Mic Problems

Hi Everybody,
My Magician recently developed an annoying problem and I wonder if anyone had this already:
The internal Mic occasionally goes to a very low sensitivity, i.e., when talking on the phone I have to scream so that the other person can hear me. This is also valid when recording a voicememo - on the playback I hear mostly static with a faint voice in the background.
Next, when using the headset, the voicememo records Ok but when talking on the phone, the other guy ears mostly the electromagnetic noise of the GSM (a loud "RRRRRRRRRRR").
I have noticed that this effect of the headset is started when the battery voltage goes below 3.4V and, as i connect the charger, the effect disapears.
I cannot relate the effects on the internal mic with the battery charge though; it seems to be more random....
It definitely is Hardware...but could it be solved maybe with a new battery?!
Any hunches?
Thanxs!

that is actually aproblem faced by all magician users. mine too worked just fine for firts 6 months then this annoying problem arose.
others could barely hear me.
i tried every sort of registry tweak, cleaned the mic and other thing but still nothing fruitful happened.
one fine day in an attempt to fx the internal mic myself i broke it (there is hardly any service backup for o2 devices here in New Delhi)
since then either i don't use it or use it with a bluetooth handsfree. no problems with bluetooth handsfree.

Yep, That´s right: No problem with the Bluetooth, but is just annoying to have to worry about carrying the BT device all the time and being always worried about its battery state - not to mention that I already lost one...
My guess is that the Analog-to-Digital Mic Chip is failing, or some part of the Mic circuit before that, or even the power suply to the said Chip....
That's just a lot of guessed troubleshooting to do without the knowledge of the elecronic circuit itself.
BTW, I just read your post about the mic problem - Did you have the problem as well with the wired headphones?
Thanks.

no! i don't face any problem with bundled earphones or even nokia stereo earphones or a bt handsfree even if i talk from a distance.
problem is only with internal mic.
i would suggest not to try anything yourself on the board. u may ruin ur device like me.
and yes, its annoying to carry tha bt set all the time. thats why i seldom use this devica anymore...i use it only as a mp3 player paired with sony mdr-e808 earphones and equalizer app. the sound is very crisp and punchy.

Faisal is very right buddy......it is purely jumper problem. I attached a snap of my Cell for you.......See the arrow... It is mic and we have to put the black color jumper on it.... Actually what happen with us.... we don't pay much importance to that jumper... there is a tiny whole on that jumper, put that whole on the head of mic so that our voice waves travel inside the jumper and go into mic.
It is my own experience that I put wrong side of jumper on mic and got panic three times . Thanks Faisal.....

DUH!
nooooooooooo!
i meant a pure jumper solution silly!...
the jumper solution is a quoted wire or in combination solded n jumped from the main sources or the parts in between to make a proper current flow in case of any resistance in between, loose or broken connection.
unfortunately the solution i was supposed to provide was scheduled that night is delayed due to some very sudden technical reasons. And for this i really apologize.
ill try to be as prompt as i can but the time cannot be defined so please forgive me for bringing hope and than delaying it. i know exactly how it feels but hey... patience can be more fruitful
Be Good! Be Well!

You are right Faisal......... but I told everything which I demonstrated...... And I solved the problem.... It can be possible that other people also did the same mistake which I did.... They can check their mic cover, as long as you can’t provide them any solution. Right??

For the main problem of the buzz noise when calling: I had it too. And it became gradually louder, more louder. And then (it became REALLY insopportable: when in call even the main speaker emitted that noise, and considerably loud) my phone resetted. It decided to not woken up unless I took the Sim out, and that was the end of my phone (the "phone" part: I used it as an expensive mp3 for quite a while). The noise was so loud that also attempting to connect to the carrier caused soft reset. Searching around I discovered that noise to be related to RF leakage.. you have been warned folks

Clicking noise though device is muted?

I noticed that even though the phone is muted and all sounds are off, sometimes there is a clicking noise coming from the speaker when I press buttons that would normally make a noise IF the phone wasn't muted. Is that common?

I've noticed this too, it seems to be a very quiet clicking sound though, and its kind of intermittent, it only happens every 3 or 4 clicks.

Yes, thats correct!

Have you been able to find a fix?
I first commented on this issue on the official CM10.1 thread but realized it was off-topic to do so.
For me, turning off click sounds in Settings fixes the issue although if you put it on Sound or Vibrant mode, you won't be able to hearing any clicks

Im having this issue as well, anyone been able to find a fix ? anyone using a custom rom that makes this go away ?

Me too. Both N4s.
[LG NEXUS⁴] [CARBON] [MATR1X]

i have it too.
and thing that comes to my mind. as you all know speaker on N4 is constantly buzzing (due to bad electric isolation or smth like that)
so could it be that touching the device makes some kind of electrical interference (i dont know how to express what i mean) and we hear it through the speaker ?

I had this on my previous android device (LG P990). I think it's just a software bug on ALSA.

ALSA ?

[Q] Headphones not working????

Whenever I plugin my headphones, only the right side works. At first, I thought it was a problem with my headphones, but it's all headphones and roms no matter what I do. What should I do?

@aaronfrickinaustin As far as I hear I think that there's something with your headphone port(or how it's called... I forgot it.) where you plug in your headphones. See or there is something inside maybe and or dirt came in if so clean it.

It's called a socket or a jack, FYI. It's possible it's damaged, but I bet there's just some obstruction in the jack or such. Also, make sure the headphones are plugged all the way in!

Nothing's working, if anything, the issue's getting worse

I assume you looked inside to make sure there was no obstruction? If not, I'm guessing your jack is failing. You can look for a bluetooth audio adapter I suppose, as I assume you're device is out of warranty.

Well, it's completely gone, now I can't get audio out of anything :/
I guess I have to replace it now, sucks. :crying:

I have the exact same problem. My headphone doesn't work. Only the right one. First I experienced some crackling and deep sound (distorsioned), then I fixed this issue partialy with the Volume Boost Mod (flashed version) from a XDA user. The right headphone works just fine but the left one doesn't.
There is no information about this problem right now. It begun when I flashed CloudyG3 I think, but also I flashed the baseband for my modelo, I don't know if this has to do whit this
Please anyone can help me?
Thanks in advance.

Does anyone think this would work???

Microphone Broken? D801

Hello,
I have an issue with my microphone where I need to yell into it for it to have any volume at all. This behavior appears in Google Now, during phone calls, and with the Screen Recorder app (affects everywhere).
Reading a kernel thread in Android Development, I saw tons of people talking about gain and settings for the microphone, so for 3 months I chalked it up to a kernel issue in the CM nightlies I was using. Yelling into my phone in public so people could hear me haha
Since the official T-Mobile Lollipop ota came out, I decided to flash the KDZ from LG. This of course wiped out everything, recovery, new bootloader, even a new battery charging screen when dead. Clearly completely refreshed.
The issue persists.
Does anyone know what this could be? I had a similar issue when I was still in warranty, so I had the microphone replaced. I'm not sure if it did anything, I made a few test calls when it came back from warranty and it seemed to work (obviously on KK stock software for warranty shipment)
Please let me know! I wish I had an intuition with the G2 like I have had for several devices in the past, but I don't.
Thanks,
jcarrz1

My speaker is quite awful too. very quiet. (alarms, music, etc)
Headphones fine, normal volume too. and clear sound

May be the holes for mic is blocked with dust particles.

Would consider what he's ^^^^ saying.
Maybe worth opening the phone and cleaning out your dust from the inside out.
Especially on the bottom left where the Mic is.
Once you have it open blast the ports and speaker holes with a good amount of compressed air.
See if that makes a difference

That was it! thanks guys.
I actually used a normal staple to clean out the holes, I didn't have air or a needle handy. but it worked perfectly (I removed the back cover so I could see when they were cleaned out (by shining a light) and so that i wouldn't poke anything inside).
It's amazing how a little gunk/lint in those holes made me completely inaudible.
Thanks again.

[A2017G] Bottom speaker louder than top speaker

STILL NOT FIXED
I have rooted and unlocked my Axon 7 (A2017G) and edited the mixer_paths.xml file to make the audio output louder.
But there's a little problem (and I don't know if it's because of the mixer paths edit, I don't think so)
My top speaker sounds a lot more dull than my bottom speaker. My bottom speakers seem to be louder too.
How to check this? And are there more people experiencing this?
Thanks in advance.

Did not do anything to my A2017G, but I find that my top speaker is louder and "sparks" when near at full volume

Some say it's dust, but I don't know how. I haven't called with this phone much.

Bump. It's everywhere. Even on LineageOS, bottom speaker is almost twice as loud :/ It can't be dust.

BUMP
This problem is getting on my nerves. The bottom speaker is twice as loud and crispy as the top speaker, which sounds dull.
Anyone else had this and possibly fixed it?

Two questions
Did you try to reset your phone and test the speakers again?
Is there the same problem on YouTube and mp3 music files?

1. Yes I switched between roms to test modems and other stuff for ZTE.
2. Ofcourse. It's obviously the same on every output.
I guess it's just a hardware fault, but I thought maybe someone would have fix (clean it or something?)

Then I would say that this is an hardware problem indeed.

Having the same issue here, thought that other ROM will provide the fix but still zilch. Rooting the phone only meant the void of guarantee so not really good move there either.
I read somewhere online that usually bottom speaker is the one to go out first and that global version has the speakers a lot different then American and Chinese version). Any other possible fixes before replacing it? And where to find the replacement too?
Update: it should be software related since the sound in earphones has the same problem - only inverted. Which means there should be a tweak in binary or something?

I'm willing to pay to whoever makes this problem disappear. I'm beyond the point of helplessness here...

Fixed!
Fixed the issue finally! ??
Go to:
- settings
- advanced settings
- accessibility
- mono speaker output.
For the last trick to work, just try to disable it, then enable it and restart the device. Disable it again when device rebooted. Worked as a charm for me! So I'll be saving me some money ???

Omg! This problem was bugging me since day 1, but could not find any solution to this... But I've tried what you said and it works wonders! Can't believe I can now finally listen to music the way it was intented, since having a speaker with lower volume on a stereo setup is very annoying. Thank you very much for sharing the solution with us!
