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,
Cartman
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.

The speaker on my I-mate appears to have "blown". Sound still comes out of it but it is a bit distorted and the volume is low. When using a plug in heatset the sound is fine; so I do not feel there is an electronic or software problem.
So.... How can I get this fixed? Are there replacement parts available?
Thanks for any help.
btw, I am in the U.S.
How to fix it...
Hi,
I experimented sort of the same problem.
It turned out that it was the speaker connectors because they where not making solid contact with the motherboard. As you can see on the walthrough, the speaker is not soldered to the motherboard, instead HTC used a spring mechanism that conntects the speaker to the motherboard when assembled. Over time, some devices tend to loose this solid contact so the speaker starts to loose it's power and eventually fail. However, there is a way to fix it yourself if you already ran out of warranty and if you like to take things apart...
Here's my walkthrough: http://forum.xda-developers.com/viewtopic.php?t=8525&highlight=
Good luck!

Re: How to fix speaker problem
This is great Rayan !! I _will_ try it and let you know.
My speaker stopped working full stop a week ago. At least the vibrating mode is fully operational but, of course, this has nothing to do with the speaker's functionality.
A colleague suggested getting a bluetooth headset for operating the phone through it, in case there is no solution to the speaker problem.
I do not know whether anyone tried this alternative but if they have, I would like to know if it worked (just to get a feeling of whether there is a workaround solution too).
Thank you Rayan.

I did it ! Success
I lost the loudspeaker-sound in my Himalya. It works using headphones. I think it may have to do with another set of headphone I connected to it, which was not original. Perhaps it put the device on permanent headphone mode. But then again it might not have anything to do with that.
Is there a Himalaya expert in Berlin - Germany who might be able to help me with it? I dread having to send it to the official reapir center, as I expect it to cost a neck and a hand.
Happened to me when I received a call whilst listening to music. I pulled the headphones out before answering the call, and then answered it. I could here them but they cvouldn't hear me. If you plug the headphones in again and remove them it solves the problem. Well it did for me anyway
I tried that. I doesn't do it. It doesn't matter what kind of sound, if Media Player file is played of phone ringing, only the headphones work. I think I need a dotor.
I have read a lot about the problem in others threads. It seems the headphone-jack can get stuck, not making a contact, which normally is being made and which turns the XDA back to speaker mode, when the headphone-jack is pulled out. Hereto:
1- What does that mean exactely? Which part is that, in what part in the on-board jack? If it had been bent out of place, is it possible to bend the part pack (at best without having to disassemble)? (I tried the ramming in and out, no go).
2- I looked at the non-original jack I had used and it is about 2 mm longer than the original. Might perhaps that explain it? Is there a part in the back that could have been bent out of place?
3- If indeed this was the problem (if the jack had been bent out of place, one way or another), would the microphone work? I can record using the dictaphone and the micophone also works during a call.
When we had himalaya's it happened to both of our devices (my wife and I had one each).
It appears the spring in the speaker can come loose. I used to bang mine (pardon the pun) on my palm and sometimes it would start to work. Then we broke the speaker protection shield, and this made it easier sometimes and hard to fix in others.
When I sold it, my friend took it apart as it was out of warranty, and as he is electrically minded, he find the dodgy bit, and soldered it to the device, and now works perfectly.
Yes! Thanks Jasjar. It worked after a bit of beating.
I found a detailed instruction of how to fix it permanently in another thread. Sounds complicated and dangerous but eventually I must do it.

Sorry for kicking the topic, but this was the solution for me. I just poked in the headphone-jack with a little stick and tataaaa... my sound is back!
Sound lost problem
Hi all,
same happen to me, the sound stoped working (on my side it had nothing to do with the phone jack).
After the modifaication which is described in this forum i had still the same problem so i solder the loud speaker directly - still same problem...
After some time i flashed the device again, now it works, so on my side it was a software problem...
The device was 3 month out of power, but i think remove the battery and if the sound appears on startup (on first boot) but later not, then flash the os and it will work ...

XDA 2 sound problem...
Hi!
Plese help me!
I have strange problem with my XDA 2.
I bough it 2 days ago. It was in O2 network.
Now when I unlocked it for my network (polish ERA-GSM) I saw that when I'm calling I cant hear anything. Person from the other sight can't hear me too..
XDA have sound becose I used media-player ando other sound stuff, thats why I think that speaker is ok. Microphone is ok too becose I can record animations with sound.
So what should I do now? ;/
Plese help...
Just for reference:
A friend of mine had this 2020, and both Speakerphone and mic were not working.
When somebody called, the ringtone DID sound.
Anyway, bluetooth handsfree worked fine.
All we did was play with the jack, using the stylus! Not even headphones...
And now it works fine!
He says he'll never put phones on it again... lol
cu around!
Looking for more Info
Hi, please help me find which points in the MDAII Motherboard can I solder to disable the headphones and get the audio and mic back to the MDA.
After a while my headphone-jack is broken from the motherboard and now I only have the pin outs in it.
The device is working perfect, and I can use bluetooth headphones. I just don't have audio in the speaker and no mic without bluetooth.
I hope someone can tell me which of the red points en the picture can I solder to disable the headphones.
I just want to do this temporally until I get a replacement spare part for it.
Thanks
EDIT: 12-12-2007
I got it. Just joining 1 and 3 and you will get audio back to the PDA disabling the headphones jack.
Thanks anyways for reading this..
Did you find out what all the mboard pins are for the jack?
I have a dodgy jack and would like to take flying leads of the mboard jack to an external (easily changed) inline jack. Does any know what the 1 to 6 pins correlate to. I would like to still switch the audio via the external jack. Not bothered about the mic.
TIA.
Hi Everybody,
My Magician recently developed an annoying problem and I wonder if anyone had this already:
The internal Mic occasionally goes to a very low sensitivity, i.e., when talking on the phone I have to scream so that the other person can hear me. This is also valid when recording a voicememo - on the playback I hear mostly static with a faint voice in the background.
Next, when using the headset, the voicememo records Ok but when talking on the phone, the other guy ears mostly the electromagnetic noise of the GSM (a loud "RRRRRRRRRRR").
I have noticed that this effect of the headset is started when the battery voltage goes below 3.4V and, as i connect the charger, the effect disapears.
I cannot relate the effects on the internal mic with the battery charge though; it seems to be more random....
It definitely is Hardware...but could it be solved maybe with a new battery?!
Any hunches?
Thanxs!
that is actually aproblem faced by all magician users. mine too worked just fine for firts 6 months then this annoying problem arose.
others could barely hear me.
i tried every sort of registry tweak, cleaned the mic and other thing but still nothing fruitful happened.
one fine day in an attempt to fx the internal mic myself i broke it (there is hardly any service backup for o2 devices here in New Delhi)
since then either i don't use it or use it with a bluetooth handsfree. no problems with bluetooth handsfree.
Yep, That´s right: No problem with the Bluetooth, but is just annoying to have to worry about carrying the BT device all the time and being always worried about its battery state - not to mention that I already lost one...
My guess is that the Analog-to-Digital Mic Chip is failing, or some part of the Mic circuit before that, or even the power suply to the said Chip....
That's just a lot of guessed troubleshooting to do without the knowledge of the elecronic circuit itself.
BTW, I just read your post about the mic problem - Did you have the problem as well with the wired headphones?
Thanks.

no! i don't face any problem with bundled earphones or even nokia stereo earphones or a bt handsfree even if i talk from a distance.
problem is only with internal mic.
i would suggest not to try anything yourself on the board. u may ruin ur device like me.
and yes, its annoying to carry tha bt set all the time. thats why i seldom use this devica anymore...i use it only as a mp3 player paired with sony mdr-e808 earphones and equalizer app. the sound is very crisp and punchy.

Faisal is very right buddy......it is purely jumper problem. I attached a snap of my Cell for you.......See the arrow... It is mic and we have to put the black color jumper on it.... Actually what happen with us.... we don't pay much importance to that jumper... there is a tiny whole on that jumper, put that whole on the head of mic so that our voice waves travel inside the jumper and go into mic.
It is my own experience that I put wrong side of jumper on mic and got panic three times . Thanks Faisal.....

DUH!
nooooooooooo!
i meant a pure jumper solution silly!...
the jumper solution is a quoted wire or in combination solded n jumped from the main sources or the parts in between to make a proper current flow in case of any resistance in between, loose or broken connection.
unfortunately the solution i was supposed to provide was scheduled that night is delayed due to some very sudden technical reasons. And for this i really apologize.
ill try to be as prompt as i can but the time cannot be defined so please forgive me for bringing hope and than delaying it. i know exactly how it feels but hey... patience can be more fruitful
Be Good! Be Well!

You are right Faisal......... but I told everything which I demonstrated...... And I solved the problem.... It can be possible that other people also did the same mistake which I did.... They can check their mic cover, as long as you can’t provide them any solution. Right??
For the main problem of the buzz noise when calling: I had it too. And it became gradually louder, more louder. And then (it became REALLY insopportable: when in call even the main speaker emitted that noise, and considerably loud) my phone resetted. It decided to not woken up unless I took the Sim out, and that was the end of my phone (the "phone" part: I used it as an expensive mp3 for quite a while). The noise was so loud that also attempting to connect to the carrier caused soft reset. Searching around I discovered that noise to be related to RF leakage.. you have been warned folks
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.

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.

If yes than are you using custom kernel?

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?

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.
