HT1379 internal microphone is not working in macbook pro 13"

I have a macbook pro 13"(mid 2011) currently running OS X 10.8.2. My inbuilt microphone is not working. I have tried all system preference settings and even Audio MIDI setting but still not working.

Try a commercial optical drive cleaner that is available in any store where they sell cd's/dvd's.

Re: Satellite Pro L500-1PU - internal microphone does not work

I have an L500 -1PU Toshiba, running on 32 bit Windows 7,
The webcam is working wonderfully but the internal microphone is not working properly.
I had an external microphone so i hadn't noticed this problem when i got on skype, but i've recently discovered that when using the webcam the person on the other end can hear faint noises from my computer when i'm playing music or watching a video clip.
How can i solve this and get my microphone working properly such that i can control the volume and actually get full service from my otherwise decent notebook?
Thanks

Hi
Possibly this Toshiba FAQ could help you:
+Whistling sound on the Satellite L500+

Its a matter of the settings.
This issue occurs if the microphone volume in the speakers properties is enabled.
After disabling this point the issue with acoustic feedback does not appear anymore.
Hope this helps!

Recently installed Windows 7 on Pavilion dv6748us - internal microphone does not work

I have been searching the web extensively, without success, to find how to resolve this issue.
I recently installed Windows 7, 32 bit, on my wife's HP Pavilion dv6748us laptop. Now her internal microphone does not work.
Have gotten some "roadside" advice to use a Windows Vista driver; Have no idea what the driver is or how to get it.
Have found some information about uninstalling realtek audio driver and reinstalling an older version; Have no idea on this one either.
Would really appreciate a definitive answer with a positive result.
Thanks for all help.
The drivers for the laptop are located here. select Vista and Driver-audio. The Vista driver should work. You can uninstall the driver from within the Device manager. Start --> type devmgmt.msc and the device manager will open. Locate the HD audio device and right-click it and update the driver.
After that is done go to Control Panel and Sound and the recording tab up top. Check to see if the microphone is grayed out. (not grayed out means driver is properly installed). The microphone should also have a green checkmark next to it. It is now a matter of selecting the microphone then selecting Properties to enable the microphone and then test and adjust the input level. Look at the tabs (listen,levels and advanced).
Had you considered trying Windows update or the Realtec website as a drivers source?

Hi:
Looking at your system information you could have one of two possible audio cards:
Conexant HD audio or the RealTek HD Audio
The fact that you couldn't install the RealTek HD audio driver indicates to me that you don't have a RealTek audio card. Check your device manager and look at your sound card and check to make sure which audio card you have.
Here is the Vista 32 bit driver for the Conexant audio card:

Here is the Vista 32 bit driver for the Realtek audio card:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=32...
If you in fact have the Realtek audio card, I would download and install the latest, greatest HD driver directly from the RealTek site:
Accept the agreement, download and install the first one on the list. Maybe it has been updated to fix the issue you are experiencing.

I have upgraded ML but when the MBP tries to restart with the upgrade the MBP does not restart so I susapect the ML upgrade is not complete ? When you refer to 10.8.5 supplemental is this a separate upgrade ? When I connect the Thunderbolt to the MBP the Thunderbolt charges my MBP & I can play music from iTunes via the Thunderbolt.

Generally signing out and signing in (signing out and back into the Creative Cloud application ) will fix this. If it isn't resolving the issue for you, let us know what you see and we can try something else.

Internal mic not working on macbook pro

Hello,
A few days ago I was trying to use my macspeech dictate software on my new macbook pro for the first time, I had to plug in the mic it came with and it would not work. Now my internal mic will not work at all in any other programs. I made sure it was selected under system preferences but for some reason it does not pick up on any sounds. I have my computer all up to date with version 10.6.8. Does anyone know what the problem might be?
Thank you

I doubt that the update did it, My daughter Macbook has it too and it is a general update of Yosemite. But, if you can backup your files you could go to the restore partition and reinstall Yosemite. The reinstall only installs the operating system and usually does not alter any of the other files. But having a backup is always a good idea. You can start by holding down Option or Option R at startup to do the reinstall.I cannot tell you that this will fix the internal mic problem as it could be that it is defective.

Hello, iytask4me.
Thank you for visiting Apple Support Communities.
I understand that your microphone is not working. Try resetting the System Management Controller (SMC). Once this is done, test using the microphone.

External superdrive is not working on macbook pro 15 inch(2011 model) with mountain lion

Hi,
I try to install windows in my macbook pro via bootcamp, but since I installed latest osx mountain lion on it, the external superdrive doesn't work anymore( even if on the startup mode, hardware can't detect it). superdrive works on my 2009-2010 mac mini server. help!

The USB SuperDrive only works on Macs without SuperDrive, so it's not compatible with your Mac. You have to use your internal SuperDrive to install Windows

External microphone won't work on Macbook Pro

My external microphone won't work on my Macbook Pro.
My mic is an SE2200 A, and I'm pluggin that into a Behringer Eurorack UB802 (with Phantom power). This is then connected to a 1/4 inch to 3.5mm adapter so I can plug it into my Macbook Pro.
If I plug this directly into my Macbook Pro into the headphone socket (which I've been told doubles up as a mic socket), and go to Settings -> Sound -> Input, the mic does not appear on screen at all.
If I plug it into a 3.5mm to USB adapter, and plug it into a USB port on my mac, then the USB PnP Sound Device appears on the Settings -> Sound -> Input, but no sound is picked up.
Could any suggest why this isn't working?
thanks

You have to use a cable that will break out the 3.5 mm TRRS jack into mic, L, and R.
I haven't found the right wiring yet and the cables I have tried don't seem to work.
See this post: What is the wiring digram on the MacBook Pro 3.5 mm TRRS jack?

Audio not working on macbook pro

Hi,
I have a 2007 Macbook pro. I have changed battery for this laptop twice in the past 5 years. As everyone else, I experience overheating issues. Otherwise, it has been working fine.
Today, I started using the itunes store to browse tv shows, books, and music. Suddenly I heard a big rattling noise (really loud) in my mac and it was coming from the top left side (probably the fan!). I quit the applications and shut down my laptop. When I restarted the mac, I could not listen to any songs neither from my mac nor from the internet, say youtube. No audio of any sort is working in my mac right now, not even the alert sounds.
- I checked the system preferences and could not change any output controls.
- After sometime, Ive also started noticing the red light in the headphone jack. But, this red light comes on intermittently. I tried putting my headphones in and out 3-5 times, it still did not solve the issue. The light may go off, but there is still no audio from my mac.
- Everytime I restart my mac, I hear the rattling sound. I checked my hardware, repaired the disk (using the Mac OSX disk), reset SMC, PRMV settings. None of these helped.
Im worried that my fan has gone bad and this in turn has also affected my internal audio system for some reason? I would appreciate any troubleshooting tips in this regard!
Thank you!

Well, for the red light issue, cut the end off a Q tip, or clean cut a Wooden tootooth pick(NO PAPAER CLIPS OR ANY OTHER CONDUCTIVE MATERIAL) and GENTLY "massage the headphone jack,(there is a micro switch that can hang, stop at the LEAST amount of resistance). Reboot see if that helps.
Also go to system preferences>sound>output tab and make sure the mute box is not checked, set the volume slider is at least half way up, and make sure built in speakers are selected.
If this does not solve your issue, go to utilities>Audio/MIDI set up, click putput tab, and make sure source is set to built in speakers, when selected double click on the built in speakers log out and reboot.
If you have been using Garageband, launch GB and go to GB preferences>Audio/MIDI, and select from the output tab intrenal speakers.
Here's what worked for me. It's not a workaround, this acutally solved the problem and I haven't had speaker issues since.
Go to "Activity Monitor" (you can hold "Command" "Shift" and press "U" if you're on the desktop).
Locate "coreaudiod" under "All Processes"
Right click it and click on "Quit"
After several seconds, "coreaudiod" will restart on it's own and your speakers will return to normal.
I tested this by restarting to see if it was a fluke workaround. Then I turned it off and waited a day (I had things to do so the waiting a day was easy lol). Turned it on, it was fine. I put it on sleep mode, waited 10 mins. and took it off of sleep mode. It was fine. Everything went back to normal for me.
Rattling sound is a concern for me as ths not normal, I would back up eveything, as this could br a HDD on the way out, and you want to save your data.
Also, you can try a a Pram reset:
If you have a removable battery, power doen your MBP, disconnected the power adapter, remone the battery, hold the power button down for 10 seconds, reinstall battery and mag safe and booy up.
If you have a MBP that has a non removable battery, follow the folling instructios.
Power off MBP, power it back on, holding the following keys: option, command,P,R, (no commas), press these key immediatly before the start up chime ringd, continue you to hold therse keys till you hear the start up chime ring ring 2 timess amd release.
Reboot
Since you had the battery replaced, you might want to try an SMC reset if non of the above offers any help. Power down MBP, power back up, hold the following keys before the star up chime. Left key shift,control, option, contine to hold these keys till the gear stops spinning.
Rebot.
All the best, I hoe this helps.
Let me know if this worked for you

AOL mail will not work on MacBook Pro, but works on iMac

My wife has attempted to check her aol mail account online, through Safari, and every message that she opens appears as "garbage." I recently installed Snow Leopard on both of our computers. AOL mail works on my iMac, but not her Macbook Pro. Honestly, among other issues, I'm a little disappointed with Snow Leopard. Leopard was released without problems for either of us.

Did you ever find out what the problem is???
