Loudspeaker won't work! - Xiaomi Mi 4C

My phone's loudspeaker won't work but the headphones work just fine. I believe that it was caused by excessively high volume. I took the phone apart but there doesn't seem to be anything broken. My guess is that I need to purchase a replacement but not sure from where. Any recommendations or anything I should try before buying one?

What is that sound?!

While in a call I can hear a noise like a buzzing what is it? I notice if my speakers and any thing electronic is next to it makes the same buzzing noise for instance if my phone is next to it.
I'm not exactly sure why they do it, but all GSM phones do this when the radio starts going nuts, like getting a call etc.
Sprint and Verizon not so much.
It's normal though. So expect it to happen all the time.
so annoying lol
There are better quality speakers available which have shielding preventing such interference/feedback. There isn't really any way to tell though unless you've already bought them (which doesn't help).
I'm lucky my logitech Z10 speakers have never exhibited such problems.

well thanks that would help my speaker problem. Not the phone though
Well every phone will do it, so it's not really a "phone problem". It comes with the technology. But getting shielded speakers will at least remove the "annoying" aspect.
It sounds like you're saying that you hear the noise coming out of the phone's own speakers? That's not normal, even on a GSM phone.
The clicking/buzzing on other speakers, like your clockradio or whatever are normal, but if the phone itself is acting up, it's defective, or you have it near something that's causing a lot of interference.

Frontspeaker crackling

Hi!
I just got my nexus s. When Im talking to someone else on the phone, the person I'm calling sounds very crackly. The crackling appears while having the volume > 50%. If its at 50% and lower the speaker sounds just fine. Another thing I noticed is that holding my thumb onto the speaker eliminates the crackling.
I think that I'm going to return the phone. Just wanted to know if I'm the only one having that kind of trouble.
The exact description of the phone is GT-I9023FSAC NX in case some one asks.
Thanks a lot!

are you on stock? no volume config apps?
if you havent done anything to your phone yet besides calling and texting, then yeah, i think you should get your phone replaced.

Buzzing/Humming Sound

Hey All -
I ran a quick search and didn't find this problem. I wanted to document it for posterity.
My phone makes a buzzing sound. I've seen it in every ROM I've tried so far (seems to be a hardware problem).
The sound is faint, is unaffected by media volume, and goes away when wifi is turned off. The phone appears to shut off the sound hardware when sound hasn't been played for a while in order to save battery. This makes the buzzing stop. But if a notification comes in, or there is a quiet part of a song, you can totally hear it.
It exists regardless of the ROM I have installed.
The sound is like what you'd hear in an older computer with something called crosstalk. Back in the day, (and to an extent still), various components in the hardware would generate EMI and would affect the sound quality in sound cards. For example, I had an Adlib card that would buzz a little every time the hard drive would read/write to disk.
This sounds just like that.
Anyway... just vote in the poll/comment if you're having this problem. Please post to the thread if you have a solution. I'm not expecting much though. I'm pretty sure I'd basically need a new phone for this to go away.
I get a very slight buzzing in my phones, completely unaffected by wifi. Only happens with my CX300 in-ears, any open earphones i havn't heard any noticable buzzing (though have no tried any type of headphones yet). Using Voodoo sound, lowering the amplifier dB gain and putting the media volume up reduces it a touch.
I grabbed a pair of iphone earphones and the nexus s earphones to test it with some more types, no noticeable buzzing. Also, both their sound quality is appalling in comparison to cheap sennheisers.
Yeah, that's different than me. It sounds like your CX300s might be dying.
I've got some Klipsch S4i ear buds and Bose QC3s that both have the same problem. Its loud and clear enough though that I'm sure I could hear it with cheaper headphones.
I can turn the volume all the way to zero and still hear it. When I turn it up, it doesn't make it louder though, which is "nice".
I've been all over the voodoo sound settings and nothing helps.
That's a shame, your phone probably suffers a noticeable case of leakage between the components. Could this possibly be classified as a defect and be fixed/replaced under warranty?
Also, my CX300s have no hiss on a higher quality dac and it was noticeably louder on my old nokia. I guess they're just more sensitive, they are only 16 ohm after all. No drama for me
It might qualify as a defect. I'd have to bug Samsung I guess. I could see Samsung just telling me to deal with it. It doesn't make a lot of business sense to replace a $500 phone because the headphones hiss when wifi is enabled.
It would sure make me a lot happier about buying Samsung stuff in the future though.
That's really weird about your headphones. Unless the audio quality on the CX300s is far superior over the iphone/nexus s ones, I would expect them all to behave the same way. Even then, it would be very subtle. Maybe the Nexus S doesn't ground the headphone jack very well for your headphones?
You could give them a call/email and see how it works out, but you'll probably be left without a phone for a few weeks if you send it so probably not worth it for you either.
Definitely far superior in comparison, but not nearly superior earphones Possibly a grounding issue, could even be just an unlucky set of Sennheisers that i got and have always been like this. They are out and about anyway, take a good beating and have been rock solid. Hopefully soon i'll be getting a decent pair of headphones for home use, funds allowing.
My laptop does the same thing, I'm thinking it is just interference with the headphones and your phone. might also be a lose wire or something in the phone or headphones :/
I know that this is old tread, but I had the same problem and solution might help someone.
In my case, the source of the buzz was charger (poor power supply filtering in cheap switching sources). I bought some cheap car charger/dock, and whenever I plugged my phone into it I would get lots of buzzing noise. Of course, I used it every time when in car, so I did not notice correlation for a while.
Using better charger solved my problem.
If by any chance you are charging your phone while you listening to music and getting lots of buzz, try disconnecting power cable to phone and see if there is noticeable difference. If there is, you found your problem.
Thanks for letting us know grejigl. Although not the source of my particular (non) issue, i can see it helping out someone else down the road.
I'm running on battery power when it happens to me. I'm pretty sure its caused by something related to WiFi because as soon as I shut WiFi off, the buzzing is gone.

Speakerphone Mic not working but regular calls are fine

I have the OnePlus One and cracked my screen and went to a local phone repair shop to get it replaced. Since then whenever I'm on speakerphone, people can't hear me (or I sound like I'm whispering). And when I put it back on regular call-mode the mic works fine. Is there a way to reroute the mic? I feel the other mics may be damaged. I already tried going into some of the rooted settings and increasing volumes by changing the system files, and to no avail. Does anyone know of a method like that? Or am I doomed to buy an earpiece?
Thanks

Buzzing and crackling noise from speaker

So I just got CM13 up and running, everything was fine until I opened Youtube and started playing a video. When the volume is low I hear a constant buzz (something like a static sound) and some crackling noises here and there (the sound gets a little distorted too). When I max the volume I can't really tell if it's still there or not. The material that's playing overpowers the buzzes. Also it's not happening only on youtube. I hear the same noises on every app that produces sound. I tried fiddling with the included EQ in CM but no luck. Is my speaker by any chance starting to break or what is happening? This and the glorious 1.5 SOT I get from a full charge make this phone better and better >_>... Yay!
Does it happen on stock?
Hmm... I don't really know. I only noticed it today so I can't give an answer.
If the problem occurs with a stock ROM, it could be a hardware issue.
So I flashed stock and the problem is still the same. Should I replace my speaker module? I found one here, but in the title it says it is for the D820 model (I have D821). In spite of this, judging from the part number (EAB62971502) and what it showed on Encompass it should be for D821. I don't know what to say. Are the modules compatible between D820 and D821?
I have the same problem, on every rom, no matter what media is playing. Replaced speaker, didin't change anything
@aciupapa So you say it could be something else besides the speaker? That doesn't sound very good at all...

I think that it could be that some contact points on the USB flex cable (which is the part for connecting LCD, usb cable . mic and speaker) may be vroken or something :/
Won't be able to isolate the exact problem without spare parts.
Simplest solution may be to replace speaker and see what happens.
And about the part numbers and the compatibility thing I wrote previously what do you think?
I believe the parts are the same, the only difference between the 820 and 821 being the radio frequencies.
