Disable built-in microphone on MB Pro

I need to disable the built-in microphone on my MBPro 15" as I do not want to send sounds at all. I have been to the System Preferences SOUND panel but nothing actually disables the built-in microphone.
Does anybody know how to disable the built-in microphone???
Thanks.

How can I TEMPORARILY disable built-in microphone?

I like to record music from the web on my Touchsmart 310-1145UK (BTW this is 3 months old but HP don't recognise this model number so I can't contact customer support on-line!!! It is a 20 inch screen all-in-one PC).
I use Audacity to record, this worked fine EXCEPT that it also recorded all the noise that the built-in microphone picked up.
I found a way of disabling it, but this turned out to be permanent and there was no way of getting it back apart from a system restore.
How can I stop the micrphone, or turn it down so it doesn't work, and then easily turn it back on again?

Here is a link to your notebook's support portal. That is indeed a recognized HP product name. I searched the HP server for the link.
In the systray, right-click on the volume icon. Select Recording devices. Right-click on the microphone icone and select Disable and select OK To enable the microphone, just go back into the very same Windows that you disabled it in.
You can also access the sound Window by typing sound in the start search box. Select sound and then select the Recording tab.
Best regards,

Ho to disable (Built in) Audio card in MacBook Pro?

Ho to disable (Built in) Audio card in MacBook Pro?

Welcome to the Apple Discussions!
The only thing that I might suggest is to plug a lone Toslink miniplug adapter into the audio port. This activates the digital audio. The digital audio shuts off within a few seconds if there is no audio signal being routed through the port.

How to disable the audio track in QT Pro Movie Recording

I have a device that allows me to record DVI video (1900x1200 uncompressed) into QuickTime Pro through the Movie Recording function. It all works very well except I am trying to record video only (it's the video output of a medical device, so there is no sound). In QT pro preferences, the choices for audio input are "automatic", built-in microphone", or "line-in". I need the choice of "none" (at these files sizes I need all of the CPU's resources working on the video to improve continuity and frame rate). Does anyone know of a script to disable the audio recording portion, or how I might write one? I have never written script before, but that won't stop me from trying to learn how (or rather, launching into a prolonged period of trial and error).
I am also going to approach this by nagging the video device manufacturer, but they are more Windows- centric (they do support Mac OS X and some Linux platform so all hope is not lost). However, it would be easier if I could have more control over my own destiny, and Mac folk seem to be much more helpful.
Thanks in advance to anyone who may be able to help.

First, thanks for the quick reply.
Setting the audio option to line-in with nothing plugged in yields the same results. The device (which is essentially a continuous frame grabber) doesn't have any audio feed at all, and I think that is what is confusing QuickTime. The file I record generates one video track and several sequential audio tracks that start at roughly every 4 seconds. The movie info say that these are Big Endian Stereo L&R tracks, and that have virtually no file size to speak of. Audibly there is nothing. However, the constant "start over" with the audio is causing 2-3 second skips in the video. When the video is recording contiguously, the frame rates are on the order of 15 to 20 fps, which at 1900x1200 is fantastic for what I am doing (software training video of a Linux-based medical device; nothing cool like Snapz available for this beast).
By the way, I have tried Hack TV Carbon, hTV 0.2 and QT Broadcaster, all which will recognize the device as an input source, but not choose it. These would let me deselect the audio input. As mentioned, I am prodding the device manufacturer for help, too, so maybe they will come up with something to address this.
The other thing is that this device creates a video stream that is transferred by USB2. If it was a Firewire device, I would be all over this with iMovie HD or a HD Video recorder, and just be done with it. Apple may have to come up with some universal driver to accept USB video in since they have dropped FW on some of the new models, but this frame grabber isn't on the list as of now.
No real solution I can find to convert USB to Firewire.
Anyway, I am hoping that somehow I could get into the QT script and just disable the audio recording, like the old "save as Un-editable" script would pullout the "save" function of the QuickTime action.
Of course, dumping the audio tracks after the fact doesn't fix the video; once it's chopped up coming in...
I suspect that the real answer to this issue lies with the frame grabber manufacturer. But, I am still hopeful that the QuickTime Script writers out there (or the Terminal folks) may have something up their sleeves.
Thanks for noticin' me.

[SOLVED] HP420 and Built-in microphone don't work.

I have a trouble with my on-board microphone in my laptop (hp-420), it was working some months ago (with previous kernel) and I didn't use it for a while, after several upgrades now I tired to use it and it doesn't work. Second microphone, a jack, doesn't work either, and it's arch related, because I did some tests in windows (have dual boot) and both the built-in and jack work fine. So far I have tried testing alsa configurations, played with preferences and some other things I have read over the internet and in arch forums, but no luck at all. I may think it's kernel related but I'm not sure as I'm not an expert. Also sound works fine, it's only the built in microphone the one I can not get to work. I whish someone could help me or guide me.
So all the info I could gather about my machine and the sound

What is under the switches tab?
Oh -- By the way, that picture is over the size limit defined in the forum rules in tems of pixels, but the file size is okay. I'll let it slide. Watch the bumping as well.
If you want to post the switches tab, upload it to someplace like http://img3.imageshack.us/, copy the thumbnail (which has the link to the original) back here, and you are golden.
I had a bear of a time getting the microphone working on my HP DV4, but it does work. I'll look at the set up when I get home tonight [USA-PDT].
Sorry for the picture and the "bumping"... I have asked in irc in arch and alsa channels and no luck yet... one guy from alsa said I had to wait for the alsa-driver-1.0.24 package (currently I have alsa-driver-1.0.23) but it is weird because the microphone worked some months ago...
So here is what it is under the switches tab

Disable built-in soud

I am using an M-Audio USB device, is there a way to disable built-in soud?
This lead's to a broader question, coming from a WinXP world I got used to disabling services and such for memory and cpu intensive work, is there a Mac equivilant or an application to make it easier -http://www.litepc.com/xplite.html- is an example. Is there even a need for one.
Finally, does Dashboard need to be running all the time?
Mac Pro Mac OS X (10.4.7)

Hi,
try to use the apple menu => System => Sound: on Tab SOUNDEFFECTS and Tab OUTPUT select your M-Audio device.
You need not to disable any services on a Mac like on Windoof PC.
To disable the Dashboard you need to run OnyX which you can get from
http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html
It is a very powerful tool for a Mac.
Try it, but have a backup for save !
Hope that answer your Questions.

Built-in microphone on HP Pavilion DV6500 not working in Windows 8

Hello,
I would like to know why my built-in microphone does not work after I installed Windows 8 Pro 32-bit on my HP.
Please note that before on Windows 7 the microphone did worked.
Service tag dv6551ea
p/n: GJ013EA#B1A
Windows 8 Pro 32-bit
Thank you!

Hi ,
Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion g4-2020tx Notebook and Bluetooth not working. Here are some links that might help. I would check to make sure Bluetooth is on. It shows you how to do that under Connecting Bluetooth. A device such as computer might need to have the Discovery setting turned on. To turn on Discovery in Windows 8, from the Start screen, type Change Bluetooth to open the Search charm, and then select Change Bluetooth settings from the search results. Hope this helps. Thanks.

Soundbooth crashes when I select built-in microphone input on Mac

Every time I go into audio hardware preferences and select the built-in input or the built-in microphone options, the system crashes.
The same thing happens when I make the same selections in Premiere Pro or in After Effects, so I know it's not specifically a Soundbooth problem, but I thought maybe someone here might have an idea as to what might be going wrong and what I can do to fix it.
(I'm on a MacBook Pro, 2.66 GHz Intel Core i7, 8 GB Ram, OS 10.6.7)

You may have a corrupted webpage but you can try the following:
1 - delete the iWeb preference file, com.apple.iWeb.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iWeb's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iWeb folder (Snow Leopard and Earlier).
3 - launch iWeb and try again.
If that doesn't help continue with:
move the domain file from your Home/Library/Application Support/iWeb folder to the Desktop.
launch iWeb, create a new test site, save the new domain file and close iWeb.
go to the your Home/Library/Application Support/iWeb folder and delete the new domain file.
move your original domain file from the Desktop to the iWeb folder.
launch iWeb and try again.

Easy way to enable/disable built-in iSight?

Hello everyone!
I am trying to figure out how to enable/disable built-in iSight camera on my MacBook Pro. I do quite a bit of video conferences lately so I went out and bought a decent camera that produces a nice picture and has zoom in/out controls etc. It all nice and well but now I have a little problem - most web-based conferencing software simply uses the "default" camera, which is in my case the built-in iSight. I want to disable the iSight and make my external camera "default" one instead but I just can't figure out how to do it... Any ideas?
Cheers
Alex

Scripts like this can easily disable and enable built-in iSight:
http://techslaves.org/index.php?page=62
However, such scripts simultaneously disables ALL USB webcams when active.
Instead of disabling USB cams, select your other camera in the Flash Player settings. If you need help with settings, see Adobe Help: http://www.macromedia.com/support/documentation/en/flashplayer/help/help04.html
If necessary, you can quit your browser, launch Photo Booth or some other video app to keep your iSight busy. Minimize this app if you like, launch the browser and go to your video web site, and then check that Flash can use the camera you want.

Built-in microphone of a usb webcam in snow leopard

Hi,
This is probably a bug in snow leopard. Not sure if anyone has this issue.
I've tested 3 different webcam on this operating system. One is Logitech Quickcam Pro 9000 (Mine's called Webcam Pro 9000, according to Logitech customer service, they are exactly the same products with different name on the box.), one is Logitech Mac Fusion, and the last one is Microsoft VX-5500.
All works under snow leopard except sometimes after wake from sleep or restart, the built-in microphone doesn't work anymore.
If I go System > Preferences > Sound and choose Input, the built-in microphone shows as "Unknown Audio Devices" on all three cameras, but there's no "bars" in the sound indicator below the volume control. Sound doesn't work in Quicktime X nor any other applications, but the video works perfectly all the time.
Chi

Just want to add to this post:
The USB webcam's built-in mic that doesn't work seems to be magic mouse related. (Possible drivers or bluetooth related)
If I use a PC USB wireless mouse, after wake from sleep or a fresh restart, the usb webcam's built-in microphone works as charm. If I turn on magic mouse to wake the mac, the usb webcam's built-in microphone doesn't work. However, the video works just fine.
Another interesting discovery is that when I change the display resolution to 1080p (my mac's running on a tv), there seems to be flicker problem with the mouse pointer. The screen is just fine but the magic mouse pointer seems to jump around the screen. It doesn't happen when I use the standard PC USB wireless mouse.
Also, when the usb webcam's built-in mic stops working, the two-finger swipe function of the magic mouse doesn't work sometimes.
I'm not sure if anybody have the same issue but I hope this would help somebody troubleshooting the problem. I'm currently switching to a usb wireless mouse instead of the magic mouse and everything is now working just fine, even the built-in microphone.

Hissing Sound from built-in microphone

Hey guys, I've recently purchased and installed Logic on my iMac running on ML.
Without any external microphones or any other external hardware plugged into the computer, I'm getting a horrible hissing sound when I try recording something using the built-in microphone.
After two days spent trying to solve the issue, I've installed a very basic sound recording app (Audio Hijack Pro) and after hitting the record button I get the same sound.
I've tried lowering the built-in microphone volume in System Preferences but the problem persists. The problem is therefore not with the software but the built-in hardware...but I'm out of ideas!
Strange enough, I don't have the same issue using Garage Band
Any help please?

Go here:
http://help.apple.com/logicpro/mac/9.1.6/en/logicpro/usermanual/#chapter=2%26sec tion=0
Read "Configuring Your Audio Hardware" see if it answrs your question.
Try not to equate Logic & Garageband, while they share some of the same elements Garageband tends to set things up for you, Logic being a professional programs expects the user to know how to set the program up for their particular system.
Reading the manuals and using the online help is a must.
You don't need Audio HiJack Pro, if anything it will confuse matters.

Built in microphone problem with my hp pavillion dv6000

Hi, I was uninstalling a program on my add/remove programs list the other day and being in a hurry I accidentally clicked whatever software necessary for my built in microphone to work. I know it started with a C but I didn't see the whole title before it was uninstalled. I have windows vista and my notebook is a HP pavillion dv6000. Now when i open my sound recorder program it says " An audio recording device cannot be found". I'm almost positive whatever I clicked uninstalled my driver/software/etc. Any help would be greatly appreciated, thank you.

Hi,
I did a very similar thing and accidently disabled my internal mike. Now when I open my sound recorder, I get an error message saying "Audio recording device not found". Will be grateful if you could inform me of the solution to this problem.
Thank you.

Built in microphone not an option for Audio MIDI Setup

Hi! I am using a Macbook Pro, updated up to 10.7.5 I can't update any higher due to lack of sufficient memory. Anyway, I've been trying to use Soundflower to begin recording Minecraft videos, and upon setting it up I noticed my Audio MIDI Setup does not have the Built in Microphone option. Without it, I cannot use Soundflower. I watched videos back when 10.7.5 was the newest update and they have this option in their Audio MIDI Setup. Why don't I? Can someone help me figure this out?

Hi krk102588 - welcome to the forum!
I've just come across your post, and cannot believe that no-one replied to your issue before now!
So if you're still around......
You just click on the iMovie tool with the microphone icon on it. That opens a floating window showing audio levels etc. Click on a clip where you want the voice-over to occur, and after the 'getting ready' beeps, start talking! Simple. No need to fiddle with System Prefs/Sound, unless the Internal Microphone is not selected.

Recording device (built in microphone)

Model M645/Win7 / 64
Cannot re-activate built in microphone after selecting the minijack plug in as input device.
In Skype/ options/ no input device shown ??? same as using the 'win sound devices' none are shown.
please assist on this simple problem.

Ok, I fixed the problem, actually it was an overlook on my part. Here's what I did:
Go to Control panel/Sounds/Recording. Right-click In the blank area where it says 'no recording devices' and select 'show disabled devices' and reselect the microphone..........s... happens.
