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?

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.

I am wanting in input audio to a MacBook Pro running 10.9.4. Since there is only the internal microphone as an input choice, how do I accomplish this?

Not something I've ever done, but I found a 9-year-old article from MacWorld -> http://www.macworld.com/article/1041790/tapetocd.html - that explains it a bit. Apparently the only software that you need is GarageBand and a hardware interface. Just Google "copy audio cassette to mac" and you'll get tons of hits.
Good luck,

I removed the internal microphone - how do I get it back?

OK, I did a very stupid thing. It was late at night, I was recording - something I've done many times before - but the computer is brand new (L540 ThinkPad).
I was recording through the USB port from a synthesizer with a Audio to USB interface, and the internal microphone on the ThinkPad was recording room noises along with the synth, so I went to the control panel, clicked Sound, went to the Recording Tab and removed the RealTek internal microphone from the system.
Well, like I said, that was a stupid thing to do when I could have muted it with the F4 key - but this is the first computer I've ever had with that feature so I didn't think of it. I've been using ThinkPads since the R30, I've had R40, R50 and R60 series. You know I've seen the icon there, so I should have known, but like I said, it's late, and I've been working on this song since before noon today.
So now the question is this. Since I obviously removed it from the system, is there any way to get it back?
If so, step by step how do I do that?
I googled and couldn't find the answer - perhaps I didn't use the magic search terms.
I apologize for being such a dummy, I'm not always that stupid, but on occasion I am.
I hope there is a way to get it back into the system - I'm sure it's physically there.
Thanks for any help you can offer.

I am unsure what exactly you did (which Windows version by the way?), because I think there is no option to *delete* a device from that screen (only disable).
When you right-click there, do you have a "Hide disabled devices" option? If yes, enable it and then enable the device again.
If that does not help, check device manager - if you have your microphone there, but disabled, try to re-enable it there. If you have some unknown audio device instead, reinstall the audio driver. If you have neither, the "add new hardware wizard" (hdwwiz.exe) should find it again for you - but I think it should be found again at the next reboot anyway.

How to detect the OS version and the hardware info??

Hi all, according to the project needs, I to know how to detect OS version and the hardware info.
The point is to detect client's OS version, weather Win98, 2000, XP, Vista.
I have been search the information for several days already.
But can not really found a example which returns the OS version like"Windows XP Version 2002 *****".
And also could not find the CPU type such as"Core 2 due, or pentium D".
Is there anyone have done this before?
Thanks.
The Info I need looks like the photo below.
Message Edited by EricLu on 07-21-2009 08:09 PM

Well, in fact I have the VI and also read the topics as well...... The searching tag is OS info , system info......... After reading your post, now I understand the relation between the version number and the real OS version now, tks. And another problem is, the processor type returned within the VI have only 4 type:"INTEL 386, INTEL 486, PENTIUM, Unknown".
It can not really return my CPU TYPE. For example the desktop I’m using now is a Pentium, D , 2.80G, 2.80G.. and it only returns type "Pentium". That's why I'm asking is there any other way to do this...... (( Please forgive me if you can not really know what I'm talking about in my first post, now I know how bad my english is....... )) I guess I can only try to find out the solution from the registry then... Thanks for your information and reply.

How to reinstall drivers for internal Microphone (Leopard)

My Internal microphone stopped working about the same time I installed Wirecast and Screenflow. Any ideas how I can check that the core audio drivers are installed, or just reinstall them altogether?
I am extremely technical, but not a UNIX guy, so a solid techy answer is welcome.
Thanks in advance,

Internal Microphone - not responsive, how can I fix?

Rather than spend a large sum of time at my local Apple Store (especially carrying a fifteen+ pound computer through the mall) I decided to see what I could come up with at home.
I have the Late-2006 iMac Intel Processor, and I've of course been using it for almost two years. When I got it, the microphone was working stellar, and I was able to easily video chat/conference, no hassle at all. But for a while now (and how long I have been able to cope with this is beyond me) I have found that the microphone has not been picking up much.
I did some tests, nothing really insane, just got a ruler out and tested how well it picked up noise. It easily picked up tapping when I tapped the exterior of the computer next to the mic. From about six inches away, it could pick up some loud snapping - but it could really only process one or two snaps out of four or five (with a "level" of 7/15 bars of response in the input set up window - for this,and the remainder of these tests, the audio sensitivity was set at its highest setting). From twelve inches away, it could pick up the same amount, just at a lesser volume (5/15 bars)
Then I did a bit of a speaking test. I sat in front of my computer at a normal distance (18 inches) and tried talking. Nothing picked up. I tried at 12 inches, nothing. Six inches, nothing. Less than an inch away, and with a deepened voice, it got about 3/15 bars of response.
I tried cleaning it with some compressed gas dusting solution from office max (the kind in the aluminum can that can dust keyboards,etc.) and that picked up around 13-14/15 bars - yet no improvement in the responsiveness of my internal microphone.
Please, if you know what's up, give me the heads up, so I can schedule an appointment at my Apple Store - and skip some time by giving the guy this information!
Thanks So Much, best regards!

Try this. Download onyX (free - just Google it). It's some kind of clean-up software. Click "automation" and tick all the boxes. Then "Execute". Wait some time (20 mins?) until it's all done. Restart. Your mic may well be operating now - it worked for mine!

IMac: How to use internal built-in microphone when Bose mic-headphones are plugged?

Hi there,
I use my Bose AE2 for Lync conferences in my iMac, but the problem is that, when the headphones are plugged I seem "obliged" to use their made for iPhone/Mac mic.
The problem is that, however, the sound through this Bose's mic is terrible so the others in the conference can't properly hear me. So I just want to use the internal computer's mic, and it seems not possible when the headphones are plugged.
In that situation, Sys Preferences > Sound > Input, only shows "External microphone" and "Line in".
Meaning, what normally is "Internal microphone" automatically, when plugged, turns into "External microphone" and that's it. It's not possible to use the internal mic anymore if mic headphones are plugged.
Do you know any way to workaround this?
My OS is 10.6.8 (it's work's iMac), but I'm afraid this is not different in 10.9.X.
Many thanks in advance!

Hi, I plug in the headphones set with a regular headphones jack plug. They don't go with USB.
Thanks for answering

No sound recorded on the internal microphone after SoundMAX driver update (Windows XP)

My internal microphone is not picking up sound after I upgraded my SoundMAX driver (available from the Lenovo website here) to version 5.10.1.571.* It looks like this was a problem before and was supposedly fixed in 5.10.1.5520 which is included in the version I have.
I have tested the audio through the Control Panel utility, i.e., Sounds and Audio Devices Properties - Voice - Test hardware. No dice: my voice could not be detected. I also tested via the Windows XP sound recorder utility, i.e., Accessories - Entertainment - Sound Recorder. Same result: silence.
In the Control Panel's Sounds and Audio Devices Properties, I have verified that the Default device for Audio and Voice (playback and recording) all are set to "SoundMAX HD Audio." The SoundMAX software that ships with this laptop (also called "control panel") is very scaled back. There doesn't appear to be anything interesting there to adjust.
Thanks in advance.
* I updated the driver because I was troubleshooting my original problem. My plug and play Logitech laptop speaker suddenly stopped working. Alas, that problems remains and I have created a new one.

Hello,
Here versions of the Audio Features for Windows XP driver that I was able to find:
5.10.1.5410 - download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/7ka112ww.exe
5.10.1.5520 - download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/7ka114ww.exe
5.10.1.5670 - download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/7ka113ww.exe
5.10.1.5710 - download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/7ka116ww.exe
Hopefully, one of these will work for you.

Internal microphone not working with Windows 7 RC on dv9000 (Dv9817cl)

Hi, I recently installed Windows 7 RC (64bit) on my HP dv9000 (DV9817cl) and everything seems to work apart from the internal microphones.
In the Sounds section of the hardware and sound section of control panel there is only one recording device shown "Microphone, High definition audio device, not plugged in". I take it this is the 3.5mm microphone port on the front of the notebook. There is only one driver issue showing in device manager for "Other devices>coprocessor".
The current audio driver is High Definition Audio Device microsoft v6.1.7100.0. I've tried looking for updated drivers ion the web with no luck so far.
Does anyone know where I could get an updated driver or have any suggestions to get this going?
Thanks in advance

X220 internal microphone not working

Ever since my laptop got a motherboard replacement a few weeks ago, the internal microphone has stopped working. I have installed the most recent conexant audio drivers (8.32.23.5), uninstalled and re-installed them, and uninstalled and tried using microsoft audio drivers. None of these strategies have worked. Furthermore, in the control panel -> sound -> recording tab, it shows a "docking microphone (conexant 20672 smartaudio HD)" rather than an "internal microphone". In the properties page, it also lists the "jack information" of this device to be a "LR rear panel 3.5mm jack". I think the "docking mic" device is actually supposed to be the jack for the docking station that goes with the x220 laptop, however I have never plugged the laptop into a docking station before. There is no listing for an "internal microphone" in the recording tab of the sound page.
Based on this information, would it be logical to assume there is either some hardware issue with the internal microphone itself, or that the microphone isn't plugged into the motherboard properly? If it's not plugged in correctly, how much would I have to disassemble the laptop in order to plug it back in?

Hey there hitokirix,
That sounds like it could definitely be a hardware issue, since it's not showing in the Sound Menu.
Here's the Hardware Maintenance Manual for the X220.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a60739.pdf
It'll show you how to disassemble your machine.
Also, have you tried calling Lenovo back? They might be able to assist you, depending on how long 'a few weeks' is.

[SOLVED] Internal Microphone on Acer Aspire 1410

My microphone works on Windows but not on any Linux. Its been like this for a while now and I'm tired of using Windows so I'm determined to get my microphone working on ArchLinux. Everything else is perfect... Anyway lets start.
My sound works absolutely fine, my microphone is NOT muted, I have gone through all the steps on the wiki for fixing sound/internal microphones. Yet my microphone is not working. I've tried it on a root account so its not a permission issue either. Here are some outputs, please tell me if anything else is needed to determine the problem. Though I have experience with Linux I wouldn't consider myself an expert, and I know even less about the workings of sound cards.

well I'm not really sure of anything when it comes to this stuff, and this is why I'm here.
But it wasn't working before I started blacklisting things, just followed the wiki and blacklisted stuff that were said to work.
Recently I found a thing on the wiki for Acer One laptops (not mine but similar). It was to compile the alsa-driver with --with-card=hda_intel --with-card-options=hda_codec_realtek
this seams like it should work for me because even on windows my microphone doesn't work (but my sound does) until I install the realtek driver.
But now I have a different problem, aur's alsa-driver, though I can compile it with these options, when it gets to my system it seems orphaned and useless. I don't think my system is using it. Do you know what the reason for this might be? If the compiled "alsa-driver" package will work then how do I get that package to work on my system?
I will take all the blacklists out and reinstall all the sound functionality (starting with the new "alsa-driver". If you can think of anything please tell me.
oh and fyi I believe this laptop has mono-audio, could that be a reason I have only two channels?
