Hi,
Since my Hermes fell off the table people keep complaining that they have problems hearing my voice while talking on the phone. They say the volume of my voice is too low. When using a headset everything's fine.
I've never had a problem like that, nevertheless I dismantled the Hermes to see if there was anything wrong with the microphone after the fall, but it seemed ok.
I also recorded my own voice using the voice recorder in WM6 to test the microphone and strangely enough my voice sounds pretty loud and clear to me.
After some googling I found that many people seem to have a problem with their voice barely being heard by other people on the phone.
Solutions I could not find and I do not understand why that problem has occurred after the Hermes fell down, as it seems to be software-related (otherwise my mic-test would have resulted in a low-volume recording, which it did not).
Has anyone here had that problem and found a solution?
Well, I've solved the problem, although not by the means I originally wanted to. I just did a recovery of a Backup from before the day the Hermes fell down and voila - everything works again as it should (although I still don't get it how the phone falling down can change the SOFTWARE, but hey, as long as it works).
Again we see the importance of regular backups.
I had this problem before. tried to fix it but didn't work. Flashed all sorts of roms, all didn't work. Even newly flashed roms still had this problem.
Headset is fine
but just speaking into the mic isn't.
Same as you, recording works fine too, but mic to phone just doesn't work. I am curious how did you dissasemble your phone though, do you have a manual or something?

Hi again,
Well, the problem's back again. Even after resetting the Hermes at first it worked fine, but later people complained again that my voice was too low. So it seems that the problem is first solved by resetting/backup recovery, but then reappears. Don't know how that is possible, but I fear that it is indeed hardware-related.
Has anyone any suggestions as to what I can do?
Am I right in assuming that the hole next to the one for resetting the phone is for the microphone? Because when I dismantled my Hermes the corresponding part did not look like a microphone at all. Here's a picture of what I am talking about:
Is the part where the black rubber-thingy (circled below) that easily falls off when dismantling is placed over the microphone?
As for the dismanteling, go there:
http://www.mikechannon.net/page1.html
and search for "Hermes", there are some nice guides there.
I appreciate any hints that could lead to me solving this problem.
Update:
I've been searching for corresponding Registry Entries and so far have found these:
HKEY_CURRENT_USER/Control Panel/Phone
Changing "Vol" to 65535 increased the mic volume a little bit, but it was still too low for being acceptable (I have been testing the volume by placing my Hermes next to my PC speaker while playing an audiobook at a normal volume and calling my landline as to see how it sounds).
See also here for the thread where I found this info.
I also found these two threads:
http://forum.xda-developers.com/archive/index.php/t-260171.html
http://forum.xda-developers.com/archive/index.php/t-256734.html
My Values at HKEY_LOCAL_MACHINE\SOFTWARE\HTC\AUDIOGAINx were originally at 18 and 19. I changed them first to AA and this did, or so it seemed, increase the volume more notably. Changing the Values to CC however changed little compared to AA (although this should make the mic even louder). I may be mistaken, but I even think that the quality was better with AA.
I am not familiar with the actual volume of the mic at the receiver's end, but in my opinion the volume was pretty ok. I will call a few of the people who have been complaining and see what they have to say about the volume.
Update:
I just called my brother and he said my voice was as low as before, so my modifications had no effect.
Next thing I will try is to totally disassemble my Hermes and put it back together so to check every connection that might have gone loose.
Update: Dismantled it totally (except for the screen part) - didn't help either.
Seems like there is no solution to this problem. Most likely I will have to get a replacement. This sucks.
HI
Exactly the same problem here.
(No phone audio but Note recording & Headset works fine)
Only the phone was not dropped. Just happened !
Did a reset but did'nt wok either !
Phones in great condition.
Like you though it was a Software Issue
How much was a new mic ?
Can it be economically soldered on ?
Is there no solution whatsoever ?
Please keep me updated
Many Thanks

Hi Sampler,
In the end I found no solution to my problem. Got myself a Vario III and am using that one ever since.
Please let me know if you find anything that can solve this.
Greets,

Some of these problems (I don't say all) may be caused by damage to the mini USB port and the fine wires inside it. The port has wiring related to sound both earpiece and Mic. As you know connecting a handsfree headset cuts off the Mic and earpiece, so you can see that damage to the port or bend pins inside it can cause Mic problems. This may be why sound recording is fine, but in phone mode the Mic is cut off.
I say this only to avoid the assumption that the Mic is damaged (it may be), but it can also be the port and associated wiring that causes the problem. If you are dismantling check the solder contacts around the USB port for cracks and also for bent pins in the socket.

My microphone on my S5 is not working. When I make a call I can hear the person but they can not hear me I also tried recording my voice and it didn't work, so clearly I am assuming the microphone is broken. What part do I specifically need in order to replace the microphone and have it working?
Sounds like you didn't do a search and read the existing threads on this subject. Your assumption that the mic isn't working may not be correct. You should at least try turning off the noise cancelling settings first, speaking closer to the mic, et cetera. There is also a service menu setting for microphone gain. Failing all of those items, then a warranty claim or buying the part yourself, if out of warranty.
All of these are elaborated in more detail in existing threads.

I have tried everything you have said before. If I could possibly know what specific part that is faulty so I can replace it because the warranty is expired

It would have been helpful if you had bothered to tell us up front that you had done so.
The primary microphone is part of the charging port assembly.

Ok so replacing that part should fix the problem?
I was having mic problems. Remembered a friend having issues on his S3, he used a needle to clean rubbish out of the hole on bottom of the phone. So i did the same, very thin needle only pushed in a small amount, pulled a load of fluff out. Problem solved. Two mics on s5, bottom is for using phone normally, top is for when you use in speaker mode.
Might be worth a try.

Is your phone rooted?
If yes than are you using custom kernel?
If Yes than which kernel?
Sometimes it is due to kernel.
Such problems are more s 5 s
This is probably due to the waterproof cover
I have a rooted stock G 900 a mic doesn't work but speaker does. left touch button doesn't work or light up. the device is still under warranty so we sent it back to Samsung and they wanted almost $200 to fix it whereas I am going to pay $10 for that whole board and microphone I'm fix it myself I am hoping that this will fix the problems. I am 99% sure it is because of some water damage. just a small amount of water I believe got in the charger port. check out what. I will update on this too with results. maybe a video. I have replaced glass and motherboards on many s5 but this is a really advanced repair

Seems like my S5 is doing the same thing. It started doing this just in the last few weeks, and I haven't figured out how to address the problem.
I am having the same issue as navpal above
Does anyone have any idea how to fix this frustrating problem?
I also would appreciate if solution were posted. HEre are things I have tried with no success.
I cannot even slightly be heard on other line, except when in speakerphone mode. I can hear myself on my side, so I know that the sound is being recorded by at least one microphone.
tried:
clearing system cache
factory reset
clearing out microphone with pin
Hi there.
I have (not mine) Samsung S5 in my hands
Have tried:
Safe mode
battery out of the device and back on method
cannot do factory reset - still don`t want to disturb the client about that
Can you give me picture only of the MIC,not the whole board and others?
Maybe i can try clean it.
If i try to replace the old one will that be enough for me - i attach one photo ?
How is that done at all?
Thanks in advance
Hey Guys,
Im having the same issue. My phone went underwater without the USB flap cover and now the microphone does not work.
Should I replace all USB board? or replacing only the microphone piece would solve the problem?
Also, I wasn`t able to find more threats about it, if you guys have it, please help posting here the link.
Thx
You're about a smartass aren't you
This is an old thread, but I wanted to share my solution to this. My mic audio was very weak in speakerphone mode on Galaxy S5, but was OK in normal phone mode. The S5 has 2 microphones: bottom one is for normal mode, only top one is used in speakerphone mode. On mine the top mic hole was internally plugged with some debris. After cleaning it out by carefully inserting a broken-in-half toothpick (the blunt end) and twirling it while holding phone upside down to allow dirt to fall out, my speakerphone mic audio problem has been solved. If your mic audio is OK in speakerphone but weak in normal mode, it could be the mic hole along the bottom edge that needs cleaning. Using Voice Recorder in INTERVIEWEE mode will test only the upper microphone. Other modes of Voice Recorder enable both microphones so would be less conclusive. Cleanining out the mic holes completely solved my problem, while software fixes such as unchecking noise cancellation did not make any significant difference. Hope this is helpful.

My friend you saved me.!!!! i have tried a lot of things but the cover was the problem. Without it the mic in speakermode works great now.... I think even Samsung cannot explain this.!!!
Hello guys! My loudspeaker suddenly stopped working few weeks ago. I know the cause, and I am pretty sure it is hardware related.
Here is the story:
I installed this ROM (don't think it's important). It worked fine for about a month. The sound volume was lower than MoKee or MIUI, so I started searching for some solution.
I followed a guide similar to this to boost volume, and it worked!
Although I read in the post to not set the value over 95 (to avoid damaging speakers), I decided anyway to set it to 100, because I didn't think that could happen. Sound was very loud, and I was very happy.
Next morning, alarm screamed very strong, but suddenly stopped ringing. I realized my mistake, loudspeaker is completely mute since then.
Earpiece, headphones, microphones work, everything works except loudspeaker.
I hoped so much that was software. I formatted and installed some other ROMs (MoKee, MIUI, CM12) but still no sound. Then I restored a previous MoKee backup (taken when sound worked) but no success. Unfortunately it's a hardware thing.
I bought a new loudspeaker, learnt from YouTube how to open the Note, and replaced it. Still no sound.
Then I tested both loudspeakers (the original and the one I bought) and they both emit sound when attached to an external source (jack plugged to mp3 player). So the problem is not in the loudspeaker itself!
My knowledge ends here.
How can sound stop working by simply raising a software value? But above all, how can the loudspeaker work correctly, but not when placed into the phone? Is there another component that can be damaged in abovementioned way? If so, can that component be replaced?
I hope somebody could share some knowledge to help me solve the problem, or at least point to the right direction. Thanks in advance.
Open your Phone and look if something "looks" broken and make a picture for analysing. It can be not anything but more that just one piece that's broken.

I opened it many times today, but discovered nothing wrong or weird, although I'm not an expert so maybe I simply haven't noticed.
Will post picture as soon as I manage to take photo without phone
Yeah, its like taking a selfie with your phone on your phone without mirrors, only Chuck Norris can do that
(sry for bad English, I'm from Germany)
Some photos
I resurrected my old phone and took some photos. As I said, there's apparently nothing weird, nothing that appears burned or cut.
Here three photos (full phone, upper part, lower part) the loudspeaker contacts are highlighted.
I don't expect a hint on how to fix that (although I hope so much ) because I know this forum is meant for developers/modders/those working with software. My real question is:
Why after just altering value in mixer_paths.xml my phone is now mute? Can someone describe how the sound goes from the CPU to the loudspeaker? Is there something I can do?

I did the exact same thing. I replaced the loudspeaker just like you. My sound still doesn't work. I have done a complete factory reset and tried new roms and nothing works.

Hi Guys
I have exactly the same problem with my Xiaomi Mi3. After display replacement lound speaker stopped working. While I had broken display (just the touch screen, dispay was fine) loudspeaker worked fine (I cannot switch off alarm, even shut down the phone)
I bought new speaker, but sound still doesn't work. Do you think that it is comming from CPU? It is possible but I don't think so, because everything works fine via earphones or bluetooth speaker.
Did you find any solution?

I tried many other ways, none of them worked. I ended up buying a small BT speaker and carrying always with me.
In my case I learned in the worst way that excessive software amplification can burn audio chip. I replaced EVERY replaceable part (speaker, USB/speaker lower board, main ribbon cable, maybe others I don't remember) with no success.
@tripper22 I think you have no options. If you did my same steps, sadly your sound is lost. I have not yet replaced my phone only because there was a recent increase in development, and many custom ROMs to flash, but I will probably change that phone sooner or later.
@nokovica My sound from earphones or bluetooth is working too. I remembre reading that the audio amplifier is in a separate chip.
Anyway, your problem looks like a HARDWARE issue, since you didn't played with system configuiration. This is easier to fix (if it's fixable, of course).
If you did the replacement, you could check twice if some ribbon cable went damaged. You could try turning on your phone while open (remove back panel and expose board and cables) and see if works this way. You could check with a multimeter wether some signal (albeit small) come to the buzzer. In my case I discovered that a little signal (2-5 mV peak) reached the buzzer, but wasn't enough to make a sound. Rechecking after some months revealed that even that little signal is now gone (maybe sound chip damaged further).
If someone else did the replacement (hopefully Xiaomi assistance) it's their fault, and you can usually ask for repair for free.
Mi3 Loud Speaker Problem
@nokovica
Even I am facing the same problem with my Mi3 . After screen replacement ( touch + digitizer ) My loud speaker is not working , however phone speakar and mic is working perfectly fine , even the headphones too. I also detected one of the problem with Network Signals , if last for only few seconds and then it goes off , i tried placing many sims, but no luck . Can any one in the forum provide some solution to the Network Signals ?
even I have the same problem with my redmi note 3. I just opened back case, sub-board loudspeaker and re-assembled it. I didn't touch motherboard or any flex on upper side. Loudspeaker stopped working since then. Swapped with new part but it still doesn't work. Headphones and ear piece works fine. doesn't play music on bluetooth but hands-free works on bluetooth. how could have damaged audio chip on motherboard?? I barely touch it. didn't even unscrew it.

Did you solve? I have exactly the same problem
I have faced with no audio (at all) with mi5s
couldnt call or answer (hanging phone)
speakers dont work
erarphone dont work
i flash several times the phone and reste factory it and no change.
i read somewhere thet it resolved with warming sound IC in mainboard.
have any body solution or explane to problem?
Has anyone dealt with a dead mic ?
One day out of the blue on 4.4 mic stoped working.
Installed L 5.1. beta 3 and the mic still seems dead (Calls and Google voice) HOWEVER in sound recorder the mic works (picking every single sound) ...
Further more installed the HiQ Mp3 recorder which apparently can use front and or back mic and it works in all configs .(front back and stereo)
Tried different values via engeenering mode with no luck ....
****** Apologies to all this post was misplaced in this forum *********
I guess I should replace the charging board alltogether however I am puzled that the recordings come out clean ......
Anyone with a similar experience ??
(btw sound on wired headset is fine ... bluetooth sound is broken I think due to beta since the bt headset and speaker I tried didnt work)
Phone is Jiauy S3A
Ok Results
The issue was a dead mic (low mic) or rather a near dead mic.
Replacing the mic (on the same board ) resolves the issue (note that you can use third party mics i used asamsung one)
Best test to realise where is the fault
Open the camera recorder and start recording
Close the top mic hole with your finger, start talking in the lower mic and in the end gently (very gently) blow towards the hole.
Repeat on the top hole with the lower hole closed
After that listen to the video
If there is a problem with a mic the voice might be heard but the blow will be almost inaudiable in the problematic mic.
I have exactly the same problem - mic works fine on sound recorder and on the video camera, but Google Voice Search and using the phone does not (I've tried your blow test and it's all fine). This surely cannot be a hardware fault, can it ?
I've tried updating to LL5.1 beta3, but same problem. I've fiddled with the audio settings in the engineering menu, using a variety of values, and turned off the noise reduction without any success.
Any ideas ?

Google voice was the main indicator that the mic was bad ....
Do the blow test again and try as "gentle" as possible and then compare the results, if the uper mic is louder then then mic is dead or nearly dead.
Most probable that you ll need to change your mic
Thanks for your help - can you provide a link to the replacement mic you used (or did you use one from an old phone) - and is it easy to replace ?
Unfortunately I did go to a service shop for the repair, so I dont have a model number, all I know is that he proposed two different types, one was a noname and the other one was made by samsung (so my guess is that any samsung service center can sell you one) .
The process took about half an hour, unsoldering the old mic and soldering the new and the cost was 10 euros ( around 11 USD)
Sorry I couldnt be any more helpfull on that.
I found that, after video recording with stock camera app, main mic stop working for calls. only upper mic working. you can test it with 2 phones in both hands. but I was find simple solution: many people holding phone when taking pictures so the controls are on right side. but if you turn you phone so the shutter button will be on left side, after video recording, main mic still working!!! btw. if you like to take a shoot with control button on right side, just after you finished, turn your phone for 180° and make one more shoot, just to save your main mic for calls. no reboot needed after this action. tested on many roms, KK or LP, happend with all roms and stock camera. so problem is with stock camera app and sensor that give the information to phone to disable main mic.
Well mine was definitely a hardware fault - got a replacement lower board (USB/mic/speakers) and replaced it myself - all good again.
I think i've got the answer. The lower mic is broken for some of us. When we got to the camera app and take a video and turn the phone around it will indeed change the mic and then will use the upper one (still working) in future calls. This is why you can then be heard after when you call someone, but you'll be using the upper mic and the lower mic is still broken. Once your reboot you have to redo this. I'd like to buy a new board (usb + mic) but we cannot find any on internet anymore. Except some sellers on Ebay who are selling it from 150 dollars to 900 dollars (no joke). I guess i don't have much solution except doing that trick and use the upper mic and then try not to reboot the phone.
Hi all,
I am having problems with calling since i bought my n9005 4 years back, people did not hear me speak on the other side, but when i put the phone in speaker mode the sound was just fine on receiver side.
Using different roms from stock to CM13 and miui nothing software related seemed to be the problem (tried all the things that i could find on the net and in settings).
Anyway, so I always been calling on speaker or using my huawei watch.
Now after all this time i thought lets fix it, and bought a new USB / Mic unit which i installed without success.
Since on speaker calls still works great, normal calls only cracking sound, i thought maybe its possible to redirect thru software to secondary mic on top of phone which i believe gets activated when talk on speaker phone?
Thanks in advance.
