Built-in microphone not detected in Windows 7

Hi all!

I'm having this problem since I installed Windows 7 on my Acer Aspire 5715z. Right after the installation of the internal microphone has stopped working. First I thought it would be a driver problem, but did not find the specific driver for windows 7 on the ACER Web page.
I did fi the issue for a while now, but yesterday I re - install Windows 7 and the problem was still there.
I decided today to find an answer to it. I saw that many users Acer have suffered.
I went through the Panel--> sound--> recording--> see off / disconnected devices it does not work.
I ran the windows troubleshooting and nothing happened.
I went to the Device Manager and in his checked for changes on the hardware. The only item listed here is "high definition audio device" which according to me is not the microphone internal (I think this is supposed to be realtek?). In any case, I uninstall and reinstall and search for the latest drivers.
I ran the microsoft fixit, but nothing is happening.
I'm out of ideas. Any help would be most appreciated.
Thank you very much

I could solve it by downloading and reinstalling the realtek drivers

Thank you very much!
see you soon

  • XPS13 built in microphone not detected.

    On a Dell XPS 13 Ultrabook, running Windows 7 ultimate (downgraded from Windows 8).

    The system is not just see the microphones.  On the windows volume control options/recording devices, nothing comes up.  Even on Dell Audio / microphone and Skype microphone.  Can any ideas on how I fix? I tried to download all the drivers on the DELL site using detection of automatic service tag and system DELL detect to find missing drivers, but some chipset drivers listed lead to a blank page without downloading anything.

    Go back to the recording of the sound Properties tab (right click the audio icon, and select recording devices), and then click the blank white box, right-click and select devices see off, then do it again and select this option to show disconnected devices.

    If the microphone shows always then go to the Read tab and see if the word 'Realtek' is under speakers. If this isn't the case, then the Realtek driver is not installed.

    If the driver is there and is still no microphone so it could be faulty. The microphone was working at all with Win 8?

    IM on Windows Vista Home Premium.
    I had this problem before and I managed to fix it by unplugging and reconnecting the Cd/dvd drive (nothing to lose, no more warranty), but after doing a system restore, the problem resurfaced again.

    The hard drive is a Toshiba MK1637GSX ATA Device
    I tried to use the pages of Microsoft support without success. I have no upper and lower filter.
    I already tried with also Device Manager nothing doesn't.

    Help, please!

    Hello

    Please start from the top and do it, even if you've done it before as is often the
    all operations which solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
    Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
    This will refresh the default driver stack.

    Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
    slight corrosion on the contacts (usually for a laptop) and other issues.

  • HP v125w 2 GB drive flash not detected by windows

    My flash drive is not detected by windows what should I do

    I have a HP v125w 4 GB flash drive that works on Windows 2000 and 7.  However, I also have a disk 16 GB flash of v125w HP which works on Windows 7, but was not recognized by my system Windows 2000.  Here's what I did to get Windows 2000 to recognize (this may not work for everyone, but it did for me).

    I plugged the flash drive to 16 GB on a Windows 2000-based USB port and ran:

    Norton SystemWorks-> Norton Utilities-> find and correct problems->

    Norton Disk Doctor-> diagnosis

    that gave me the message:

    Insert the diskette to diagnose in the E: drive.

    So, I ejected the flash player, it plugged into the USB port and you click on diagnose again.

    Norton Disk Doctor consulted the flash drive, diagnosed and gave the following report:

    There is no problem detected on drive E:
    Partition table... Jump
    Structures of files... Ok
    Surface test... Jump

    After this, the flash player was working fine on my Windows 2000 and Windows 7 computers.

    Thus, this procedure is awakened somehow the reader as much as to be recognizable by Windows 2000.  I hope this helps you.

  • Brother printer has not detected by Windows 7 64 bit.

    Brother DCP145C has not detected by Windows 7 64 bit. What port is recommended for the local printer - LPT1? Windows 7 should detect when the USB connection, but there is no activity. Similarly, the mode to scan on the printer is not responding to "check connection". Thank you.
    Checked the port LPT1 and COM on Device Manager and seem to work correctly. No updated driver needed updated port.

    Hello Richard,.

    If several USB devices are plug-and-play, printers need a print driver to work even on a USB port. I went to the Brother website and a research on the model of printer "DCP145C" increase any responses - are you sure the model number of the printer (not the part number)?

    You have a printer disk supplied with your printer? If you do, try to use that to install the print driver. As far as LPT1 goes, is for a printer with a parallel port (printer), and the COM ports are for those who use the ports series.

    Thus starts with the right model number and look for brother.com right print driver (or use the disc that came with the printer). Try and see if that solves the problem for you.

    Let me know how you fare.

    Kind regards

  • Yoga 12 (Win 10): Built-in Microphone "not connected".

    Hello world

    I bought my ThinkPad Yoga 12 just a month ago, upgrades to Windows 10 after a few days. Everything worked well, including speakers and a microphone. Skype has worked well.

    Yesterday, I tried to use Skype but my microphone does not work. I found that no microphone even was to be found in the settings.

    Naturally, I reinstalled the audio driver. Now, there is at least one symbol "Built-in Microphone", but is not connected. Cannot be connected. Troubleshooting tells connect me and external microphone.

    I did both disabled and disconnected devices visible in the menu.

    Anyone knows what is the problem with my microphone and has an idea how to solve this problem?
