[Q] no sound on calls: hardware or software problem

My Samsung T989, which was running Cyanogen 10.1.3, recently starting having the problem where I wasn't getting any sound from the earpiece during calls.
Speaker phone works, headphones work and the person on the other end can hear me (so microphone works). But nothing from the earpiece.
I've tried every setting but nothing. I've also tried Cyanogen 11 just to see if perhaps it was a bug that has been fixed, but still no sound, so I assume that this is a hardware problem.
Is there any way of diagnosing this better as either hardware or software? Any known fixes?

WTF is the deal with AOKP 10.1 MR2 and Sound

You are not the only one. Mine the sound other than calls is GONE! I am trying to figure this out. Tried to Flash the ROM from a clean flash with reset to factory and the works and went directly to AOKP ROM Directly with the latest Gapps. No dice. The phone ear piece works but speaker phone and any thing else via the speaker does not work any longer. I am dead in the water here and need a fully functional phone.
This is not my first rodeo. I have flashed many Andriod devices, Cliq+, Nexus S, Nook Color, Acer 500 etc... and the Galaxy S II.
Heck I am also now having issues with the CWM Recovery as well. I can not flash it current. The CWM ROM Manager says flashing and never completes. It has Root privileges. Really has me beside myself at the moment and it is my primary driver so it is interfering with WORK now and really has been ANGRY!

Maybe try out different radios or make sure you using the required version of TWRP?
I'm using UVMC6

Mic volume issue after EU OTA

Hi all,
Quick question, has anyone experienced issues with the microphone while using Skype or Hangouts after the latest (last week's) OTA for Europe?
At first I thought it was bad design on a case I got, but the issue persists even without the case (and there actually is a hole in the plastic for the mic), tried Hangouts to make sure it wasn't just Skype, so I'm thinking it might have to do with the OTA update.
The mic wasn't doing wonders with capturing before, but it appears to be unusable for Skype now unless the tablet is held at the same distance as a phone.
On a relevant note, is anyone aware of any tools that could help adjusting mic gain or disabling the automatic gain control/ noise cancellation features?
ROM is stock LG, rooted.

Me too
Same here with the exact same setup.
I've tried alsamixer but this proves useless until you know witch setting is involved among hundreds of available mixers.
I wonder if an external bluetooh or USB microphone is not a better option.

Same issue
I just recently got the G pad and I definitely have a problem with the mic. Is this happening on all the G pads or do you think is a hardware issue on my device?
I tried with Skype and Hangouts and my voice was barely audible on the other end. Just to make sure it was not my internet connection I tried with my old trusty Galaxy S2, no problems there so it is definitely a problem of the G Pad.
I have no screen, warming, yellow lines, light bleeding or any other issue. So, the device is perfect except for the mic, do you think it is worth to take it back to the shop to exchange it for a new one or this will not cure the mic problem?
Any luck tweaking the mic in software btw? Finally, has anybody tried to use a bluetooth headset and microphone with it, is it possible?
Thanks!

I am also having mic issues currently on sw ver v50010a.
it seems very quiet. update is downloading so will see how it compares.

I'm on software ver V50010b and I keep having issues with the microphone.
Don't know what to do... the rest of the tablet is perfect, so I'm afraid to exchange it just for this issue and get a new one with more problems.

Hi all.
Has anyone found a solution? I have the same problem with micro when using skype. When I use the micro in Dictaphone it works fine so the micro as such is ok.
For the software, I have V50010b. Thanks for your help!

Audio quality on Lollipop

Hi
Has anybody noticed degraded audio quality with any of the lollipop roms?
I have a Bluetooth car stereo with a subwoofer and on KitKat (ARHD) it sounded sweet but seems to sound awful on Lollipop.
I've tried ARHD and I'm not on Leedroid and the H/K audio mod has helped but it still sounds poor.
Thanks.

Yes, I noticed. Completely stock though, unrooted and all. Haven't tried blootooth yet, but sinply calling from my office is way worse - it takes longer to connect, quality is poor, disconnecys often. Lollipop is bad any way I look at it.

Hey uniflex_
I'm hoping this gets sorted, I wish I hadn't upgraded now.
Can I go back to KitKat? I'm wondering as I've flashed the updated FW.
Thanks

The way I understand it (and I'm sure there are many more experienced people here who can correct me), one has to root the phone, gain S-off, find the RUU on this forum (or elsewhere), and use it to install KitKat. I'm not sure this will bring the phone back to how it was before the update, so for now I'm trying to work with the seller - I bought the phone less that 6 month ago, which means I can simply exchange it. The question is, whether they have any of the KitKat phones left.

Hi
I'm sure the audio issues are probably caused by the FW as opposed to the OS - maybe somebody else could verify this?
I'd imagine this will be fixed shortly but you should still find a kitkat one. I would go back but I'm too scared to flash via RUU. Just seems like something that would go wrong for me lol.

I had similar problem with audio although the camera took noisier photos just converted to gpe 5.0.1 .everything is working good so its definitely a fw problem not 5.0.1

[Q] Sound + Root Issues on Z1C

Hey folks,
So I have a problem with my Sony Xperia Z1C (D5503), and would appreciate some input on my theories as to how to fix it, at which I have yet to be successful.
I live in China, and I bought my lovely device on Taobao a few months back for a very discounted price (risky, of course, and to be certain this is where the issues stem from). I purchased the Hong Kong version instead of the Chinese version, because the Chinese version is built to block Google Play by default and comes with a bunch of junk apps. Anyway, I was stupid and didn't get a chance to use it before the seller's 7-day return policy was up, so it was too late for a return after I found out about its issue.
The issue is this: when I receive a call, the caller cannot hear my voice. Not that it's completely silent, it's just muffled and quiet. I've tried various things, turning on and off the Microphone Noise Suppression option, adjusting the caller's sound options, but nothing; it seems there's a defect with the microphone. When I switch to speakerphone during a call, however, there are no problems. On a related note, the same thing is true when I use apps like Skype and particularly WeChat: if I send someone a voice message, they can barely hear me. Only when I use a headset are there no problems. So, to continue using this phone, I've succumbed to bringing my headphones around with me and plug them in when I receive calls or have to send a voice message.
So the microphone's screwy? Interestingly, when I record with other apps, like the Sound Recorder app, there are no problems. It picks everything up perfectly. It must be recording on "speakerphone" for this app, if that makes sense; right?
Anyway, I was wondering (hoping) if the kernel loaded on my phone has anything to do with it. It's the stock kernel but one that seems to be used more for the Xperia Z1. Since I'm mentioning it, here are all the specs:
Model: D5503
Android Version: 4.4.4
Baseband version: 8974-AAAAANAZQ-10270054-61
Kernel version: 3.4.0-perf-gaee6e5a [email protected] #1 Thu Oct 9 09:14:33 2014
Build Number: 14.4.A.0.157
Anyway, I still have this hope that the problem is fixable. I am inclined to wait for the rollout of Lollipop for the Z1C, but that could be months, and this has been going on long enough as it is.
I'd appreciate any input, especially if you think I'm on (or not on) the right track thinking that flashing a new kernel may make a difference, assuming it is a conflict with the firmware. Or, perhaps I should just accept that I was sold a defective product for a decent price (I mean, everything else is working OK...).
Should also add, running the service diagnostic test for both primary and secondary microphones provides clear, audible results.
A few additional details, that may be of interest: my phone is rooted, with SuperSU as the app. The stock version of the app is a system app, but when I update the app, it loses its system app status and also does not successfully update the binary. I couldn't install busybox for the longest time but was finally able to do so through the advanced root options FlashTool. This is interesting, I think. Also, there is no recovery mode.
Thanks for your time!

Looking at the Sony forums there are a lot of complaints about muffled calls and poor microphone on voice calls, with no comment from any Sony moderators, which isn't a good sign.
One suggestion was to turn off the "Microphone noise suppression" option in call settings. Another was to not have the call on speakerphone.
Someone else suggested editing build prop, which if you've got a rooted phone should be easy.
persist.audio.fluence.voicecall : false
I think this turns the audio post processing off.
You should get recovery working, try installing the latest recovery from NUTs dev page, this installs from your PC. This will help you get a working SuperSU as it will restart in recovery mode.
The file you are looking for is called
Z1C-lockeddualrecovery2.8.2-RELEASE.installer.zip
Once you have recovery you could do a nandroid backup and experiment with a factory reset.
If all that fails, it looks like it's a problem limited to Sony stock builds, so it might be worth experimenting putting a CM rom on your phone. Obviously read up on how to do this properly, and make a copy of your TA partition so you can back to stock if you change your mind.
This page is a good place to start.

Hello, everyone.
