Hi i have compaq 6720s after re install of window xp my sound is not working I m gating msg no sound device pls help me


If you have not run Windows Update, this is the place to start. Go to Start - Programs - Windows Update at the top of the menu. It will detect any updates required or optional for your PC. It will also check for any hardware updates that are available for your system. You should select to install of the hardware updates and see if there is an update listed for your sound card. It will be obvious if there is one. If not, let me know and we will go get this from a different angle.

    My audio on my pc is not working says no audio output device found i have a hp paVILION A6177C DESKTOP RUNNING WINDOWS VISTA


    The problem here why there's no audio device detected on your system , the software or driver for the audio device is not installed on your computer system, so that's what we're going to do.
    I will provide you here a link for the direct download of the audio device of your computer, so just download the audio driver and then once done you need to install the software. This is a executable file so once done downloading run the software to automatically install it to your computer and finally restart the computer to complete the installation.

    Here is the link for the audio software that you need.

    My realtek audio driver is not getting installed. everytime i am trying...at the end its showing a message install failure. pls help..


    Hi,

    1. Make sure your installation windows XP has been updated to service pack 1 or service pack 2 before continuing. Right-click on “My computer” icon on desktop. Select “Properties\ General. If your system does not include service pack, please update from Microsoft's official website. Connect to internet and launch “Internet Explorer”, click “Tools” on the tool bar and select “Windows Update”.

    2. Make sure that the “Microsoft UAA Bus Driver for High Definition Audio” exists in “Device manager\ System devices”. Right-click the “My computer” icon on your desktop. Select “Properties\ Hardware\ Device Manager. If the “UAA Bus Driver” does not exist, install it from the download link below to install on your system (for some reason, Microsoft does not post a download link for this update anywhere on their site). Launch the sp32646 file you have downloaded from HP's website (URL below) and reboot computer after the installation.

    3. If the “Microsoft UAA Bus Driver for High Definition Audio” is working properly, there may be an “Audio Device on High Definition Audio Bus” or "Realtek High Definition Audio" behind “Sound, video and game controllers” or an “Unknown device” behind “Other devices”. Please disable any of these devices. You can skip this step if device mentioned earlier does not exist in “Device Manager”.

    4. Disable the “Microsoft UAA Bus Driver for High Definition Audio” under "System Devices".

    5. After that, uninstall the “Microsoft UAA Bus Driver for High Definition Audio" by right-clicking the device and select uninstall.

    6. When finish with the above steps, click the “Scan for hardware changes” button by clicking on the computer icon with magnifying glass toward the top of the page. When the “Found new hardware wizard” is displayed, don't click the “Next” button. Instead, cancel the installation by clicking cancel.

    7. You can now install the audio driver from the driver file that you have downloaded from the internet or from your driver CD/ DVD.

    Thanks.
