Sound echos during call - Nexus 9 Q&A, Help & Troubleshooting

I have a really bad sound echo during call at the receiver side. No matter what I use: messenger or hangout. Is there any way to fix this somehow?
I have stock 6.01 android rom.
There is no problem with my Nexus 5 with the same android version.

Do you have a case on it? If you do, take the case off and try again.

I tried, but the problem still persist. I tried on the same network, the receiver hears himself/herself during the call and my voice quality is poor and low volume.
I had the same problem once on a different device, but that problem solved somehow. Maybe it's just a setting problem.

I think I found a fix for this. I found out this is happening if the speaker volume is quite high, if I reduce it the echo stops and there is no complaint about my voice quality.
Any advice what can cause this? Noise cancellation?

Boomsound is your answer. I noticed this when I use hangouts. When I plug my earphones in, the receiver can't hear the echo anymore. When the speakers are loud, even the microphone can hear the output.

Noise cancellation?

I read the SGS2 has noise cancellation?
Can anybody confirm if this uses the dual microphone approach as used in the Nexus and
some noise cancelling headsets?
If it does, I'm guessing there should be an additional microphone located away from the 'proper' microphone.
Thanks

Yes it does have noise cancellation. The second mic looks like it's at the top next to the headphone socket.
can anyone comment on the in-call quality with the noise canellation? the nexus s has very bad call audio in noisy environments. my nexus one call quality is superb with the second mic.
is the SGS2 very good in this regard?
He talks about call quality and it sounds very good.

Does it also reduce non-stationary background noise ?
Is this noise cancelling mic used as one of the stereo mic's when recording video do you know?
Does anyone else's noise cancelling mic seem to turn itself off? Every time i make a call,the screen shows noise reduction off even though its enabled,i switch it back on but when i make a call again its off.
Can anyone see if this is the case on there S2 to see if its a fault or a bug. Thanks.

When do you see that message? Is it when the other end answers?
Cant say I have noticed it.
Does it only happen on speaker phone or BT headset?
It happens when the other person answers,a squiggly icon appears on the left. If u press the menu button you can select to turn it off or on.

As I previously said, are you using speaker or a headset?
Or is this just a regular call, ie you hold the phone to the side of your head?
Oh, and where are the settings for noise cancellation?
thanks
its just a regular call mate.

When your on a call press the menu button and the option to turn noise cancellation on/off is there.
I can confirm I get the same
If you've turned it on while on a call then disconnected that call and make another call is it still on or has it turned off again? Mine always switches off..
Yep thats what I get
Do you think thats a fault, its a bit annoying that you have to turn it on every time you make a call..
Unless the icon with the line through the sound wave actually means that its cancelling noise?

Can someone check voice record quality

I decided to try Sony's answering machine feature. I recorded a greeting. When I played it back it sounded like I was talking through a towel or something. I called my girlfriend and she said I sounded fine, so I don't think it's a mic issue.
As a check I downloaded 2 different voice recorder apps and both record with the same muffled sound.
Could you guys try and let me know. I'm on the most recent firmware 17.1.A.2.55.

Some new info to report.....
I'm hoping a dev reads this and can shed some light.
People have been complaining in certain situations that they can't hear me on their end. Usually in noisy environments (on my side)
I downloaded "Easy Voice Recorder" in an effort to run some more testing. This particular voice recorder lets you override the phone's default for
1) noise suppression
2) echo cancellation
Turning off noise suppression makes a huge difference. Still sounds like **** compared to every other phone I've had in the last 5 years but it's improved greatly.
Thinking back, the times when people complained about the call quality on my end, I'm pretty sure my Z2 noise suppression is to blame.
Two things then:
Someone please download "Easy Voice Recorder" and test how a recording sounds. Then disable noise suppression in settings and test again.
Secondly, does any dev know of a way to alter the default noise suppression functionality?
Again, as I have divulged in several threads, I am unlocked, rooted and have lost my DRM keys. If this is not an issue for anyone else I'm wondering if it could have something to do with that...someone please take a minute and test this for me..Thanks.
Hi I got similar issues. Look at my thread, "Bad call Quality".

Caller can't hear me clearly?

Hi
I have Xperia Z2 D6503,M rooted.
Recently i've been facing an annoying problem which is when someone calls me or i call them the other part can't hear me well but when i use speaker they can hear me very clearly.
can anyone tell me the problem?
Hi,
you may try to turn the Microphone noise suppression off in the call settings.
I faced similar issue, it was cutting off silent tones of voice.

Go into setting and click on call then their you will find microphone noise suppression and turn it off.
Mine mic is not good too, I disabled noise suppression but that help only a little

Pretty sure you need MM build 575 for that feature. It's not in 570.

@mascox14, Although the settings are somewhat related accessories, you tried to change the microphone sensitivity from there?
Settings / Sound and Notifications/ Accessory settings / Mic sensitivity
Look at what value is pre-made and test after that the microphone in the Settings / About phone / Diagnostics
Change it to High level and test again in service menu for results.
Will was surprised by the difference in the test.
Set mic equalizer to "bright" and see if that helps. I know equalizer is not supposed to be related to the voice sent but it helped for me.

Bad call quality

Is anyone else having problems with the call quality?
I also checked with HiCare and I sound very muffled when using the microphone.

Not for me for now
So what I found out is, that if I am in a quiet room and talk, then voice quality is very bad.
If I stand in a very loud area, voice quality is good.

i have the same issue lately. I will back up the phone then reset to factory defaults and if it's not helping I will send to service through the window.

Question Popping/crackling sound during calls on multiple apps [SOLVED]

Every couple of minutes I am getting a loud pop/crack sound during normal calls and the same behaviour on Whatsapp and Viber calls.
I tried both on speaker and without and the result is the same. I am running all the latest updates. The adaptive sound is disabled.
Also tried Stealth Audio Player to hear both the external and internal speaker on Youtube videos and I can't reproduce it except sometimes it pops when a video is started. I also tried recording my mic and it sounds clear without this popping.
Is there anything else I can try to fix or debug this issue? It sounds like it is trying to record or adapt the sound while on call even if the adaptive is off.

This kinda sounds like the problem I had, but ALLLLL the way back to my Pixel 2 XL!
If you're rooted, you can try what worked for me below -- although, I'm not up to date with Viper4Android (V4A) and I believe it's either EOL or is in the process of being updated to work in x64 architecture or there are newer updated branches or something... But if it's possible to lower the frequencies, you might luck out like I did on the taimen...
I Found a Speaker Distortion Fix
Like many, my phone has the lower speaker distortion on speaker phone calls and general audio, like YouTube, when turned up high. If you are rooted, I have found a solution to all situations except speaker phone calls. I installed Viper4android...
forum.xda-developers.com
Thanks for the help. I can hardly hear any issues while on youtube. There is noticeable pop when videos ending or starting. Some people are reporting motherboard issues with Pixel 7 leading to similar problems. I am trying to find if it is a hardware or software issue.
After further investigation it looks like interference. If I disable the mobile data and WIFI it seems to be a lot better. After 16 minutes call it was a very faint pop if at all. Does it sound like it needs a motherboard replacement or a future patch might fix it. Update: still happening regardless of connectivity on both the inner and outer speaker. I am going to RMA for motherboard replacement.
