2010 mbp mic not working

I have a mid 2010 13" macbook pro. After a logic board repair the internal mic doesn't work. The system recognises it but it picks up no sound at all. I've also tried an external mic that connects via the line in port and it suffers the same problem (recognised but no sound). Help???

Have you tried a PRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.

Internal mic not working after updating to 10.10.1

After updating to 10.10.1 (from 10.10) on my MacBook pro 2010 (15” screen) the internal mic is not working when using FaceTime (or Skype) and so the person on the other end of the video/audio call is unable to hear me. On my end there is a static/crackly sound during FaceTime (or Skype) connecting since the update which I believe is related to the mic problem (no sound input on Mac during FaceTime/Skype).
HELP!!!

I had exactly this same issue and and this workaround from Paul on another thread (Internal Mic not working for phone calls in Yosemite ) solved it :
Make sure FaceTime App is not running
Open Terminal
type sudo killall coreaudiod
Press Return
Enter your computer's admin PW

IPhone 2G voice mic not working

Has anyone come across iPhone 2G voice mic not working (not being heard by the other person) but works fine on speaker phone and bluetooth headset. It has been working fine so far and suddenly developed this problem! Any help is highly appreciated….

I had that problem with my iPhone 3G after about 5 days.
I just had Apple take a look at it.
They cleaned it out, called it and stuff.
Didn't work.
Since I didn't drop it in water and it was not my fault in any way, they gave me a brand new one.

Both internal and USB mics not working

Hi there, all. Long-time lurker, first-time poster. Starting last night, I have been having issues with microphone use on my iBook G4. Neither the internal mic nor my USB headset mic (Altec Lansing AHS302USB) are accepting input.
The internal mic's failure doesn't surprise me, as I have heard about the delicate nature of the wire connecting the internal mic from its position on the display down to the main computer. It's the USB mic that confuses me, since USB mics are what everyone seems to recommend that people use when the internal mic is on the fritz (thanks to other mics not working with Mac due to the line-in thing). Also there is the fact that I have used this headset with this computer for over a year with no significant issues until now, with both mics simultaneously failing.
There doesn't seem to be a problem with the headset's wires; I am still able to hear audio through the headphones quite well, and when I load my audio recording program (Audio In) and Sound Preferences, I can see the occasional blip of sound recognition when I move the USB adapter portion around in the port. These blips even occur when the pink microphone jack and headphones jack are unplugged from the adapter, so this suggests to me that the problem lies not with the wires, but somewhere in the USB adapter, port, or the computer itself.
I'm leaning toward the computer itself, since it just seems odd that both mics would just happen to stop working at the same time. That and the fact that audio output still works through the headset, and the USB ports work fine for other USB devices such as my external drive and iPod.
I have tried restarting, resetting the PRAM, and repairing permissions with Disk Utility. Nothing's working so far.
Does anyone have any idea what could possibly be wrong?
For reference's sake, I took a recording of the sound that results from jiggling the USB headset adapter in the port. It's very quiet, so you may need to turn up the volume a little bit to hear it. Again, these are the ONLY sounds that the mic is able to pick up currently.

iBook G4 Mac OS X (10.4.10) 768 MB RAM, 37.7 GB hard disk

Just to chime in here - I wonder if it's down to the software: I've recently updated to 10.4.10, and the internal mic seems to have stopped working.
One positive effect of the change to 10.4.10 is that my Griffin iMic no longer flips to 8-bit, 22khz recording when I plug it in.
Having said that, I really like to get my internal mic back up and running again.

Ipod mic not working

My Ipod 5th Gen mic not working

- Make sure the mic hole is clear and unobstructed. It is the little hole on the back by the camera lens(if has back camera). For the 16 GB one without the back camera the mic hole is on the top edge near the center.
- Open the Voice Memos app and see if you see movement on the VU meter needle with changes in noise level trying to be recorded
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My iPhone4 was working last 10 months till last week. it is bought from outside UAE and am Living in UAE
When I make a call , I can hear them clearly , but other side cant hear me.
I think iphone MIC is broken, but fortunately I tried recording for 10 minutes, it is working perfectly. I felt hardware working properly

After all I deleted all my content by resetting from phone and iTunes, bothways.
Now my phone content looks like new iPhone and software is 4.3.4 and
Still the MIC not working only on a phone call
Unbelievable.
I went to more than 3 apple dealers in Dubai, like istore,protech.. All they refused service for iPhone.
They dont have service for iPhone, but they selling and are autherized reseller,
My phone still under warranty.

Trust you can help me.
Thanks in Advance

X220 Internal Mic not working

I had just get a new X220 in recent days.
And I found the internal mic not working, I can not record any sound through Sound Record or Skype.
I had tried all the following methods, but the mic still can not working. Anyone cound give me some suggestion ?
1) update sound card driver to 8.32.23.2
2) Fn+F6, change between "only my voice" or "Multiple voice"
4) UnInstall source card driver and use microsoft generic driver
3) The method in http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T420-internal-mic-problem/td-p/435551/page/..., operate like :
Start -> control Panel -> Sound
Click on the "Recording" tab
Click Internal Microphone to highlight it
Click Properties
Click the "Advanced" tab
Uncheck "Enable audio enhancements"
Finally, click the "Levels" tab and turn Microphone Boost to 0dB. (if you don't do this the noise will be even louder than before).
Click apply.

hey kitewind,
welcome to the forums and since you have tested the microphone using microsoft generic drivers and i'm guessing it did not work; therefore the best action for you right now is to contact our tech support group via

EMU 0404 - audio technica ADG1 mic not working

Have a E-MU 0404, Windows 7 64 bit. Headphones and audio outs working fine. Need help with mic issue. Mic not working with this headset or my other ones. Mic input ports working, as I tested with a traditional mic with phantom power on. The headset mics do work, tested them with computer inputs.
Also bought and tried a mic preamp with no luck when plugging in the headset mic.
Why won't the 0404 pick up my gaming headphone mics, and what can I do to fix this?
Thank you in advance.

Hmm... you shouln't use those ASIO drivers which are installed by Cubase installer (ASIO MME / ASIO DirectX).
Since I don't know the version of Cubase you're using (a bit different device setup system in each version), I can only suggest you to select the "ASIO E-MU 0x0x | USB" driver (device setup) and then set up the I/Os and MIDI ports. You'll find information on how to do it by reading bundled Cubase guides (paper or PDF) ... if you don't have these guides, you'll get all downloaded from Steinberg's site:

[SOLVED]eeepc900 mic not working

Ok so ever since i switch to linux (ubuntu, about 2 years ago) from xp (which it came with) the mic has not worked. Iv tried just about ever tutorial out there to get it fixed and when i switched to arch i thought maybe it would just magically become fixed so today i went to test it out and it didnt work (i used recordmydesktop, maybe its just that program?). I tried following every document in the wiki to get it working but none of them have worked. I found this thread https://bbs.archlinux.org/viewtopic.php?id=51912 and im running the stock kernal (besides the mic everything has been GREAT!) so im not sure why mine isnt working but others are without configuring anything. So any eeepc 900 users who had the same problem and fixed it somehow?

IPhone 6 External Mic not working for Siri/Dictation

I am finding that the external mic on my iPhone 6 works for phone calls and voice memos, but does not work for Siri/Dictation. When I plug in the earbuds, they work for everything (including Siri/Dictation).
Was chatting to Apple support who had me reset all settings. I thought that worked, but realized that after a reset, Siri is off and I was talking to "Voice control" (which works). When I turned Siri back on, it does not work.
I have two questions for the community to see if you can help:
1- I have been assuming this must be a software problem since the mic does work for non-Siri access. But is that true? Is there a hardware component that Siri depends on which could be faulty here?
2- If it is software, what action should I try to address it? I have done a reset all settings already and that did not help.

Hi, everyone. I talked to Apple Genius at Apple Store last week, she said it should be a software issue and I needed to reset my iphone 6 plus as a new device and I can not use the backup restore from my iCloud, it was because the microphone bug or glitch can be in the backup also. Ok, followed her advice, erased all contents and set my iphone as a new device , the microphone worked for an hour, but went bad again. I used "voice memo" app from Apple to test the microphone. It is the best tool since it doesn't involve any provider's network and it doesn't need another person's phone to listen and test. If you can hear your voice recording clearly, then the mic works. I tested it 3-4 times a day for a few days now, half of the time the mic doesn't work. So, set as a new device isn't working. The issue is intermittent and it comes and goes as it likes, so very annoying. I carry my Apple EarPods with me in these past few days ust in case I need to make important phone calls. Will need to go back to Apple Genius this weekend for sure. Will give update after the weekend.
