[Nexus 4 Q&A, Help & Troubleshooting] samabalone:
Just sharing my experiences I made with having no audio during phone calls on my N4.

I was running CM 11 M12. The problem occurred first end of December. And stayed for me permanently, normal restart did not help. I had to switch of first all data connections and then restart the phone to fix the problem. But with turning on the data connection again the problem reoccurred instantly. Reproducible every time.

After one painful week with a lot of research, I found out that this nasty bug seemed to exist since 2 years on various OS (stock and custom) and various HW. But this does not imply that all this similar "no audio during phone call" reportings are caused by thE same reason.

Clearing app caches and switching from dalvik to ART which was suggested by some users, did not show any effect for me. I did not trust the weird disable check inservice workaround, so I did not try that one. But I ran into one interesting user experience which was about fiddling around with the Micro USB port of the phone. I found this one very interesting cause day before the problem appeared first to me I was cleaning my USB port with a needle. So I thought give it a try. I took my charging cable and plugged it in and out multiple times very fast. Did a restart (with data connection turned on) and, what the f***, the problem was fixed immediately as of this point.

I did not had the problem since then anymore. Was running 2 weeks with CM 11 and since that I'm on CM 12, still don't having this problem anymore.

My explanation is, that maybe the USB port gives some weird input signal, which then is interpreted by the OS in a weird way to cause to mute the audio.

But of cause it could have been pure coincidence too, nevertheless you could give it a try, it does not hurt ;)

Problem....I think I have the no audio bug with this rom..but I have changed my view. I noticed when i send a voice message using apps like whatsapp. That person doesn't even get my voice as well. Meaning my voice wasn't even recorded. Do you guys think that my mic is busted??? I am planning to disassemble and put a new mic in.
[Nexus 4 Q&A, Help & Troubleshooting] flusi100:
I would not suggest replacing any hardware as it obviously is a software bug. To proof this, simply install another ROM (e.g. Omni, or CM12).
[Nexus 4 Q&A, Help & Troubleshooting] dicksonjoe:
Yeah!! you're right. i flashed the new cm12 with new gaaps. Problem finally solved!

FYI... The workaround I posted here (I can't post links? WTF? Dumb. I'm trying to help for fuks sake.) https:// code.google.com/ p/ android/ issues/ detail?id=82949#c452 and https:// code.google.com/ p/ android/ issues/ detail?id=82949#c454 on Jan 13th has worked without fail since then. In fact, I believe someone in this thread already mentioned it. No phone audio is a pretty big deal so I figured I'd let y'all know how this workaround is faring. It's faring great. Although, I am considering switching to PA or something because it looks like a CM11 M13 is no where in sight. :(
[Nexus 4 Q&A, Help & Troubleshooting] ebustelo:
I have exactly the same problems that you. Lollipop has problems with bluetooth in Nexus 4 (car and smartwatch). Now I´m in CM11 with this big audio problem during calls.

Please, let me know what solution do you take. If I find something I will tell you.

Regards.
[Nexus 4 Q&A, Help & Troubleshooting] nd4spdbh:
again, still rocking OMNI rom, and since i flashed omnirom i have had zero issues with no call audio, and have not had to do any workaround or fixes.

This is obviously a CM issue.
[Nexus 4 Q&A, Help & Troubleshooting] yantheman:
The app created by user in this thread to disable check in and reenable works for me and no battery drain. I installed and wiped cache and dalvik and rebooted and it works like a charm!

[Nexus 4 Q&A, Help & Troubleshooting] hans moleman:
I've been having the same problem on cm11 so updated to cm12 nightlies with clean flash and have had exactly the same issue on cm12 for some weeks. I've tried every solution I can find- some work for a bit longer than others but still end up back at the same place with no in call sound. I've read it is a problem for nexus 4 & nexus 6 lollipop stock roms also. It seems to happen when play services updates itself but I can't find a way to stop it updating to check for sure. Seems a lot of the solutions on the net to stop it updating don't work on LP. Thinking of going back to JB because I need a phone that can make and receive calls but don't know if play service update will screw that up too? Nightmare, I think I've got a Nokia 5110 in my drawer somewhere I might see if it still fires it up, at least I'll be able to make calls!
[Nexus 4 Q&A, Help & Troubleshooting] dicksonjoe:
I know exactly how you feel. A phone that cannot make any calls is not considered a phone at all. I've been suffering with this problem since November. But then again lately I've been using my HTC HD2. A few generations old but atleast I can make damn calls with it. If this problem still persist for the next 2 months. I'm going over to the lg g4!
[Nexus 4 Q&A, Help & Troubleshooting] mx82:
The bug reappeared for the fourth time on my nexus4 (CM11M12).

I installed the new Google Play services 6.7.74 and rebooted (+ cache/dalvik wipe).

It didn't work. The new version has also the same bug. :eek:

It helped like always to reboot, wipe cache and dalvik cache and enable+disable the checkinservice after rebooting.
[Nexus 4 Q&A, Help & Troubleshooting] hans moleman:
I downgraded to cm 10.2.1 from cm12 and it worked fine for a few days until play services updated itself. I uninstalled the play services update and blocked it from updating again and it lasted about a week before in call sound problem came back.

Has anyone tried installing the soundabout app and changing phonecall audio to earpiece? It works for me (for now anyway)
[Nexus 4 Q&A, Help & Troubleshooting] Thomas_xxxxx:
Does somebody know how to fix no call sound? I have the same issue on Galaxy Trend Plus with CM11. Thank you.
[Nexus 4 Q&A, Help & Troubleshooting] JAS_21:
Whenever I make or receive a call I have several seconds when I can hear the other party but they can't hear me. It's usually about 5 seconds before they can hear me speak. I read some of the other posts and google searched the issue, but it seems like other users have issues with the microphone not working at all. I am currently running CM12 with stock kernel, and also had the issue while using Rastapop. Has anyone else experienced this, or have an idea of what may be causing the issue?

Try out Aptoide. There are all versions of any app, also google play services but not sure if all older versions.
[Nexus 4 Q&A, Help & Troubleshooting] cspaulding:
I use play services 5.0.89 (1307510-038) from Banks gapps and no auto-update. Updated automatically only google play.

Try this gapps

d-h.st/F7e

After installing CM11:

1. install gapps

2. disable auto-update in google play

3. go to Settings>Apps>All>Google Play Services>press Uninstall Updates

With this play services work only old gmail, maps, etc

Did the bug never appear on your nexus 4 with this configuration ?
[Nexus 4 Q&A, Help & Troubleshooting] cspaulding:
I tried it on xiaomi mi2, but the bug was same. Now it does not appear. I think that the auto- update of play services is connected with free space in the system partition. After installing gapps I have 9 mb free in /system.

This appeared to work for me for about 3 weeks, making me think I've finally come on top of the issue.

Looks like it's good-bye CM. What a waste of time though!

I don't really want to spend money on new phone but it's been about 4.5 months already that I can't call and I see no hope it will be fixed soon.

An none of the current workarounds for this problem work for me.

Disable GMS Checkin service should resolve the call problem.

But what about this GMS Checkin service? Do the disabling of the service may cause problems?

What does exactly this GMS checkin service? What I'm going to lose, by disabling it?

Thanks.
[Nexus 4 Q&A, Help & Troubleshooting] Rev4:
I disabled checkin service and this fixed the problem. But I am experiencing huge battery drains. Is there anyway to fix this?
[Nexus 4 Q&A, Help & Troubleshooting] bmmrohrer:
I had this problem awhile back and when the disable checkin service trick was found, I did that and all my problems went away for maybe a month straight without any setbacks. Suddenly, it came back and came back worse. Now this only maybe my personal experience but I restored my phone back to a point around the time I had fixed it (almost a month ago) and my phone was fine again. The only difference between the phone before and after my restore was I had switched from the old regular android email app to the Gmail app. I don't know if that specific app is the problem but it seemed to give me trouble in my own personal situation. Maybe this can help some others, so figured I would share my experience. Good luck to all.

Hi all!

I compiled CM11 from sources (version is of 04/18/2015) and installed it on my nexus 4. Whit that version the no audio problem during a call is never happened. The version of Play Service I'm using is 7.3.29

Unfortunately with this rom I have a battery drain by the mediaserver process...

I will try to compile again a newer version.
[Nexus 4 Q&A, Help & Troubleshooting] Rev4:
Any luck?
[Nexus 4 Q&A, Help & Troubleshooting] VegetaSSJ5:
Since I installed the new rom I did't get this problem anymore. Audio during calls work.

Unfortunately I have this battery drain problem, but I'm compiling again a new version (because the battery drain). I hope I can solve this battery problem. Then it becomes my definitive rom.
[Nexus 4 Q&A, Help & Troubleshooting] VegetaSSJ5:
I compiled and installed CM11 from sources, version 05/04/2015.

Audio during calls is perfect but I havealso with this version a battery drain by the media server process.

I will try to reinstall M12.... :(

EDIT:

I came back to CM11 M12 (installed and updated all apps). No battery drain by media server but I cannot hear anymore audio during calls....... :(
[Nexus 4 Q&A, Help & Troubleshooting] Rev4:
I wonder why only cm11 is having this issue and not cm12. And why this issue hasnt been fixed yet. I prefer to stay on cm11.
[Nexus 4 Q&A, Help & Troubleshooting] VegetaSSJ5:
Hi Rev4! I think they have solved this problem with the Patches after M12, because in the version compiled by me there was no problem with the audio during calls. But I could not maintain this version because the battery drain......

Cyanogen said that there should be a M13, but I learned that what they do is not what they say.
[Nexus 4 Q&A, Help & Troubleshooting] Rev4:
You are right, I hope they will still release M13. But keep up the good work, U might resolve this issue.
[Nexus 4 Q&A, Help & Troubleshooting] VegetaSSJ5:
Hi all!

Since three days I didn't have the problem. I found a solution (a workaround....). The checkin service has to be disabled, then audio during calls will function again. I don't know what does exactly this service, but I don't feel problems since I have disabled the service.

More info here: https://jira.cyanogenmod.org/browse/CYAN-5728

I think also battery consumption is better.

After 7 months I have again a phone which makes calls.... :rolleyes:
[Nexus 4 Q&A, Help & Troubleshooting] nadastry:
Is already known why this happened?
[Nexus 4 Q&A, Help & Troubleshooting] rpangelov:
Does any of you still suffer from this bug? I do truly believe this big is long solved. Anyway... I've seen some cyanogenmod users (no matter which version, mostly 12.0/12.1) experiencing the same issue - no sound on call except phone speaker. After restart it may function the first 2-3 minutes and after that the issue is coming back again. I've noticed almost all of this users had sound EQ application installed (for example viper4android). This issue is coming from EQ apps - I confirmed it my self by triggering the same "bug". Actually it is not a bug, but when you install EQ application, cyanogenmod doesn't know what to do, as it comes with AudioFX preloaded (also EQ application). LEAVE ONLY ONE EQ APPLICATION ENABLED! This will solve your issue - if you prefer to use any other EQ application, different than AudioFX you have to disable AudioFX, leaving only one EQ application enabled. If you leave more than one EQ application enabled, you will experience different issues.

For those who want to use Viper4Android, PLEASE INSTALL IT PROPERLY! Lots of users change from kernel, install applications which are totally unneeded... this crap will slow your device. Most of this app turns Enforce off, setting SeLinux back to permissive. Well... this is needed in order to install Viper4Android driver... pretty lame from the developers, as it is great application, widely used by lots of users. Forcing the users to turn Enforce off brings back some security issues which I prefer not to ignore... anyway. Please follow this steps in order to install ViPER4Android properly (I assume your device is already rooted and you already downloaded ViPER4Android from the official website!)!!!!:

1. If you use cyanogenmod enable terminal application (you don't need to download any terminal application as you have one preloaded already...) - Settings -> Developer options -> Local Terminal (This will enable terminal app - you can find it now between your apps)

2. Open Terminal and type: "su" (without quotes... it will ask you to grant root access.... grant it!)

3. Right after su, with root acces type this command: "setenforce 0" (again... without quotes - this will set enforce off, and will bring back SeLinux to permissive - do your remember what I said about the crappy apps and changing to another kernel? Well... this single command saved you all of this pain in the ass in it is more trustable way than changing core components of your system)

4. Start ViPER4Android - it will ask you to install it's driver in order to use. Do it. After that - reboot your device.

5. When your device boot up, open terminal again and type once more: "su" (grant root permission) and after that "setenforce 0" ( without quotes... you know?).

6. Start ViPER4Android - check it's driver status. If you followed this steps everything will be up and running ;)

It doesn't matter which sound EQ app you use, JUST REMEMBER - ONE AT A TIME! LEAVING MORE THAN 1 SOUND EQ APP ENABLED WILL DELIVER YOU UNEXPECTED RESULTS! THIS IS NOT A BUG!

If you still experience this issue... let me know :P

had this issue aswell, and while it is not really a solution, after flashing 5.0 (or 5.0.1 for the time being) everything works. so unless CM or Google will fix this i guess if u want to have phone that can acually make phone calls go for lollipop.

or wifi off and reboot :p
[Nexus 4 Q&A, Help & Troubleshooting] mhier:
I have the same problem. I believe I have found a solution: I disabled a number of services (using the DisableService app) of the Google Play Services app. I am not (yet) sure which of the services is actually causing the problem, and I am getting some warnings and frequent crashes of Google Play Services as a side-effect, but I do have audio in calls back even with data/wifi enabled. I am going to test one by one which of the services actually cause the problem, but this is going to take a lot of time. After each test, at least one reboot is required (probably better two) and I have to wait some time after the reboot before testing. I thought a number of times that I had found a solution, but it was going away after a reboot and/or waiting some time. Now with the disabled services it seems to work permanently.

This is the list of disabled services:

AdvertisingIdService

CheckinService

ClearcutLoggerService

DeviceConnectionServiceBroker

DispatchingService

DownloadService

FusedLocationService

FusedProviderService

GeocodeService

GeofenceProviderService

GoogleHttpService

GoogleLocationManagerService

GoogleLocationService

IndexService

LightweightIndexService

NetworkLocationService

PlayLogBrokerService

SystemUpdateService (was disabled before)

WearableService

This list is a bit random and arbitrary, since I just disabled all services I saw running after a reboot. I will update this post, when I exclude some of the services. Please let us know whether this is helping for you (beware that the problem might come back after some time and/or a reboot - actually a reboot is usually fixing the problem for a few minutes but it comes back then). Another hint for testing: I usually call my own land line number and see if I hear the call-progress tone, because that's already not working when the problem is there.

Update: I reactivated the first part of the list until including "GeocodeService" and the problem reappeared ca. 15 minutes after the reboot. I now invert the selection and will let you know...

Update2: I believe I can exclude this second part of the list. At least the problem did not reappear again so far (15 minutes after reboot). All obvious negative side effects (warnings and crashes) seem to be gone, too. I will keep it at this configuration over night and continue testing tomorrow.

Update3: The problem seems to be caused by the "CheckinService" service. I re-enabled all other services and it was still working. If I re-enabled that service again, the problem reappeared. Note that I have no idea what this service is doing! I don't see any side-effects, but this doesn't mean they are not there.
[Nexus 4 Q&A, Help & Troubleshooting] bmmrohrer:
Wow. This problem seemed to pop up out of no where sometime in the last couple weeks. Everytime i think i have it fixed it comes back again. I was on cm11 when it started, played with google play first with on and off results, and even went back to cm10 thinking it fixed it but it didnt. Seems to work after reboot but its only temporary. I appreciate the time some of you are putting into this and hope for a quick fix. Ill be watching anxiously.

I have manually upgraded Google Play Services to version 6.5.96 (1630522-036) and all seems to be working again, for the last 24 hours at least. Will update if it breaks. What a confounding bug.
