Awful Popcorn Noise On Google Hangouts Video Calls - Xperia Z2 Q&A, Help & Troubleshooting

I have regularly used Hangouts on my other devices and while the quality has never been great, it got the job done.
On the Z2 though, Hangouts is unfortunately completely unusable for video calls due to an awful and constant noise.
As soon as the call connects I hear what sounds like popcorn popping and this only increases with time or trying to talk.
Mic noise suppression makes no difference and neither does turning the mic off and in again as the noise comes straight back.
It's very disappointing that this great device is seemingly incapable of handling a simple video call, does anyone know of a solution?

Android noise cancelling too good?

Hi guys, I'm developing an app at the moment, the idea is to be able to play a sound snippet during a call that the other party will be able to hear.
its all in place, except seem to have hit a bit of a road block, during the call, i press the button, the sound plays through the loudspeaker (very loud) yet the other caller hears nothing. I have disabled noise suppression in the call settings, that allowed me to hear a teeny faint. This is not music or anything so it doesn't need to be clear but is there anyway to get this working? I have tried speaker phone it didnt really make much difference either. Why is my budget phone with no noise cancellation features so good at blocking out any sounds it makes itself from the mic??

[Q] Constant loud high pitched sound when call recording

Hi,
I have a Xperia Mini ST15i with Carbon KitKat 4.4.4 ROM ( http://forum.xda-developers.com/showthread.php?t=2577517 ) which was a call recorder feature. After enabling it, when I press record during a call I hear a constant loud high pitch noise. Not just me but the other person too.
The call does get recorder but you can't hear anything due to the high pitch noise and also because it's impossible to have a call with that loud noise constantly in your hear lol.
I installed a few call recording apps and none record and the only one that was able to also triggered that loud constant high pitch noise.
Is almost feels like some sort of protection but it's really annoying. Any ideas what this is and how to stop it?

Mic issues - pops and lots of noise

audio and video recordings with my compact constantly pop and pick up a lot of noise and occasionally a high pitched sound. Has anyone else ran into this problem? Changing the mic sensitivity from auto to medium helps a little but I'm guessing I need to get it repaired.

I've made a few videos with mine and no problems. I do get an echo on speakerphone but that's it.
i've got this problem when recording calls
I don't have direct experience, but I have read that it is wise to switch to airplane mode to avoid crossover from network connections.

Low quality audio while in an internet call (Skype, Discord, ...)

I recently switched from an iPhone X to a Samsung Galaxy S9 and while I love the phone there is just one big problem:
When I'm in an internet voice call like Skype, Discord, etc... the audio is REALLY low quality. Like the bitrate is dramatically reduced or something.
I found out that if you call your voicemail and put it on hold during the internet call, the issue is temporarily resolved (until the voicemail automatically terminates) and you can perfectly hear the other side.
This is a really big issue for me and I'm out of ideas on what to do. Is there some setting in the phone that I'm missing to fix this?
Oh and something else that happens while in an internet voice call: ALL audio (except a phone call) quality is lowered. Even playing Spotify or Youtube or playing a game with sound is absolutely unbearable while on Skype with someone.
I'm using the default samsung AKG wired earphones.
Any advice?
Thanks!
I feel S9+ really having a bad internet connection. I'm not sure what it caused. My iphone 8 works well, but somehow It's reallly slow watching videos on S9+... However, voice call is fine.
I have the same problem.
For example if I listen to radio at the phone and somebody calls me via WiFi-Call or VoLTE, the radio quality is very limited. Also with the "call"-speaker. If the call is via the normal mobile network, the radio quality is perfect.

Question Poor in-call audio quality (muffled)

Hi everyone.
Just got my Edge 40 Pro and made a few calls on it, noticed a mediocre sound quality.
In-call sound is muffled and there's a general lack of clarity to it.
WhatsApp voice messages suffer from the same issue.
Problem is both on earpiece and speakerphone mode.
Also noticed that the network tones - the beeps you hear before the called person answers the phone - are unequal in length, one is short, the next one is long, and they have a reverb-like noise.
Other media like YouTube or Spotify is unaffected; in fact it's crystal clear.
Can anyone relate on this?
All things considered, I'm thinking there's some badly tweaked "audio enhancement" at work here.
Network operator is Iliad Italy.
Thank you
