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

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.

Hey guys, ive been using my note 3 for a long time with Temaseks CM12. yesterday everything was working perfect, until i couldnt hear any audio from the speaker. tried headphones, same for those. so I rebooted and rebooted until the players/whatsapp crashed when triyng to hear audio messsages or to make new ones. after a while i noticed some sounds like "interferrences" from the speaker, EVEN when the phone was off. (of course only with battery).
same thing with the headphone jack, tried also some speakers...
today it doesnt want to start at all. just this noises when attatching it to usb. no vibration atg all, display stays off...
I also tried debricking it with the debrick img, used 2 sd cards (2GB and 16GB) none of them worked.
the display just stays black, only the speakers are making funny noises.
No warrianty, so no support from samsung, latest rom was 9.5 or 9.7 from temasek (CM12.1)
please help mee :x its difficuklt to switch from 5.7 to 4 inches. thanks in advance and sorry for the bad language.
(P.S: i can upload a video to youtube if you want to.)
So the problem is that no matter what custom ROM I use the mic volume is incredibly low. Talking on the phone I cannot be heard at all, if I put it on loudspeaker I can be heard faintly. Same problem for any app that uses the microphone, like sound recorder, recording a video, it barely picks up any sound.
But what's strange is that everything works perfectly on on Stock. I've installed custom ROMs on this before and last used cm10 before I upgraded way back. But now the problem also exists on that CM10 ROM. Any ideas how to fix it?
Additionally I've tried disabling the google now search listening (which fixed the same problem on my OPO) but does not work here. I've tried the following ROMs: CM10, CM11, CM12 all official nightlies and Crdroid 5.1.1.
Very frustrating as otherwise CM12 works perfectly and I intend to give this phone to someone!
So testing it further I found out that it works fine using google now and search. So either the internal microphone is disabled or maybe noise cancelling is messed up.
hi guys, first I can not write in English, I am using a translator, I am Brazilian (unfortunately)
My problem is the following:
I updated my Galaxy S4 i9500 for CM13 6.0.1 Optimized
It worked okay, just a few bugs in the camera, but my biggest problem is being in the microphone volume is very low, and this problem had in my old update that was the lollipop, but in Lollipop I activated Speakerphone and wore it well
Now the CM13 to the speaker the audio goes down, WhatsApp recordings come down
I've been looking at that mixer_patch.xml file, but do not know where I can try to change some value there to see if I can solve my problem
I hope you can help me in this
Excuse my English, I hope it is understandable
Thank you
It's not that the volume is very low, mic volume is fine, it's just that any mm/lp rom that's not tw uses the second mic (the one on the upper side of the phone) instead of the first mic. In calls everything works fine, but in voice recording apps like ok google or whatsapp is not.
So then, how to fix the mic problem? Is there any way to switch the first and second mic using a kind of config maybe?
Hi, thanks for visiting the topic. The problem was discovered when i installing this ROM, in fact clean LOS 14.1
He was stable, but when checking the microphone (in the dialer, voice recorder and video recording) it turned out that only the top microphone works (the S5 has two microphones - bottom and top), and the bottom one either does not work or works very poorly. So, when returning to the official firmware 6.0.1, it turned out that the top microphone should work as a noise maker, and the bottom one should work as the main one. In LOS, I understand it turned out the opposite. How can I reassign microphones or can I get drivers from the drain or can I edit some configuration files? Thanks.:silly:
