IMac internal microphone problems

I have a recurring issue with the internal microphone in my iMac. Occasionally, it will just stop working and won't pick up any sounds. The two resolutions I've found are to either unplug and re-plug the external speakers I have connected (strange) or, when that doesn't work, to restart the computer (less strange). Has anyone had a similar problem with their iMac? Adjusting the settings in the sound control panel does nothing to make this work. It seems that this is a software problem, since it's always fixed by restarting, but of course I'd like to find some way to fix this without having to restart. Thanks.

I am encountering similar issues, looking at the sound preference pane, I can see that the microphone is showing noise, this is duplicated on a skype test call... just noise no external sound is being picked up. Steps I have taken so far are:
Zapped the PRAM
Thrown away my sound preferences
Ran software update
Restarted the iMac a few times
Another thing to note is that the microphone was working ok this morning, then the sound started to degrade and now just noise.
Thanks in advance for any help or direction to solve this!
Cheers,
Sean

Audio/Internal Microphone problems

I can't seem to record anything on my PB. I'm trying the internal microphone and an external Apple microphone and a couple of different audio programs including Quicktime. Whenever I switch back and forth from "internal microphone" to "Line in" in the system prefs, I get a momentary audio input level signal, but nowhere can I get an actual sustained audio in signal. Anything I record comes up blank.
Could my internal audio hardware be dead?
- N

I'm not sure why you're not getting a signal from you internal mic, but you can't use a regular external microphone with the Line In port. Line In requires a stonger signal than a microphione can provide, so you need to use a pre-amp to boost it.
So that could explain why the Apple external microphone isn't working, although it doesn't rule out the possibility that there's a problem with your PowerBook's audio hardware.

Pavilion G7 1365dx internal microphone problems (skype).

I just purchased this notebook and when I tried to use Skype, everything works except the other person can't hear me. Mic is enabled and not muted. Internal Mic (IDT High Definition Audio CODEC). System checked for updated drivers, system said drivers are up to date. Thank you in advance for your help.

Hello @Pistaba1975,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I have read your post on how the microphone on your notebook is enabled, but will not record any audio on Skype. I would be happy to assist you in this matter!
Are you able to record audio using a different program on your computer? Were you able to record audio from Skype in the past?
In the meantime, I recommend following the steps in this document on Resolving microphone problems (Windows 8). This should help enable the audio-in when using the microphone.
Additionally, I also suggest following this resource on Microphone Troubleshooter to ensure that your Skype software is communicating the audio being transmitted to your audio-in device.
Please re-post with the results of your troubleshooting, as well as the requested information above. I look forward to your reply!

Help - Internal Microphone Problem Toshiba Satellite M305-S4910

Hello,
I really hope someone can help me. 2 days ago I bought a Toshiba Satellite M305-S4910 after reading rave reviews on BestBuy.com. After attempting to use the internal microphone I discovered the following problem.
When I am on a video chat, it sounds like there is a lot of static on the line. As soon as I plug in a headset, the sound goes away. I called best buy for the free 14 day support and they said I have two options. Bring it in to exchange for a new laptop or PAY for a service person to come troubleshoot it for me. I have spent the last 3 days transferring files, loading programs, and now I have just about everything set up on this laptop. I do not want to go EXCHANGE it for a new one and do that all over again. I can reload software if its something simple like that. Does anyone have any ideas how I can diagnose and possibly repair myself? Part of the reason I liked this one is the built in mic and webcam since I video chat A LOT!
Thanks
Kristine

Hi,
Since that the problem goes away with the use of external mic, it is very likely that the internal mic is malfunctioning or maybe a loose wire to the mic is causing the problem. Fixing these yourself means taking the notebook apart and possibly voiding your warranty.

T410(2539) Internal Microphone problem

Hi All,
I just find out my internal microphone was not working(Skype or MSN). i updated the driver for conexant audio to version 4.95.48.50 however it still doesnt work. I am using Win7 64 bit. Please kindly advise on this issue. Thanks

Some generic advice. Look in control panel, under "sound" and see what device is listed for "recording", make sure it's enabled and says it's working. Also check in your apps, if your system has options like bluetooth, it might have it set as default, in which case you'll need ot change it to your systems internal mic, but most important, you should post this in the proper section. Your topic will be seen by more T400 series users if you post in that section. This is for older models that were discontinued at the end of 2008.
If a moderator comes by first, perhaps they will move it for you.

Internal microphone problems

Recent return of iMac for broken internal microphone

I wish I could figure out what your issue is so I could duplicate it here. I'm actually trying to get the microphone to stop working. I turned the volume on the input all the way down when I bought the machine three weeks ago, and at least once I've found it had turned itself back up to the mid point. My previous MacBook Pro did this as well, and I found I had to check regularly to make sure it wasn't on.

Internal Microphone Problem

I am the owner of a A305-S6829. When the lid is open the microphone does not function. It is necessary to barely close the lid to make it function. I think the problem is that the wire harness of the camera and the microphone is in some way broken and it make connection when the lid is closed. I know this wire harness pass through the right hinge of the lid. The situation is that i am trying to buy this wire harness but I can not find any internet site to buy them. Can someone help me with that or sugest me other solution.
Thanks!!
Solved!

I have not taken one of these apart. But, these mic cables look quite long, combined with the instructions, I hope this will help.

Imac internal router problem

We are using Bell Wimax to connect to the internet and due to their towers being down for 2 weeks, we had lost our internet connection. It is back up and running, however we no longer can connect wirelessly to the computer. I was using the imac as the router and have tried to reestablish a connection, however the other computers can't connect. They recognize and register the signal but won't join in. I have tried to reset the location and then redo the sharing, but again, it did not work.

Welcome to the Apple Discussions!
First off, the folks in the G5 forums may assist you better;
Forum : Using your iMac G5
You might make sure that your Audio MIDI Setup has not been reconfigured. I can't guarantee what is correct for a G5 PPC, just an Intel. The actual setting can be found in Apps/Utilities/Audio MIDI Setup;
1. Audio Devices pane
2. Built-in Output
3. Audio Output
Source = Internal Speakers
Format = 44100.0 Hz 2ch - 24bit

Brand new 21.5" iMac, internal microphone gives garbled speech in bootcamp

so, just bought a brand new 21.5" iMac, it is updated w/ most recent OS on both the Mac and Windows side. I was playing DDO and someone said my speech sounded like an Orc. I hit mic test and sure enough my speech sounds like i'm in a tunnel and dragged out.. it's horrible, not understandable and delayed. I've tried almost everything w/ the drivers and whatnot, but nothing seems to be working.
I really need help.

Sean,
Probably should re-post this in the Boot Camp forum. It's located at:

I've a iMac 27', summer of 2012, and my garageband doesn't record by the internal microphone, what can I do, to resolve this problem?

i've a iMac 27', summer of 2012, and my garageband doesn't record by the internal microphone, what can I do, to resolve this problem?
only for contextualize, in other softwares the microphone record correctly like quicktime, or in facetime, even photobooth. but in garage band not.
i dont know if its a problem of the software, an error of actualization, or a bad configuration. please give me a hand.
cheers.

Did you choose the mic as the input device in Garageband Preferences?

My new iMac's internal microphone is not being recognized by other applications (such as Skype or rosetta stone)?

I just bought a new iMac. I'm having trouble with the internal microphone. I went to systems preferences> sound, and checked the input levels. The computer shows recieved sound from internal microphone and a USB connected microphone. However, no one on Skype can hear me, and microphone isn't recognized while using rosetta stone. Does anyone know what could be the problem with my internal mic?

I did get an answer to my problem. It was specifically with skype and Rossetta Stone. I had to re-install the apps and then do the general upgrade. It fixed the problem. Works fine now.

My internal microphone stopped working on my imac?

My internal microphone stopped working on my imac? I only noticed when I tried to use Skype. It was fine till a recent change to hard drive after a mechanical failure and a clean reinstall. I have USB headset and it works fine, in and out. Any answers/suggestions would be much appreciated.

Check your settings in System Preferences>Audio and make sure that internal microphone is selected on the input tab.

Internal microphone not working on iMac

My Inernal microphone is not working and I have tried the usual remedies:
1.) Reset the NVRAM/PRAM by doing the Command+Option+P+R
2.) Checked the Sound Preferences to make sure the Internal microphone is selectyed, Mute is unchecked, etc...
3.) I tried to do the Apple Hardware test (AHT) but that did not work. It just booted up normally when I held down the "D" key.
4.) I don't have Skype or Garage Band operational and I am not using any external microphone.
Any suggestions? I saw a post about deleting the "plist" but I left the post and couldn't find my way back to it again.
If I jack up the Input volume all the way I do see bars registering (on and off) on the Input level scale but no amount of shouting at the microphone generates any new bars. I just had the hard drive replaced with a new Hitachi hard drive but the iMac seems to be working fine other than the internal microphone. This al started when I tried to do facetime but the other party could not hear me.
I am using Mountain Lion 10.8.2
Suggestions are welcome and thanks.

It looks like your mic has really ended its life, however that happened. The bars you describe indicate that the mic input is open (and subject to interference, but no good signal from the mic itself).
You will easily agree that any - costly - repair won't be worth it. See if you can get an inexpensive external USB mic, or one of these external USB sound "cards" that offer an analog mic input, plus a mic.
