.
anyone please?
Do you mean people can't hear you or you can't hear them on speaker phone? If other apps are working, it's not speaker but mic problem.
I can't hear on speakerphone, others hear well.

I would do a complete wipe including internal (back up everything.) Then flash latest 8.1 with bootloader, vendor and radio through fastboot. If still doesn't work must be issue with hardware .
I have the same phone and the same problem. I doubt it's a hardware problem. I don't have a solution either as I've tried many things.
Same issue with mine, they haven't missed off the lines of code again, on speaker phone audio is only coming from 1 speaker.
I still have this issue, has anyone managed to resolve this.
Same issue here. I thought it was Bluetooth related until I tested it today with Bluetooth off. When making or receiving calls sometimes audio will not work at all thigh speaker phone or regular call audio out.
A temporary fix for me is turning speakerphone on and off a couple times then audio is usually recovered.
I noticed this typically happens when audio interruptions occur for instance your listing to Spotify via speaker or Bluetooth and then make a call causing an audio Interruption to switch to call audio from media audio.
Definitely not a hardware issue and very annoying hoping to have a phone for more than 2 years without so many issues.
