[Q] Problem in sound quality while ringing...

Hello...
I am using HTC Aria from past 6 months. The phone is really good.
Recently from past 2 months, i am facing problem with phone ringing.
HTC Aria has got an amazing speaker in the rear which on playing music provides excellent treble quality.
While selecting an ringtone in the mobile, the speaker is playing the tone in excellent quality, but when i am getting an incomming all, the same tone plays with a very poor quality (no treble at all).
I was using Android 2.1 initially and i have faced this problem after using the phone for 3 months. Later I have installed Android 2.3 Cyanogen 7. Initially for one day, the ringing quality was solved with excellent quality and after that the same problem started again.
I am unable to understand what could be the problem.
Could anyone help me in solving this problem?
Thanks..

[Elephone S8] Loudspeaker issue

Hello to all,
I got an Elephone S8 for my girlfriend and in general I think you get a lot of phone for the price!
One thing I noticed is that whenever you have a WhatsApp call and you turn on the Loudspeaker on the Elephone S8 there will be distortions in the audio.
It is not hearing an echo or something it is more of a static noise and squeaking that can be heard every few seconds (it is not constant).
Did anyone having that phone also experience that problem so far ?
Same thing here, but only with WhatsApp calls and WhatsApp video calls.
+1 same issue (+ with Viber)
Only with Video call and turned on Loudspeaker
Same Issue

Yeah my girlfriend recently bought this phone too, I found she had the same problem with Whatsapp, skype and google duo voice and video calls.
Same sort of noises, static, video quality was terrible and a squeaking microwave high pitched noise intermittently.
When we switched her wifi off and used her 4g it was better but still similar issues.
The phone is amazing but this is annoying, i hope there is a fix for it as it is quite an important feature.
Has anyone resolved this?
I had distortion and noise issues on speakerphone until I realised I had the phone at full volume. Reducing the volume a couple of notches got rid of the feedback and resulted in much better call quality.
Don't know if this will resolve your issue. Good luck!

audio from earphone sounds like muffled / clogged only when playing games

i have weird issue with the audio when using earphone
when i play game, the audio are muffled, kinda like when you got water in your ear and the weird thing is, this only happen in games.
this didnt happen in youtube and music which is really weird, everything works normal here.
also when i press recent apps and then back to the game again, the audio quality return to normal, but only last for few seconds and then become muffled again.
Anyone experiencing this?

Yes facing the same issue.
I haven't faced such issues. Have played PUBG and Asphalt 9 so far. Will update this reply if I face such problems. Probably just a bug.

No I'm on 9.6.14.0. So it's a software issue after all. I tried playing games like Batman:EW, Asphalt 9 and the lot again after reading this post. No dip in audio quality whatsoever.
Facing the same issue
Yeah. Exactly. I am also facing the same issue. It happens only in games. I tried PUBG and Asphalt 9. Audio is fine in music and video players. It happened after the last update 9.6.18.0.
Same issue here.
Sometimes I also hear some kinda static noise too the in-game voice chat is not that bad but other than that all the other in-game sounds are messed up. ?
interesting find today , under additional settings ,there is a ear buds mode , tried two earphones , one brandless , other one Westone both not detected , tried mine AKG headphones finally detected ,weird i think the type of male jack has something to do with it to work properly?

It's a 9.6.18.0 specific bug as far as I've seen on the forum. Can anybody confirm using 9.6.18.0 and not facing any audio issue? I miss PUBG

In call noise/ distortion/crackling

I have bad call quality while in call. There are some crackling noise coming from the earpiece, but that is just happening while in call. I disable the big/lower speaker and test the earpiece by listening voices, music from youtube and everything is fine than, so the earpiece is not defective. Are there some way to improve call quality? I think that this problem is software related. I am on 10.2.2.0 stable. Thanks

Hey, i dont have solution but my pocophone does the same thing, it is pretty annoying. I returned first 2 pocophones because i thought it is some hw related issue, but this is my third pocophone and it does exactly the same sounds as first two did so i think this is just either software related or bad engineering if the phone. Because my old redmi 3 did not do anything similar and the phobe was 1/3 of the pico price.
Sound is like buzzing/static noice/interference, and as you said, only while calling with someone. Tried different providers, reseting phone, downgrading to basic android but nothing helps.
Any solution appreciated
Even I have experienced it...
Noise can be heard through earpiece...
Also echo/noise is heard to the other person in call...
Everyone complaints me regarding it while in call... Also this is reduced whole using earphones
Why doesn't Xiaomi take any actions on this?
Even I'm facing the same issue.
Pocophone F1
I have the same problem here. any Solution?
same issue guys, i am on 11.0 .5. i am experiencing it since last two updates

Redmi Note 4 sound issue - works only headphones

Hello everyone!
The issue I'm dealing with has to do with my Redmi Note 4's sound. The only way I can hear a video or song is putting on headphones. The sound is fine then. Without the headphones, a very low static-like noise comes out of the phone while the video plays. When someone calls me, the phone behaves like it's on mute. But when I pick up, I can hear the other person at the end of the line clearly.
I hope I explained this clearly enough. Thank you in advance!
