About a year and a bit ago I had a issues with Vista and my Microphones. I do a lot of stuff with the Microphone and my computer, and this was a huge issue! Why on earth could I not get the microphone to work In Vista! Within Vista, there was no way to get the microphone audio to play through the speakers. It always seemed muted. How could I un-mute the microphone?
Luckily within a few days of posting the Vista Microphone issue, hundreds of people started posting their solutions to the problem. The main issue was that the Microphone Line Monitor in the sound control panel was nowhere to be seen. Therefore, by default as Vista mutes the line, there was no way to turn it on.
If your soundcard uses the Sigmatel Audio Codec, you are in huge luck as there is a simple way to enable the Microphone on vista with a simple registry hack.
Simply go to your start menu and type in regedit and hit enter to get into the Vista Windows Registry
Next you are going to want to find the following folder:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0000\Settings\filter\SpeakerHp\
Then you're going to find the key: EnableIntSpkrMute
Change this key from 01, to 00.
Reboot Vista, and you are ready to go! Next time you go into your sound control panel, you will have the ability to un-mute, and change your microphone levels in Vista!
Hope this helps everyone out there with what I have found to be the most annoying issue in Vista out there. Who knows what made them decided to lock out the Microphone from 90% of the people out there, but at least now you can resolve the issue pretty easily!
Of course if you don't want to go into the registry to fix your Vista Microphone issue, simply download this Reg file, and run it on your machine, then reboot. Simple. Enjoy your microphone!










Hi!
I recently bought a Toshiba A200 21T with Vista Home Premium. I used to play guitar through my older laptop, a ASUS A6VM w/XP, without any problem.
I tried to do the same with my new laptop, but to my surprise I can record the sound but can't listen to it. It's driving me mad!
Apparently I am one of the unlucky to have a Realtek soundboard :(
I'm still waiting for an answer from Toshiba.
Has anyone found a solution for Realtek boards?
Thanks!

In AUDIO--->speakers--->Levels I CANNOT SEE LINE IN bar to control volume (I am sure it is mute).

EnableInputMonitor 01
If you can help me!

Hi.. well last time i could record sounds but not listen to them. I finally found the volume control an the "Mic in" was fine and the "Mic out" was mute, so I changed that and solved the problem. The issue now is that i can't find those controls anymore.

@ Pame: How did you get to see the volume control. My situation is identical. I can record, but I can't listen in real time. Can you give some pointers here. I tried everything on the other post regarding the vista microphone issue.
Thanks!

what if you have realtek integrated sound

After hours of research, I finally found a solution to the problem (I have an onboard realtek soundcard on Windows Vista 64bit). Go to Control Panel -> Sound -> Playback (NOT RECORDING) and select 'Properties' for your SPEAKERS. Then, select 'Levels' and unmute your microphone. This worked perfectly for me. Found the solution here:

Let me know if this solved anyone else's problem.

KCVI: when I follow these steps described in the pictures, I do not see any microphone level controls like those in the picture. The only controls I see are "Realtek HD audio output" and "PC beep".
I heard that Vista disables it by default somehow, and theres a way (which i do not know with Realtek) to solve this. Anybody?

I have a hp pavillion dv9618ca using vista 32. I have the same problem, mic not playing through the speaker. I tried the regedit to no avail. I did not see any phrase to enable the mic on playback or any similar phase construing the same meaning.
So far, I spent 40 hours tring to enable the mic to appear on the playback speaker level to no avail.
I need your kind assistance.
Thanks,Loseit.

My HP Pavillion DV6700 notebook is the same. Onboard Realtek sound, no option to unmute the mic and no reference to the mic in the registry. Short of upgrading to Windows 7 which has a seperate mic control there appears to be no solution to this config. (Could this be an MS plot to get people to upgrage to Win7?)
