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

    Hi,

    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:
    http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=32...
    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.

  • 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+
    http://aps2.toshiba-tro.de/kb0/TSB0402UB0001R01.htm
    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!

    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.

  • My internal microphone no longer works after loading Skype to my MacBook Pro... What to do now???

    I use my internal microphone on my MacBook Pro very often, especially in programs like GarageBand, Audacity and Photo Booth. However, yesterday after attempting to use Skype (for the very first time) my internal microphone does not work properly in any program. The only time it responds is when I tap the area directly above the microphone.
    - I've already checked the settings in System Preferences
    - I deleted all files associated with Skype
    - I've tried holding the "option + command + r + p" while starting the computer
    - I've delete the "com.apple.soundpref.plist" file in the user library
    Has anyone else encountered this problem and knows of a definite fix, or can someone at least offer any other suggestions that may work?
    Thank You!

    The only time it responds is when I tap the area directly above the microphone.
    Sounds like a hardware problem.  Take the computer to an Apple store or an AASP.  Whichever is more convenient for you.  If you have Apple Care or your computer is still under warranty, call them up and let them deal with it.

  • Internal microphone not working pavilion sleekbook 15

    So I have had this laptop now for less than a year and have had nothing but problems with it. The harddrive has failed on me about four times now and I have had to send it back to be fixed because of this each time. It just stops updating and crashes on me. I am using windows 8. So I got it back last week and I have skype Japanese lessons so I need my internal mic for this as the only other mic I have my partner uses and I do not think I should have to go out and buy another one. So anyway I get my laptop back last week and today installed skype so I could have my language lesson. When connected he said he could not hear me so I ended the call and checked all settings for sound and mic. Everything seems fine except for the grey bar which shows no green when I talk. So I checked drivers and realised I hadn't updated them since getting it back last week. I updated drivers and still would not work. I have tried it with different programmes like audacity and a few others so it is not just skype. I am not happy about this because each time I get my laptop back from repair something else is wrong with it except this time I didn't notice it till a week later. I have not tried to use my mic till today and the webcam and mic is the main reason why I bought this laptop for my japanese lessons. I am sick to death of sending it back and having to reinstall everything it tales a week literally to get everything back on. Someone please help I have tried everything that I have come across on youtube, google and even this forum and nothing is working. I am actually close to tears right now because I feel like I have been ripped off. Oh yeah forgot to mention the second time I got my laptop back my camera was not working and my friend had to fix that for me. So yeah have they done something to do or is it a software problem. I can not do a reset because I will lose everything again and it is too annoying having to put everything back on this poor excuse for a laptop and spending a week just installing stuff between work which is why it takes so long and not getting any use out of it. I have family and friends abroad that I can not even talk to now via skype or even facebook webchat. Please help!

    Thanks for the suggestion.
    I opened the Sound control panel as you suggested and the Internal Mic (IDT) is shown in the list of microphones and has a green tick ( and is already enabled in properties). It is selected as a default device. ( the icon shows a picture of the laptop indicating the microphone on the lid  not the picture of the microphone as shown in your clip)
    In the Sound control window there is a sound indicator panel to the right of the internal Mic Icon that has a green bar that moves up and down - indicating that the microphone is responding to sound.
    However it is still not working in Skype and it is the Internal Mic that is selected as the device here.
    Very frustrating as I really would like to Skype. I tried uninstalling and re-installing Skype Version 5.5.0.117 and this has not made any difference.
    Any other thoughts?

    the best way would be to copy the entire iTunes folder (not just the iTunes music or media folder) from <MacintoshHD>/users/<yourname>/music on your Mac to the external, then launch iTunes while holding the option (⌥) key, click on choose library when prompted, and select the iTunes folder on the external.
    I have pointed itunes towards external but still not working,driving me nuts!
    that tells iTunes where to put new additions to your library, not where the content currently is.

    I had to install Dell Wireless 1702 WiFi +
    Bluetooth Driver
    The wireless adapter was defined by this driver, however, the Bluetooth still has an exclamation mark in front of it, and when the Dell WLAN and Bluetooth client installation finished, a pop up message said that Windows couldn't install the device
    well, although there was a folder added in documents folder named 'Bluetooth Folder'
    Yes, the Bluetooth was named with 'Generic Bluetooth adapter' before installing 'Driver above'. However, after installing the driver above, the Bluetooth adapter named with ' Dell wireless 1702 Bluetooth v3.0". But as you see it's
    still not working will.
    The sceen shot shows the device manger before installing  Dell
    Wireless 1702 WiFi + Bluetooth Driver
    These screen shots shows the device manger after installing  Dell
    Wireless 1702 WiFi + Bluetooth Driver
    I've lit windows detect the operating program for this device on the internet, it said "Windows has detected that the operating  program of this device is up to date. As this screenshot shows.
    What should I do because nothing lift to try? If you have a look at the ninth drivers in my previous message, you will see that no other drivers for Bluetooth lift.
    Also, I have tried  to install Intel
    Centrino Wireless-N 1030 WiFi Driver 
    But I have been told that "the installation is blocked', This package of installation cannot be installed on your system' I don't know what this
    means, is it because Dell Wireless 1702 WiFi +
    Bluetooth Driver is being installed
    Could you please take some of your preciout time out to read carefully my points below to finish this problem?
    first:
    Yes, if you had a look at my first post, you would have seen that I really have downloaded and installed the drivers suitable for bluetooth, which was only Dell
    Wireless 1702 WiFi + Bluetooth Driver, which made the bluetooth recognized by Windows 7(64Bit). However, the bluetooth in the device manager still has an exclamation mark as it is shown in the device manager.
    I don't have any other drviers which can do more than the what Dell
    Wireless 1702 WiFi + Bluetooth Driver did because I have tried all the drivers listed under 'Network', exept the what are for Etherent.
    Yes, when I have tried adding the bluetooth between two laptops(Mohammad and Nasreen).  the bluetooth was added for both laptops as you see in these screenshots below:
    The Bluetooth devices of Nasreen's laptop whose bluetooth is having some problems in Device mangage.
    The Bluetooth devices of Mohammad's laptop  whosse Bluetooh is defined well in device manager.
    But there is still problem in the device managre as shown in the screenshot listed before.
    Second: (Important) That when I want to send files or recieving between two bluetooth added in either laptop, I could send them. Also, when I open the Mohammad's bluetooth added in Nansreen's laptop( screenshot
    below), I can show what is inside it.
     However, when I open the the Nasreen's bluetooth addd in Mohammad's laptop, I noticed  no reponse at all because as you see that disconnected is written in fornt "Nasreen-Pc" as this screenshot: 
    Although sometimes Nasreen-Pc gets connected as screenshot below, but I am still not able to open the Bluetooth folder of Nasreen-pc from Mohammad-pc. When trying to do that, no response is there.
    In other times, Nasreen-pc gets connected for a while, but it comes back disconnected.
    Third:: I noticed that the name of Laptop whose Bluetooth was added listed in 'My computer' for the laptop whose Bluetooth is having some problems in the device manager.(First Screen shot below)  However,
    the name of the laptop whose Bluetooth is having problems wasn't listed on other laptop's "my computer"(Second Screen shot below)
    Finally: : when I clicked "right-click" on "Nasreen-PC" and then clicking on "detecting and troublshooting issues", I found that windows informed me that :
    But which driver should I reinstall because I have already installed the Dell
    Wireless 1702 WiFi + Bluetooth Driver almost twice?
    A man should convert his anger and sadness into strength to continue living in this life.

    Certain driver packages contain drivers from some of the essential services only and for additional services, separate drivers must be installed. Additionally, the service is installed only if a compatible device is installed (or paired).
    Therefore, you are seeing the error.
    If you are using the Bluetooth L2CAP Interface and Bluetooth Remote Control services and not able to install the services, you can try unpairing the device, restart the PC, pair the device and then check. If that too fails, you need to install a suitable
    driver, sometimes even other OEM drivers solve the issue. You can Bing/Google about this. You can also contact Dell Support for more information.
    Balaji Kundalam
    Thanks a lot,
    I really didn't understand what you mean with in your first part the service is installed only if a compatible device is installed (or paired).
    The Bluetooth is integrated with
    the laptop, then  where other services will come from, all service are related to Bluetooth.
    If there are some additional services not related to Bluetooth,
    then how can I either let them functioning well or disable them in order to get rid of the yellow exclamation mark
    on the name of my laptop in the Device and printers.
    Also, I really have installed a
    BCBT7(Broadcom Bluetooth) for HP which really defined the same Bluetooth issue,
    Device manager after installing the entire setup of driver BCBT7(Broadcom Bluetooth) on HP laptop
    but  when trying to install the same
     BCBT7(Broadcom Bluetooth)  on Dell,  I faced the error below, although there is an icon for Bluetooth in
    the system tray. Also, the Bluetooth is integrated as
    you have seen in the device manager. 
    You didn't answer me: Third:: I noticed that the name of Laptop whose Bluetooth was added listed in 'My computer' for the laptop whose
    Bluetooth is having some problems in the device manager.(First Screen shot below)  However, the name of the laptop whose Bluetooth is having problems wasn't listed on other laptop's "my computer"(Second Screen shot below)
    A man should convert his anger and sadness into strength to continue living in this life.
