earpiece grille not producing any sound - Redmi Note 9S / Note 9 Pro (Indian Model) Question

As title suggest, no sound come out from the earpiece grille/upper speaker. So whenever someone calling me, I can't hear them and have to resort to use speaker or plugging earphone.
Attached picture are my spec, and "play music by receiver" test that I have done.

Same problem here.
I was using V11.0.4.0.QJWEUXM (EEA), changed to V11.0.10.0.QJWMIXM and still have the same problem.
From time to time speaker (earpice) work ok.
I made a test with an app Speaker test from Playstore and it works, so i think its a software problem.
I think that the volume go to low because i can here something but at a volume to low.
Any sugestion what to do next?

Make sure your speakers not on mute by accident. Go into settings then Sound then volumes. If they all up n still no sound, then try a reboot.
already tried:S im trying to factory reset as we speak
Has sound every came out the speakers before? Or it just seemed to stop for no reason?
no i just opened the box and i havent heard a sound from the speakers

[Q] Sound/Mic Messed up

So I've been running Unnamed 2.21 and the latest Entropy's 3/7 DD for it and it's been rock solid for months without issue. This morning, my alarm went off and woke me up. Tonight, the sound no longer works! Or rather, it works only in specific scenarios. If I plug in earbuds or headphones into the jack, I can hear everything and the mic picks up sound (plugged == working). If I unplug the earbuds, the phone produces no sound and doesn't pick up anything with the microphone. However, if I make a call, and then press speaker, then I will get sound and can talk. And if I take it off speaker, it will work normally, but only for that call. After ending the call, the sound and microphone stop working.
Things I've tried so far:
Factory Reset/Data Wipe
Turned off phone, removed battery
Checked for dirt/debris in mic or speaker locations
This is the closest thread I've found to my issue, but it didn't get very far: http://forum.xda-developers.com/showthread.php?t=1520359&highlight=sound+only+works+when+plugged
Any ideas what could have suddenly brought this on? During this morning and this evening I made zero changes (to my knowledge) to the phone. Very frustrating problem, obviously...
Sometimes when you flash stuff some folder permissions get messed up. Try fixing permissions in recovery.
Does your volume button work?
Have you checked your sound settings?
Have you tried resetting your default sounds?
I tried that. No dice. Volume button works. Sound settings checked for idiocy. They're fine, nothing is silent. I suspect something wonky happened or is going on with the headphone jack (phone thinks headphones are plugged in, I think this would explain the weird behavior). I've tried this app: https://play.google.com/store/apps/details?id=com.woodslink.android.wiredheadphoneroutingfix But sadly it didn't seem to help me. I'll give a go to cleaning the headphone jack.
update: ok it looks like the headphone jack is indeed the culprit. if i pull up the music app, plug in headphones, i can hear it. i unplug the headphones, the app pauses the sound, i hit play, it plays and i can hear sound from the phone speaker. however, right now it is only lasting a little while before i imagine it detects the headphones again and the sound cuts. this is pretty repeatable.

[Q] Speaker completely stopped working

My speaker COMPLETELY stopped working a few hours ago!!
Any type of audio that is routed through the rear speaker is now nonfunctional: e.g. ringtones, notifications, alarms, speakerphone, audio from music/videos, camera shutter, audio from video games!! Audio now only works if I plug in headphones, or if I route it to a bluetooth audio device.
The only thing that works is the front earpiece during a call.
Does anyone know what on EARTH could have caused this, and how I can fix it!?
Thank you...
P.S. Before anyone asks...my phone's software and hardware have not been modified in ANY way.

This seems like it would be a hardware issue, maybe software. If is software maybe you could factory reset (I know you probably don't want to do this), but this sort of thing happened to me. After I reset the phone my speakers ended up working fine after that. I hope this could help you out with your problem. Let me know how this turns out for you.

[q] noise cancellation issues in earphones

i have been using XZU for over a month now but one thing bugs me a lot, whenever i call and talk via using out of box earphones, i can distincly hear the background sound myself and somehow instead of cancelling that background sound, its amplies it and send it to the other end, ive heard many of my callers tell me that they cant hear my voice as the background sound is a lot when im not in such a noisy atmosphere.
anybody else has faced this issue? any idea whats wrong and how i can solve it?
I am experiencing exactly the same issue. The headset picks up all the background noise when I am having a call, and it is annoying because I can't hear clearly what my caller is saying.... I'm sure it is a bug... Am on software update 532 and this is really bugging me

In settings/call settings there are some tick boxes you can try:
Hearing aids
microphone noise suppression
speaker voice enhancement
If they don't work then it must be a hardware issue. (ear piece with mic)
Personally I've never used the headphone set. I use the SBH-52 bluetooth unit

I confirm the same problem does not exist in Bluetooth headset but it only happens when you use a wired headset like the Sony MH750 supplied in the box. I have tried using other wired headsets and the same problem exist - your earphone just plays also the sounds that are received in the microphone so you are not only hearing the caller but you are also hearing your own voice as well as the noises of the surrounding environment.... really really annoying.

Hello, i'm having a weird issue with my phone's mic.

Hello, first I want to apologize for my english, it's not my first language but I will try my best.
Well, I have a Blu Life 8 XL with KitKat 4.4.2 (I updated it to Lollipop, then the mic issue starts... I restored factory default config and now its on KitKat again) and after 2 weeks my mic stopped working. I tried everything on the net to fix it but nothing seems to work (disabling noise reduction, cleaning the mics, the paper on the back of the battery that works on nexus 5, disabling google search, etc).
Making tests with the phone's sound recorder I suddenly found this:
When I record something the app seems to be recording (the needle moves just as if the mic capture the sound) but when I play it only noise comes out (like ground noise, static noise).
But if I plug my earphones and play the same recording, now I can hear what I recorded, so the mic is not the problem I guess.
If I record something with the earphones mic, I can hear it with the earphones, or the phone speaker.
Also when calling, I must use the loudspeaker or the earphones becouse otherwise people can't hear me.
Any recomendation, help or something?
