DV4-1435dx Windows 7 Internal Microphone not working

I upgraded to a professional version of windows 7. My internal microphone has stopped working. I can still video chat but no one cane hear my voice. When I go into device manager, under Sound Video and game controllers it shows 2 high definition audo devices with no error messages next to them. Only question mark I have in device manager is under other devices and known as unknown device. When I click on properties it says location is pci bus.
Does anyone have a solution for these issues? I'd love to have my onboard microphone to work. Thanks for your help.

Internal Microphone not working for L505D-S5983 (PLEASE HELP!)

Hi,
I can't seem to get my internal microphone to work. I have enabled it under Sound->Manage Audio Devices
->Recording tab. However the green vertical bar does not detect any voice. After setting the Microphone boost to +40dB, it detected some noise (since it has some green light) but I realized it wasn't detecting my voice. Since this did not work, I re-set the Microphone boost to only +10dB. I only have one internal microphone and no external microphone.
I have seen many postings on internal microphones not working on Toshiba laptops but couldn't find a solution to mine. Can someone please help? I think it's about time that Toshiba fix this issue after the countless complaints.
FM.

No mentions of reinstalling the sound driver. That sometimes turns on the microphone.

Internal Microphone not working with Quicktime and some other apps, yet it does for Skype.

Internal Microphone not working with Quicktime and some other apps, yet it does for Skype.
Microphone works fine with Quictime on another mac, so I do know how to use it. The one where it is not working (A) had an external microphone and camera attached earlier, and indeed it does work with that external microphone, but not with the internal microphone selected; and (B) had RealPlayer installed previously.
Any suggestions, please?

NB 200 internal microphone not working

I have been using my NB 200 to communicate via skype for some time and now the internal microphone has stopped working. I have managed to get it working for a brief period last night but then it stopped again when my system rebooted. It therefore appearst o be a software issue. I have tried installing up to date driver software (Realtech) and system restore but the computer says nothign has changed so it will not restore. Please advise. I am using XP as my oeprating system

I've got this problem - internal microphone was working fine up to few weeks ago when I last used it for Skype. All that's happened since then is a couple of Windows updates but now I can't get it to work.
I've tried all the things suggested in this thread:
- Updated Chicony software for webcam
- Updated Realtek software
An external microphone works OK for Skype and the voice recorder utility but doesn't work with audio/video recording using the webcam software.
A Bluetooth headset (which I know is working properly) will connect with the netbook to listen to music and works fine to listen to Skype but won't work to speak and won't work at all record or playback with the webcam software.
I've fiddled with all the control panel settings including voice settings and run all the tests.
So does this sound like a hardware problem or a software problem? If the microphone itself was damaged, why would that affect the use of an external microphone?
Any ideas would be appreciated. I'm reluctant to follow up the last suggestion in this thread about reinstalling the OS as I'm not sure why that might sort out the problem?
Thanks

Brand New TouchSmart 300 internal microphone not working.

I have been trying to get my internal microphone to work with Skype.
I have done all the tests suggested on this forum and everything says that my microphone is working!
When I record anything I get a muffled noise not anything like speech.
If I record on Windows 7 Sound Recorder the green bar stays at 25% but no sound.
Is there a simple fix as really do not want to take it back to the shop to have it sent away under warranty.

Re-install Skype, and the drivers.
Reinstall drivers from Recovery Manager or download them from your update site at http://www.support.hp.com .
You can find your PN by pressing CTRL + ALT + S.
Update skype, or reinstall it, as I'm sure the latest version is compatible with Windows 7.
After you perform these tests, please post with the results.
I have more HP devices than you'd expect.
1 HP TouchPad 32 GB with Android
2 HP Touchsmarts (310-1000z and IQ527)
2 HP Printers (J6480 and J5750)
1 Laptop (HP DV6253CL)
Have at least some experience in each of those devices, and i'll do my best to help you.
Kudos if I helped!

NB205-N210 Internal Microphone NOT Working

My internal microphone quit working on my NB-205-N210 after using an external headset (w/microphone) in the left side analog audio jacks, now I can't get the internal microphone to work again... All I get is "white noise" with the volume control set at maximum... Note: an external analog microphone + USB microphone still work...
What I've tried so-far:
I have tried both Realtek and Windows XP sound and audio device tools to make sure the microphone was not muted, the volume was turned up and selected + boost on (all where set correctly)...
Un-installing then re-installing the current Realtek HD sound drivers (several times), to no avail...
Dis-assembled the netbook to check the internal microphone, plus substituted an electret microphone element to check - no luck...
Checked microphone plug, plus re-soldered the microphone connector on motherboard - still no luck...
I could get by using an external microphone, but that's not convenient when traveling, or the point...
Hope someone can help...
Solved!

Try the steps listed in this document from HP. It has the most common solutions and steps to isolate the issue.
It is possibly a hardware issue since an external microphone works without any issue, but let me know what happens with each step of the document as that will help determine if it is a hardware issue or not.
Also, let me know the results of the steps in the Using Windows Sound Recorder to test the microphone section. If this recorded file also exhibits the same behavior, then it is definitely not any third party software causing the issue.

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

ThinkPad internal microphone not working - Windows 8.1

Hello everyone,
I'm back on this forum because I had another issue... See my first one : http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T440p-camera-not-working-windows-8-1/m-p/18...
There was a problem with the cable between the camera/microphone combo card and the daughter card. Now the camera is working properly. A technician replaced the cable.
But I realized that my internal microphone is not working. I don't remember if it worked once...
My microphone is not muted, and I reinstalled the real-teck drivers. When I try to use the "listen" option in the microphone properties, I here a sort of wideband noise (let's call it white noise).
Do you have any suggestions that might help?
Thank you very much

Internal microphone not working on my hp windows 8

Recently my internal microphone has stopped working when i use an external microphone i have no problem but since my computer is newer i have no idea how to resolve the issue im using Windows 8 on my Hp pavillion g7 notebook

Hello, I have an internal Microphone issue. I already sent it in to get it fixed and the issue is happening yet again. It just doesn't work. It used one..but there is no reason why it shouldn't I just got the PC less than 5 months ago. Its Windows8 HP Envy dv6 Notebook PC. I ran a cleaner and tells me some files may be missing or something along those lines. I'm still learning the terms and understanding. I spoke to an HP online assistant. She was a bit rude after quite some time of trying to help me understand what it was I was doing. I hope I can get some help with it.
