Question Realme 8 Pro - Microphone problem - Realme 8 Pro

I have a problem with the microphone on realme 8 pro. It stopped working suddenly, first I thought that it was probably software related issue but nothing that I tried worked.
So I decided to replace the sub-board where the microphone is, I had another board for replacement but it's from a damaged realme 8 so I also bought a brand new one just in case. So now I have 3 sub-boards and the result is the same at each one, the microphone is not working. Also tried it with the new flex cables.
Now I only think about 2 possibilities, the first one, it's still software related issue but one that requires installing software once again instead of only factory resetting the phone. The second one it's a hardware issue but the problem is on the mainboard.
Mainboard no. E99824 I was looking for a diagram but can't find any, replacing or repairing SMD components on the board is not an issue but without diagram, troubleshooting it will take a few weeks, so maybe someone has one, or maybe someone has another idea?
One more thing, it also does not recognize the external microphone on the headphones doesn't matter if these are headphones for the jack or USB c, they can only be used to listen through it.

Update time, external microphones are working now. I tested both internal microphones using software and once again checked hardware and there is no issue there. The only possibility now is software related problem, something happened during the last update and it looks like there are no "drivers" for internal microphones. I already found a few people with the same issue at non-English forums so this is something that can happen.

Kaiser Microphone Problem with Loudspeaker On

Hi,
Does anybody else have a problem with microphone when loudspeaker is on during a call? Ive had quite a few people complaining that they cant hear me when Ive got the speaker on. As soon as I switch off the speaker, they can hear me fine. Does not matter if I place the mic close to me or move it further away, they still say they have trouble hearing me with speaker on.
Any ideas if I can resolve this? Have tried AGC setting with no success.
Thanks
I have the same problem for a while. Can't use speaker phone. It was working fine before so I am thinking some of the software that I installed render the speaker useless. I will try to backup everything and then do a hard reset to see if the problem still exists.
My Friend; I have the Same Case in my Kaiser and I post yesterday this issue but with no luck . we have to find a solution for this bugs, I tried something it might improve it a little ; during the call reduce the Speaker volume to be 2 degree only and it might help. But we have to know if it is a common in all devices or not
I tried the Hard reset but it is smae and no luck yet
I just tried the method proposed in abother thread here and it fixed the problem! I disabled the Microphone AGC in the phone setting and it works fine now. Save me some hassle.
are you sure of disable AGC as I tried but it is the same result
i have the same problem, and i don't have the auto mic gain enabled. i haven't hard reset yet, but it stopped working properly after i installed resco voice recorder and/or vito voice...
Looking at another thread, it may be that the speaker is half duplex. I.e you both cant be speaking at the same time. Wonder if this can be resolved?
My Kaiser comes by default Microphone AGC disabled, and the problem persists. Any suggestion???? thanks.

Precisely you are right. I do not think by enabling/disabling the Microphone AGC does help. This is apparently a design fault. I have got my set replaced from the service center but still having the exact problem.
I wonder if HTC can fix this problem! I read from one of the threads somewhere that one of the users found the MDA Vario III works perfect...though they are also of the kaiser family....

Same problem, and i haven't modded mine at all. Using the default ATT ROM and tried speakerphone, couldn't be heard...
I had the same problem when using my TyTn and attempting to use the speaker phone. I was hoping this would be resolved in the TyTn II but it's the same problem where the person you speaking to complains they can't hear you properly.
I think its a common problem in this model as my device is brand new and same problem
Strange. I was making some tests last night, talking to another person using the speakerphone.
It worked just fine most of the time. Her voice was a little distorted due to the bad quality (maybe just bad equalization) of the speaker, but she told me she could hear me well. She told that even though I was speaking far from the mic and not that loud, the sound came just clear to her. The only thing she noticed was that I sounded like an answering machine .I also tested running some programs while speaking to her.. and then, coincidence or not, she heard some static for a second or two.
I also tested speaking while she was also speaking, and we both heard each other. It worked as a full-duplex.
I must say that it was late at night, so it was all silent. Except when my dog started barking, he was far away at the yard, and she heard him too.
I used it some days ago while driving, and she couldn't hear me. I had the radio on, and there was traffic sound and stuff. I had to turn the speaker off because I was driving and I was in a hurry, so I couldn't test any further.
Later on, I tested it with my girlfriend when we both were in my car and I was driving. She said she could hear me, but then it started echoing due to the loudness of my speaker, and that was all we could test.
I had Microphone AGC disabled in all tests.
I have the same problem... the other person cannot hear me when i am on speaker
i have the same problem!!!
This is a serious problem it appears most of us are having with the speaker phone microphone.
Has anyone logged this problem with HTC?
It looks like a s/w update will be required to fix?
I am using with an MDA Vario III UK and it seems to be working fine, I have not had any problems even after installing software or by having AVG on or off.
There is a problem if both parties speak at the same time where either person may not hear the other, I think that is to do with a duplex problem mentioned earlier in the thread.
It appears a number of people have the problem and a number do not. It may be software version related.
I am using the following software on an AT&T Tilt:
ROM version: 1.57.502.2
Radio version: 22.45.88.07H
We need to find a pattern with the problem, Can others share what software they are running and if they have the microphone problem?
Speaker problem is software
I can confirm that it is a software problem. When I recieved my MDA Vario III didn't had the speaker problem but as soon as I flashed my device with either the kaiser or tytn II rom the problem occured. Don't know how to solve it...

[Q] Microphone problems

Hi folks, I had a search but didn't find anything conclusive.
Had my Nexus One for a few months now and although it isn't my main phone I am having some issues with the microphone when I do use it.
It seems to sometimes not work and others it does. However, if I put it on loudspeaker it works all the time. From what I have gathered, there are 2 microphones that get used on the one so I could be having an issue with one not working?
Also when it does work, it is very quiet or soft.
Does anyone know if I need a new microphone or if there is a fix I can do without buying a new part. If a new part is needed, does anyone know somewhere on the web where I can buy one?
Thanks,
Fraser

[Q] HTC one, no sound from speakers,can't make/receive calls,

hi, tech guys and friends. I recently got my HTC one probably two months backfrom an eBay seller
here's my problem
1. no sound comes from any of the speakers.
2. when I tried to play an audio.file it says unable to.play this type of audio file
3. headphones doesn't work,no Mic even
4. when I make calls neither of the part hear their sounds,also call screen hanags
5. videeoe recording doesn't work
generally audio related actions denied to work. I don't have warranty and I am thinking what causing this problem
1. software??
not sure , as I flashed the stock firmware with RUU. and made many resets the other phone functions work properly,but sounds never come up
why it says unable to.play this type of audio file with stock player???
2. hardware??
I checked the headphone jack and and moved back and forth the headset connector, but no use , no sound comes
pls help me this is I feel serious problem to me I.don't have warranty as I purchased from eBay. and I cannot disassemble before deciding hw/sw problem. the repairability is quite on low side.
I am badly seeking for solution..i hope someone already should have faced these kinda problem and might have solved it..pls share it to me or share your experiences... thanks
This is most probably a hardware problem. If everything is stock and bla bla bla then you should complain to the seller. Send it to HTC for a check. It's usually $35 for an inspection and decide what you want to do with the phone from there.
Good luck

Aux problem

hello guys,
THE PROBLEM I AM FACING IS WHEN I CONNECT MY PHONE THROUGH AUX CABLE IN MY CAR THE SOUND IS VERY POOR (DISTORTED/CRACKING).
THINGS ALREADY TRIED-
1. USED DIFFERENT AUX CABLES.
2. STEREO OF CAR IS TOTALLY FINE AND PLAYING SOUND FROM OTHER FONES FLAWLESSLY.
3. NEVER HAD SUCH PROBLEM WITH HEADPHONES.
4. CLEANED AUDIO JACK SEVERAL TIMES.
INTERESTING THING IS THAT I HAVE A GALAXY S3 ALSO AND THE SAME PROBLEM IS WITH THAT BRAND NEW SET.
I HOPE YOU WILL REVERT BACK WITH THE MOST APPROPRIATE SOLUTION.
You need a new phone or someone to repair it. For the longest time my note 2 was suffering from the listed symptoms. I tried different aux cords. Even regular headphones wouldn't work. Didn't matter much since Imma bluetooth user. I read the threads on the net and come to find out the s3 along with a few other Samsung phones suffer from this. I just got a replacement phone and problem fixed

Change the headphone jack. Part is cheap and you can get on ebay. I recommend a oem one, not a china copy.
if you are having the problem with both your phones, then it is more likely that the problem is with your car stereo.. check the settings once again..

Lumia 930 defect mic fix with hack?

Hello everyone!
Not sure if it's been posted before, but there's a relatively big batch of Lumia 930 devices that have microphones that short circuit after a while. It's heavily discussed in this topic on Windows Central and I'm also a victim of it.
What happens is that 2 of the 4 mics (mostly at the back) on the 930 suddenly don't work anymore. Therefor the device can't record any sound while filming in Windows Camera (W10M), Whatsapp, Voice recorder, etc. Those apps use only the two back microphones. The front microphones are disabled or are used to cancel noise by default. When calling, the bottom front (still working) microphone is used.
Is there a hack that could make it possible to use the other (front) microphones on the phone to record sound while filming? Like a "use all microphones" hack? Or maybe a tweak to disable noise cancellation?
I checked in several forum if there is any solution to the problem , but almost all ask to take the appliance to a technical assistance .
My phone is no longer under warranty , the repair value is too expensive (better buy a new one)
But I'm thinking about changing the microphone , I saw that there are websites selling like this user ( brittech14) on Ebay.
Anyone know if replacing the microphone solves the problem ?
Also looking for an answer to this problem if it is either possible to disable mic 3&4, force apps to use mic 1&2 instead of 3&4 or a way to fix this by disassembly.
Would really appreciate if someone knows more about fixing this issue.
Hi,
The only way to solve mics problem is replacing them. Changing the mics functionality through software hacking is impossible. Since, the Lumia 930 has two product code, RM-1087 and RM-1045 (the latter is popular), as a small chance (but risky) you can try the firmware of RM-1087 on your device (Download Links).
Having the same issue with a phone that is out of warranty, curious if there is any solution, registry edit, tweak, etc. to remap 3rd and 4th mics to the working 1 and 2...
Fortunately, some of HW issues such as mic problem are supposed to be fixed in future w10m updates, probably RS2.
does not solve problem, just replaced the microphone still does not work
