Sound distortion - Mi 3 Q&A, Help & Troubleshooting

Recently, an issue cropped up on my Mi3. When I make a call, there is no audio/sound in the earpiece. If I use headphones instead, the audio goes away after a few seconds and then there is a high pitched sound. When I connect headphone to the phone, there is a weird looping sound, that subsides only when I play some sound/audio.
Has anyone else experience this issue ? Is this an hardware problem or a software one ?

You can check what problem it is. Just make backup of ur current ROM, flash other with full wipe and check. If it will be same as before then you will have to replace ur speaker or jack input I think.

[Q] Front speaker not working.

When I make a call the front speak doesn't work, there is no sound. But when I activate the back speak the sound will work from there. I've tried doing a factory reset and that didn't help. Anyone have any suggestion on fixing this?
Also when I try to play the MP3 playing through the phones speakers there's no sound. In the sound settings when adjusting the volumes it'll preview the ringtone and alert sounds but not the media ones. It looks like the sound on all apps, media and phone calls (not though the speakerphone) aren't working.

Thanks,

I found the answer, apparently I was using a skullcandy apple headphone jack that came with my ski helmet. It messes with the phone jack and makes the phone think the headphones are still plugged in.
I'm not sure how to delete the post. Please ignore it.

[Q] help !! only system sounds working

front speaker dosent work either ??
If you think all your volume settings are correct, then answer the following questions:
Can you make phone calls normally?
Yes - front speaker is OK
No - front speaker problem
Is your phone ringing normally?
Yes - rear speaker OK
No - rear speaker problem
Do you have a problem with specific app only?
Yes - check app settings (any updates lately?)
No, multiple apps problem - check your volume settings again
Your description sounds like you are having a software problem with the same app on different ROMs.

Did you try another music player?
If your front speaker is not working during a phone call, then it's broken. This issue though is not related with your app not playing music.

You are not getting more answers because you don't describe your problem well. You've been asked 3 times have you tried another music player... and your answer is? I have a feeling you are confused which speaker is "front" and which is "back". In 2 consecutive replies I got 2 completely opposite answers from you.
Front speaker is the tiny one with a little black mesh and it will never play any music. It's one and only purpose is to hear other party during a normal phone call. Rear speaker is the one under battery door. It's purpose is to play all system sounds (rings, notifications, etc), work as speakerphone during a phone call (only if speakerphone enabled) and play music when no headphones attached (if Media Volume is properly set, of course).

i know your confused
yes i did try other music players .. i have tried other stock roms . front speaker dosent work when i a phone call .. and the rear speaker works when incoming a call but when playing music it dosent work. if i go to settings and change a ringtone then the rear speaker works . and when in a phone call if i turn on the speaker it works .
hope this helps
OK, lets fight one issue at a time:
1. As I understand, your tiny front speaker never works. If it's correct, then it is broken - hardware issue, can't fix it with software updates/changes. Needs to be replaced.
2. Your back speaker plays ringtones and notifications, but not music in any player. Obviously, the speaker itself is OK, but something else prevents music to play on it. Could be two reasons:
a) software issue with the app(s) you are using or with media volume control settings (you said you checked this already)
b) since ringtones and notifications always play through rear speaker and never through headphones, your phone might think headphones are plugged in and this is why it never plays music through back speaker. I've seen similar issue with an iPhone. The cause was dirty headphone jack. Small resistance between ground and L/R contacts makes the phone think headphones are plugged in. This causes the same issue as yours - you hear the phone ringing, but you can't play music. If you hear the music normally through your headphones, than all you need to do is to clear very well the phone jack. If it doesn't help, than more "aggressive" cleaning is needed. If it was my phone I would dissemble it and clean the PCB thoroughly.
3. If nothing helps, than you need a new phone. There is no point to pay for diagnostic/repairs on a 3y old phone.

it was after i tried slimbean
i think your right maybe i will clean it will let you know
the tiny speaker worked but after slimbean it stopped and like spending 2 dyas on a stock rom everything worked great and again after slimbean its gone
SlimBean is not the cause of your problems. Like many other users here, I'm currently running SlimBean with no sound issues.
Tone sound on device is often working

I know this might sound off, and I could be wrong, but if all else fails read up on taking the phone apart and re-seat the ribbon for the rear speaker/vibration component and re-seat the connector for the headphone jack/ front speaker/ proximity sensor component.
Yes, it seems weird that the rear speaker seems to work for some things but not others but I had your exact problem after I dropped my phone. After re-seating the rear speaker ribbon my problem was fixed. I've been using it with no issues now almost a year after I did this.
The only reason I say to re-seat both is that I did push on the phone jack connector too so I suppose that could have fixed it, but I'm fairly certain that the rear speaker ribbon was my issue....What happens is the ribbon works itself out of its seat in an off center fashion so the ribbon ends up almost crooked as can be seen when you look at the printed lines used to ensure it has been inserted all the way.

[Q] Background noise on the headphones

Hi,
In the past few days I noticed that there's some background interference when I have headphones plugged in.
To make sure its not caused by badly shielded headphones I tried the stock ones that came with the phone, stock headphones of the One X and a pair of Shure SE215 IEMs, as well as my home hifi block.
All of them show the same thing: There's audible, and annoying, background noise when there's no music playing, and slightly less annoying noise in a low-volume part of a song.
Now before I send the phone in for repairs because of the (probably) faulty DAC I wanted to know whether this might be software thing (changing overall volume also changes the volume of the noise, turning beats on or off doesn't change anything) and if somebody else has/had this issue as well.
Regards,
Alex

Strange speaker issue

My mi3 is only 5days old . it's running Android 4.4
MIUI version 4.12.5(beta)
When I'm playing music from the speaker it makes a strange buzzing noise. Even the ring tone makes same kind of noise. But if I play music with power amp it's almost unnoticeable. If I turn the speaker on while on FM radio also the buzzing notice becomes unnoticeable and sound is clear. Wonder this is a hardware issue or software issue. Anybody else facing the same issue?
It was found out to be a blown out speaker. I got a replacement with the warrenty.

[Q] MAJOR audio problems!!

Hi people
So here's the issue. Yesterday I was playing music through my speakers, all was fine, then I stopped the music. Later I put my headphones in the phone but there's no sound. Then I tried through the phone speakers. Still no sound. I've tried re flashing kernel and ROM, but it's still the same. I'm guessing something has possibly fried on the main board that deals with all sound through headphones and speakers? Mic is fine though.
If anyone has had this issue before or any info I'd love to know about it.
Peace out
UPDATE: the top speaker works on calls I can hear the other person (unless this is another speaker in the grill), and I can also hear a very faint sound through headphones. I saw someone else with the same issue and someone advised to delete Google play services data, which I did, but to no avail
Very similar problem here - no speaker audio, no headset audio (I don't think I'm getting even faint sound through the headset jack), but bluetooth audio works fine. I've tried restoring from two different Nandroid backups with no luck and am now restoring back to today's nandroid.
If anyone has any info or even guesses about this, let us know...
I've already found out that this happens due to a flex cable over heating internally. Not sure which internal flex cable as there are multiple and the audio Jack and speaker flex cables don't seem to be linked. I'm taking mine to a shop
