No audio device

Posted on 2011-10-06
Last Modified: 2013-11-08
I am trying to play sounds on one of my user's computer but of course something is happening again.

so here is what I tried and the result.
I updated windows with the latest updates, uninstall and reinstall the driver for hte sound card, uninstall the hardware from the hardware tab of system windows and try to redetect it, still nothing.

I have 2 machines exactly the same(optiplex 745) so I took the hardrive from the other machine( the one that works) and put it in the computer that I have an issue, the audio worked fine.I was able to  play sound. If I take my hardrive and put it in the good computer ,then it doesn't work , I can't play sounds. so it's something on the harddrive and not a hardware issue.

so when I go to the sound icon in control panel I see "no audio device" and I don't have the volume mixer at the bottom right of my screen.

I think it's either a driver or a file that got corrupted or a registry issue, but I can't figure out how to fix that .
Any help on getting this matter resolved would be greatly appreciated.
it's a windows XP pro by the way. and the sound card is integrated into the mother board.

    My advice would be to find the service tag and try to locate the correct driver. I have seen Dell ship the same model, but have different hardware or audio codecs. I'm not saying it happens often, but just that it does.

    I would then try uninstalling the audio driver, then reboot, reinstall and see if it works at that point.

    Give this a try if you would and we can continue troubleshooting. Sorry about your trouble, but I'll do what I can to help.

    Try the Windows automatic driver installation procedure.  It may be able to find the audio driver automatically.

    Start, Settings, Control Panel, System, Hardware, Device Manager.  In the list of device there will be at least one Unknown Device, or possibly Audio Device, with a yellow or red check mark.  Right-click on the device and select Update Driver.  When the hardware update wizard appears, confirm that your system has Internet connectivity, and select "Yes, this time only."  If Windows Update knows which driver you need, it will download and install it for you automatically.  Otherwise, as bwiser1 says above, you'll need to install the driver manually.

    I already tried the uninstall and reinstall from the DEll with the service tag and no luck and I also tried to uninstall from the device manager and readd it but no luck as well.and as you can see I don't have the yellow check mark next to any devices.

    On the Sounds and Audio Devices properties window, click the Audio tab and see if you can assign the SoundMAX device to be the default device.

    since it worked before, a system restore to that date can help you out quickly
    also - is your sound card installed in device manager, without error showing ?
    and is the sound enabled in the bios?

    here the complete checklist :
    -check if the device is enabled in the bios
    -in device manager, check if the card is installed without errors
    -look if there are driver updates available, and install them
    -if needed, install / uninstall the  UAA HD Audio Bus driver
    -start>run>services.msc  and check if the Windows Audio service started and set to automatic?
            then, from Device Manager>view   click "show hidden devices" , now  right click your sound devices, and select Uninstall.
            Reboot, and cancel the wizard to reinstall
            Install your latest drivers, and reboot to complete the install......
    -in the audio and sound applet>audio tab check if the sound card is selected
    -in the volume section, check if the sound is turned up enough, and NOT muted
    -in the audio and sound applet>sounds tab select the start windows sound, and check if you can play it
    -check if the speakers are connected to the proper sound output (green)
    -test the speakers on another PC

    of course, if the sound device is bad - it won't work, but you can test that by running from the live Knoppix cd - you should hear the welcome sound :
