[Q] Help Please! Microphone Dead/Very Quiet..?

Right, here’s the situation, I replaced the screen on my HTC Desire HD a few days ago and literally the first boot since there was a Wifi notification of a ROM update also, so I did it... (Orange UK Software number 3.13.61.5) anyway, since replacing the screen / updating the ROM, the Microphone has gone ridiculously quiet when making or receiving a phone call and if I open the Voice recorder, I can barely hear my recorded voice back, and the only way people can hear me when I call them is if they put it on loudspeaker and still put the phone to their ear...
Ok so initially I thought that this might be a hardware issue as I have been in the phone, however, given the fact that I can hear some playback via voice recorder, this means that the Microphone is working..?
So after a bit more investigation, I found that if I remove the bottom panel that covers the SD Card and Sim Card slots, then Voice recorder works perfectly (but my signal drops off completely so I can't test a phone call... *Are the 2 little gold contacts to do with the antenna?*) So I have come to the conclusion that it must be software? As obviously when these 2 little gold contacts make connection with the phone again, ye it enables me to make a phone call, but wrecks the microphone...
On a side note, I have checked the little Microphone hole on that bottom panel and shoved a pin through it and it’s as clean as a whistle so it can't be a blockage of any sort...
So something is happening when the bottom panel is on the phone, those 2 gold contacts tell the phone to do something? Provide an antenna for it but in doing so almost muting the microphone at the same time..?
Any ideas on how I can fix this or where shall I start? Could this still be a hardware issue? Shall I strip the phone down again and pay special attention to a specific part? :S
Please Help!?
Thanks in advance!
Adam.

which rom are you using? if that's a stock rom, it is highly recommended that you try one of the custom ones from development section (sense 3.5 roms)

Yes, its a stock ROM that was pushed OTA... It's a friends phone, I have a HD2 so I'm very familiar with flashing roms etc... but I'm going through the custom roms section and I can't seem to be able to find a good guide as a starting point..? I see a lot about Downgrading? and S-Off..? (Does that mean Signature Off?)
Thanks very much for the reply though!

Ok... I've flashed a custom ROM now, and a different radio '[ROM] Android Revolution HD 7.0.3 | High Quality & Performance | O/C | Legendary' is the rom I used...
Exactly the same... It's as if the microphone level is right down when the phone has signal/network as if I shout the voice recorder picks stuff up then...
Is there an App I can use to tweak the gain or something on the Mic levels?
I've had the phone in bits again and cleaned out everywhere, theres no dust build up or anything of the sort so I'm sure its not hardware related... but then if the ROM is completely different then it can't be software either can it..? :S
Cheers, Adam.

I'm no expert on electricity and all that but can it be possible that the power input onto the mic is being too low so that it is not functioning properly due to a newer screen sucking up a higher power? but then you mentioned that by removing those plates, it works fine...
I couldn't come across a fix as it seems that not many people had this problem so it seems that it is more of a hardware problem but i'll post asap i find something
EDIT: maybe this

Thanks for the reply! I can't understand what it could be... I have figured out though that if I hold the phone horizontally in front of my mouth and talk then it works... so I'm completely stumped as to what it could be...
Is there no way I can edit some sensitivity figure somewhere? :S
Cheers, Adam.

Hi All
I have had the same issue with no mic imput when calling someone on a HTC Desire 500 phone.
My problem started when I paired a plantronics bluetooth hands free device to my phone and started to use it.
While using the PK100 device all was perfect and no issues, but when I turned off the hands free device I now have the same issue no one can her me through the phone mic, no sound at all. I believe this issue is both software and hardware the software needs to switch the hardware (mic) on and off
It is as if the mic has been switched off by the (PK100) bluetooth hands free but the software on the phone is not re-enabling the phone mic so now I am in a situation where i can only use my phone via a diferent mic headphones or PK100 hands free.
I can also add that while in a call I have the option to switch from the hands free on the phone, or to use the phone or to use the PK100 from an in call option all works ok but the mic on the phone will not reactivate. this seems to be an issue with the software not activating the mic.
If anyone has any idea I would like to here...

Galaxy Nexus speaker - no sound

I have a really strange problem - my phones speaker has stopped playing all notification sounds and ringtones, but the earpiece speaker is still functioning fine. I've tried almost everything but it doesn't seem to fix it. I've tried:
-Reflashing the image from Google official
-Flashing a non-official image
-Wiping and flashing the Google image
-Those applications that "force" sound out of the speaker in case a headset is in.
Has anyone here had any similar issues and any success resolving it?

In a call, does loudspeaker work?
I had the opposite problem. My earpiece wouldn't work, but my loudspeaker would. Sent back to where i got it from, they deemed to faulty and sent out a replacement.

Nope - it thinks it is on the loudspeaker but there is just silence. Pity, the warranty has recently run out for me! I might have to crack it open and make sure nothing is loose.

You may need a replacement then as it sounds like you've tried all other attempts, just had a look on ebay and they are fairly cheap anywhere from $10-20 for a replacement speaker.

same thing just happened to my phone. Was playing a game when the sound was cutting in and out. Noticed later that the sound from the speakerphone stopped working completely (i can still use the headpiece or headphones).
Is the speaker/vibration assembly connected by one cable? I assume if the phone still vibrates and the headphone jack works, it's just a problem with the speaker and not some kind of connection problem.

i have this problem. Fix with SoundAbout app.

Its very difficult to diagnose this problem, so rather would suggest you to take it to Service Center and get it checked could be Mic problem(Hardware issue) or you could backup your data do a factory reset and try once.

I know this is an old thread, but I just wanted to ask you whether it was a hardware problem or not and whether you fixed it or not (and how). My brother is suffering from the exact issue. The other end hears him well only when he's on speaker or using any headphones with a mic. Volume in voice recordings in WhatsApp is also very low.

same here
Hi,
I am suffering from the same issue as described here.
I belief the Note 2 has 2 microphones. During taking a call the one at the Home button is active which seems broken.
The other one on the top is active in loudspeaker mode, which still works.
In regular phone mode, the caller hears me a little if background noise supression is deactivated.
I tried several ROMs since I beliefed I must be a software issue. Now I think it just is a broken mic.
Since I changed my mid-frame I belief my warranty is gone.
Hope you are in better luck.

Nexus 5X Microphone

So here is the problem. I have tried talking to Google Support and also LG Support. Not under warranty anymore. I have heard several different people mention problems with their mics in calls, be it incoming or outgoing. I have done several things to try to fix this problem; flashing stock firmware and upgrading thru OTA's, clearing cache, rebooting every day, flashing custom roms, modifying the build.prop, opening the device and checking for physical damage. To my knowledge this phone has 3 microphones that are used for actual speaking and background noise reduction. When I opened the device everything looked ok on what I assumed were the mics (the tiny square bits soldered to the logic board at the top and the bottom). I assume these were just going bad and finally gave out on me. Has anyone had any experience getting these fixed or repaired? Is there any software based approach I can look into? I am really tired of using my speakerphone in every call. I assume I am not the only person with this problem.
If anyone can shed some light on this or help in anyway I would appreciate it
Thanks!

I would start by describing the mic issue you are experiencing during voice calls.
Haven't had any myself.

No one can hear me using the microphone, as soon as I switch to speakerphone the other party is able to hear me.

I've read mics can stop functioning if you try and clean the phone with compressed air. As far as fixing or replacing a mic I am unable to provide assistance.

Well rats. Hopefully someone can shed some light on getting this fixed. I do have some soldering experience but I don't even know how this translates via the logic board. Anyone that has more information the help would be awesome. Thank you for your time though previous posters.

I have this problem as well, but also all media volume can't be heard through the speakers. I've personally cleaned and replaced the unit and nothing works, I just have to choose speaker and start talking, else use a headset or a bluetooth mic

Same problem, no solution yet.
Think that is a software/driver/app combination bug.
When Iam in call hardly can anyone​ hear me, if I cover top mic - then im heard again (proof that bottom mic is working).
Top mic is used to cancel background noise, phone interpret your voice as background noise and volume it down. That way nobody can hear you.
When I cover top mic - no background noise detected and my voice is heard again.
Question is why top mic detect legit voice as background noise?

Same problem here. Can't use microphone normally on any sort of voice call. I have to change to speaker for people to be able to hear me. I'm not sure if I still have warranty so if it's a software problem I might be able to fix it by myself.

Pixel XL - No sound from speakers

Alright guys, I've got a problem I haven't quite dealt with before:
I've got no sound coming from my "external" phone speakers. The in-ear speaker works fine, and so does the mic. That means I can take phone calls just fine. Listening to Whatsapp voice messages is a challenge because Whatsapp uses the speakers which means the message plays with no sound, that is until I hold the phone to my face and the prox switch tells the app to play through the ear speaker. No YouTube videos or Snapchat sounds.
I looked around the forums and such but didn't find anything. I've checked all the system settings I know to check, but nothing I can find is "muting" the sound. My apps list is fairly standard. Stock rom and kernel, unlocked since day 1 but without even a recovery installed. Basically a factory phone.
What are you guys thinking? I'm happy to try basically anything. Even thinking of slapping a ROM into this beast to see what happens, although I doubt there's too much development going on for a 2yo phone...
Cheers!

Update:
I've got intermittent sound. I haven't opened the phone and have no reason to think water ingress could be the problem, but I can't think of a reason that the speakers would work intermittently. Sounds more like a hardware problem than a software problem to me. Anyone else?

It also happened to me except I didn't have any sound coming from both speaker and the earpiece. Not sure what happened though.

Well it only has one speaker. As for the others most likely hardware related.

Weirdly, I'm stuck in unreliable-sound limbo. I get sound most of the time, but speaker sound disappears occasionally with no predictability that I've found. Interestingly, If I mash or smack the bottom of the phone phone screen by the speakers, sometimes sound will come back on briefly or entirely. Weird, huh? Not sure what could be causing a connection problem. Maybe I'll open up the phone eventually and find out.
