[Q] No sound in earpiece, loudspeaker, headphones... - Defy Q&A, Help & Troubleshooting

Hello, i got a Defy with this issue, i had no sound on the earpiece (i know about the infamous case of faulty earpieces) and no sound on the loudspeaker and neither using the headphones... it could be a software problem? Everything else is working fine, there's no water damage at first sight (i haven't opened the phone yet, to check the motherboard if rust is present)... physically its in excellent condition...
Someone had this problem before? What should I do before doing exhaustive flashing / changing parts? Thank you and sorry for my english.

I-Mate speaker blown

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

replaced rear speaker. still no sound

I bought and replaced a rear speaker and installed it. I still have no sound I even restored phone back to factory. Any ideas what could be wrong? Thank you
Sounds like a hardware problem. Make sure you connected the speaker correctly.
The speaker you bought could also be bad, you could have not installed it correctly, the connector on the motherboard could be bad, it could be a software problem (flashing stock rom would tell you this), or it could be a sound card problem on the board.

No sound from loudspeaker, maybe hardware problem

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.

Galaxy s4 has no sound what so ever!

Hi guys, so I have a cricket galaxy s4 (old cricket), and it has no sound what so ever whether it be from the main speaker, ear peace, or if I put earphones into the headphone jack. The microphones don't work either when sound is gone, and I'm wondering why this is. I don't think it's a software issue because no matter if I flash to another rom I still get no sound but I may be wrong. The audio sometimes works like normal , and when the audio comes back the micrphones start working again but then it goes away if it's like shaken or something. So can you guys help me out? I'm not sure if this is some deep software problem or a hardware problem (think it might be charging port?), hopefully you guys can help out thanks.
The best way to troubleshoot this problem is to completely restore your phone to stock and then, if the problem persist, it's most likely an hardware defect or a bad contact between the motherboard and components

Lg v20 speaker problem

Hi. I have v20 and my speaker fidnt work.i can hear some noise once in awhile.i open the device and reconnect the speaker.then comnect.and agold piece accidentally broken.my question is if i replace anew microphone it should work?
I don't know it might be the motherboard contacts and not the speaker. Actually I had mine open recently and I slightly broke one of the contacts but not completely so it still works.
The pic you posted does't show the speaker contact pins .That one you see there is for something else, a ground pin or something.
Sure, if the contacts on the mobo are still high enough a speaker replacement would solve the issue. If the speaker is the problem of course - it may be the contacts are not touching the speaker properly.
I would test the speaker before buying a new one with an old earphone cable if you have one. You'd just strip the ends and place them on the speaker contacts while plugged into an audio player and see if you hear anything. Oh btw, strip off the felt grille off the speaker, it sounds way better that way.

My speaker also stopped working a few months ago. I bought a new speaker but it still doesn't work so I summer that something on the motherboard is fried. It may also have been caused by the resurrection I had to pull off using QFIL around the same time. Maybe something firmware-related.
I replace the speaker, but it still doesnt work. I guess because of the gold ribon that broke..is there any way to fix it??
Anyone??
loudspeaker not working - incoming calls not ringing
Did you solve the issue ???
I apparently have the same issue with my chinese refurbished v20
The strange thing is the audio jack for my earphones was not working (but I didn't really care because I don't need it) and now it's working ! ...
