Speakers work, but the microphone does not after OS reinstalled (dv6)

Sound is played through the speakers, but the Bay internal microphone and external microphone device receive no signal. Windows recognizes these devices, but the volume on the sound Panel Monitor is inactive. In addition, the webcam works fine.

I just reinstalled the operating system and everything worked fine before this date. I installed the driver IDT High Definition CODEC (same driver as before) and the Device Manager indicates that it is up-to-date and functioning normally. I am running the same OS as soon as before reformatting (Windows 7 64-bit).

Yes, these devices are turned on and yes I have checked the noise levels of these devices.

Laptop model: HP Pavilion dv6t-6100 CTO Quad Edition Entertainment Notebook PC LM720AV

Thanks in advance!

Update: when I try to run Sound Recorder I get an error message: could not find an audio recording device.

Solved! I ran HP Support Assistant, and he recommended that I have install a BIOS update, I did. After you restart, audio input is recognized.

  • Printer HP Officejet Pro 8600 Plus works but the Scanner does not

    I recently bought a Toshiba laptop with Windows 7 Home Premium operating system.  My previous laptop is a Toshiba also upgraded to Windows 7 Home Premium operating system.  I have a printer HP Officejet Pro 8600 more all-in-one printer.  The printer/scanner works fine with my laptop more older but with the new laptop that I can't get to the printer.  I am not able to get the scanner to work.  I reloaded the software several times but the scanner still does not work.  The scanner works fine with laptop more old, even if it has the same operating system.  I get an error message that says "Scan of the computer is turned on.  You can start a scan from the printer.  Your computer is not listed as an available computer control panel of the printer.  If please restart your printer and try again. "Can anyone help with this?

    Hi ranjisamaraweera,

    Even though I'm MVP I represent Microsoft or speak. If I can and will speak
    as I think.

    The proper functioning of the printer and Scanner is the direct responsibility of the producer of material
    and no windows. There are hundreds of these devices that work correctly on Windows 7 if
    those who don't have no drivers and other interfaces which are not compatible to Windows 7 should be
    written correctly. Of course many older devices are not supported by their creators for later
    Versions of Windows. Microsoft passes but does not write drivers and interfaces
    Printers and Scanners need to function properly. So, the manufacturer and no one else, is totally
    Manager to see if there are interfaces and appropriate drivers.

    Many device makers do not write new drivers and interfaces for older hardware because either
    they cannot support the new methods or because they want to sell new hardware.

    Personally, I don't think that Microsoft is lying because they also say that device manufacturers have the
    Omos unique to provide the necessary compatible drivers and interfaces.

    I hope this helps.

    After updating my iPhone 6 (9.3.4) the WiFi signal becomes very low! I did everything, but the problem does not stop! I don't a not update my other devices & their very good WiFi signals. Please help me solve this terrible problem...

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

    (1) restart you device.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth). Channels 1, 6 or 11 are recommended for 2.4 band.

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes. Try to restore as New first and test it. If ok try to restore the backup (the backup may be corrupted).

    (9) go to the Apple store for the evaluation of the material. The Wi - Fi chip or the antenna could be faulty.

  • HP dv7-3085dx power light flashes, but the laptop does not work.

    Hello! I have a HP Pavilion dv7-3085dx. It has a hard drive Bay 2.

    Recently, I bought the caddy + cable kit and an Intel SSD. The thing is, when I plug the sata cable to the motherboard for the laptop, and the SSD to it, the laptop does not light. When I press the power button, it flashes once (the power LED flashes once), but the laptop does not light. When I press again, nothing happens.

    I tried to remove the power supply plug, battery and plug it all again, but the power light flashes once (when you press the power button) and no reaction.

    Maybe it's the sata cable: when I remove the new cable and connect the SSD with the sata cable on the 1 hard drive Bay (the cable supplied with the notebook), it works fine. The laptop starts. And when I connect the former sata cable, with the SSD on the second hard drive Bay, it also works.

    I just want to now what is the flashing light means light? Why it does not work with the new cable?

    Thanks in advance! Sorry for my bad English...

    Emilio.

    It is possible that this is a problem with the kit. I would recommend to download and install the latest BIOS update for your laptop, using the download at the following link: http://goo.gl/rbHkg

    If it still doesn't work after that, I would recommend to suppress the kit for a replacement or to try another.

  • I have a hp m175nw printer. email prints from my iphone, but the image does not work

    M175nw printer. email prints from my iphone, but the image does not work

    If the DPI (dots per inch) is less than 100, the printer will not print the photo because it would be too low in quality. Draw the image on the computer, then right-click on it and click Properties, check the horizontal and vertical dpi and see if these figures are less than 100. Have you tried to connect the iPhone to the same network as the printer and try to AirPrint peak? AirPrint road doesn't have the same requirements on IPR as the ePrint.

  • When a link to open another application and firefox is closed, Firefox opens but the link does not work

    I use Firefox on Mac OS 10.9.2, 29, this problem has occurred on the OS 10.8 ~ and various other versions of FF. I use 29 simply because I like it!

    The problem: Firefox is configured as the default browser in all directions it is possible to set as the default value. However, when I click on a URL from any application and Firefox is closed, Firefox opens opens, my last session of navigation tabs start, but the link does not open. I must return to the application and click the link again. This only happens on Firefox. I can put any other default browser and it will open the link in a closed state.

    This is happening to me, same, on Mac OS X 10.6.8 but only since I've upgraded to the latest version of Firefox, 32.0.1. I can click on a HTTP link in another application and Firefox becomes the active application, but it will not load a new tab for the link, as expected. Instead, it just sits there. I have to go back to the other application and click on the link a second time, during which point Firefox correctly open a new tab and load the destination URL.

Everything seems to be working well, but when I try to add Speed Dial, it appears to install correctly, but the icon does not appear in the menu bar. I tried several times and each time I like Speed Dial will be installed after I restarted Firefox. However, by clicking on the button will restart FF, but the icon never appears! What goes wrong, and how can I get Speed Dial to work for me, as it has always done?
