Qtek s200 sound gone

Hello,
sound is gone on my S200. Yesterday it all worked just fine, I was listening to some music on the headphones, and this morning I tried to call my gf, and noticed that I have no sound on the device.
The phone rings when somebody is calling me, so I assume its not the speaker, at least not the one on the back.
I can't hear a thing when I call somebody and microphone doesn't seem to be working either. I haven't dropped the phone recently.
Music is only playing via the headphones, same for calls.
Any ideas? I took the back cover off and took a look at the speaker, it seems to be fine, and as I mentioned it rings when somebody calls me.
Could this be a ROM issue? Using WM 6.5

It seems its the stuck headphone socket, I managed to get it working again somehow, but I guess it needs replacing. Any ideas where could I get the whole socket for replacement?

looks like u got it fixed sorry I forgot that can also be a problem aswell with the head phone jack about replacing it am not sure sorry maybe someother member can help you with that

Hey I am having the same problem with the headphone jack.
My phone still "thinks" the headphone is plugged in even when it itsent,
so it plays notifications through the rear speaker but it wont play music and the phones mic and speaker dont work while calling.
what did you do to fix the problem?

Try connecting your headphones again and pull them out slowly, while gently applying pressure(as in bending) and rotating it. That did it for me, works fine for now.

Mic issue? (muffled in video/audio chat).

Anyone experience any issues with Nexus 10 and its mic? I tested google voice and video chat with couple different people and they all had hard time hearing me. I had to talk louder than usual or even almost scream for them to hear me. They're reporting it always sounds muffled or the audio cuts off.
The video feed is coming in fine and I know my network connection isn't an issue. Wondering if anyone else is having similar issue and whether I should contact Google for a replacement.
Thanks!
Edit: Seems like I was able to figure out the issue. I removed the back panel and tested it and the audio is coming through fine. It seems the cover isn't aligned properly over the mic hole. I contacted Google and am getting it replaced.

So does it work now? My friend has just got one and whenever he calls me on Google Hanouts, his audio works for a few seconds, then gets muffled and choppy - I can't understand him at all......

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.

My friend device redmi note 3g got same problem.. tired change with new rom.. new speaker..and factory reset that all not work..so open the case..and discovered .the problem came from cpu/chip . coz mtk chipset camera n sound came from cpu..

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.

[Question] Microphone Issues - Any ideas?

Hello everyone, I've checked the forums and I've not really seen many answers to this question as it's something that's been bugging me for a while now.
I don't know when it started, but I noticed recently after recording a video and playing back, the sound on one side is completely gone. Almost like Stereo mode has been disabled, I have determined that it is the microphone that is often used during Loudspeaker calls, I tested this by placing a call to a friend on a regular call, then a WhatsApp Call, and finally a Skype call - and each platform is having the same issue - my loudspeaker microphone is not picking up audio. Is there a fix for this? I took apart the device, cleaned thoroughly but I'm wondering if the microphone itself has become busted. If anyone has a similar issue, or has found a fix for this - could you please provide me with some information? I love my Note 3 and would love to start recording some videos again.
Thanks everyone!

First factory reset and check again. .if same it s material problem

I've Factory Reset about 10 times since this post, and attempted all kinds of different things. I can confirm that it is a definitely a hardware issue, could you recommend what to do so I can get this fixed? Again, my primary microphone works fine while making calls - it is only when I enable Loudspeaker that the other party is unable to hear me due to the "Top Microphone" on the device not working for some unknown reason. Again, I've attempted cleans, fixes etc - but the issue only occurs during loudspeaker calls and when recording video as the top microphone is used with the primary microphone for Stereo Recording.
I know the microphone still picks up some form of audio but at a very low level - as I have called a friend and enabled loudspeaker and continued on to blowing in the hole where the microphone is situated. They can hear the loud distortion created by the air, but not a voice or anything like that. I really have to shout (And I mean LOUD) if anything audio is to be picked up.

The screen does not turn off in call on speaker or headphones

Hi guys, i have an old problem but i never found out how to fix it, so When i have a call, incoming or outgoing, the screen does not turn off when i am on speaker or headphones wired or bluetooth, but only on normal use with the phone near my ear. How is yours? Is it a common issue or just for me? Thank you

Doesn't it work like this? When on phone proximity sensor works, so you don't press buttons, but on speaker or headphones sensor is not active?

No, if the phone is on my pocket the screen is active if i have the headphones connected

Nobody with this problem?

You have to check proximity sensor - search for app in play store
Which ROM do you use?

I did, the sensor is working very well. The issue is on headphones or speaker. The rom is official, rooted
