You can try a system restore point,restore system to an earlier time, if you have windows XP or equivalent.
I had this audio problem with my laptop a while ago,did a restore, and this seemed to work for me.

These yellow exclamation or question mark i think could mean you could have a software , hardware or virus problem, i have a virus problem some where on main computer mother board which i cant get rid of.
Try a virus scan.
hoping this helps

What is the base system device on my Dell laptop?


A base system device is any hardware device pre-installed on your laptop, such as a CD-rom drive, a USB port, an Ethernet port, video card, etc. These devices all require pre-installed drivers that were supplied by Dell with the factory setup. The most common problem is to have one of these driver files corrupted or deleted by accident. To solve a base system device driver problem, you have to go into Windows Device Manager (Look in Control Panel), and look for devices listed with yellow question marks or other indications that they have a missing driver. You either then go to the Dell support site for your laptop model, or the driver disk you may have gotten with your laptop, and reinstall the needed driver.

NOT ACTIVE AUDIO WINDOWS XP.....WHAT THIS IS SOLUTION ASUS P5KPL-AM SE


Click Start, click Control Panel, double-click System, click the Hardware tab, and then click Device Manager. 18abb370-ac1e-4b6b-b663-e028a75bf05b.jpg If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Double-click Sound, video and game controllers to expand that category. If a sound card is listed, you have one installed. If no sound card is listed, check the information that came with your computer to see if there's supposed to be a sound card installed. If there should be a sound card installed, you'll need to install one.If you think you have a sound card installed, but you don't see it under the Sound, video and game controllers category, expand the Other devices category and check any devices listed there.Laptops don't usually have sound cards. Instead, they have integrated sound processors, which appear in the same category in Device Manager.

If there's a yellow question mark next to the name of the sound card in Device Manager, there might be a problem.

  1. Right-click the name of the sound card, and then click Properties.

  2. Click the General tab, and then look in the Device status box to identify problems with the sound card.

  3. Although most speakers have a volume control, you can control the overall level of sound using Windows.

    1. Open Volume Control by clicking the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33.png, clicking Control Panel, clicking Hardware and Sound, and then, under Audio Devices and Sound, clicking Adjust system volume.

    2. Under Main Volume, move the slider up or down to raise or lower the volume.

When i on the lapto, and login on yahoo it shows me usb not recognise


When a USB device is not recognized, Yahoo is hardly to blame. To diagnose a faulty USB device, first:

On Windows 2000/XP:
  1. Click Start, click Control Panel, click Performance and Maintenance, and then click System.
  2. On the Hardware tab, click Device Manager. Double-click the type of device you want to change.
Windows Vista/7:

  1. Click on Start and then Control Panel.
  2. Click on the System and Maintenance link.
    Note: If you're viewing the Classic View of Control Panel, you won't see this link. Simply double-click on the Device Manager icon and then proceed to Step 4.
  3. In the System and Maintenance window, click on the Device Manager link near the bottom of the window.
  4. You can now use Device Manager for whatever you needed it for - updating device drivers, viewing the system resources that a particular piece of hardware is using, etc.

Look for devices with exclamation points, usually in yellow.

Name any of those devices here.

My video stopped working on my Logitech QuickCam Pro 9000. No picture or video. I just used it last on Tuesday and now nothing. I even reinstalled the software..still nothing. Help!


Check if the device enumerated
click on Start
Computer > right click > manage > Device Manager, click on it

You should see in "Imaging devices" a "USB Video Device".

If not then device did not enumerate.
If you see a yellow circle in "oher devices" try to updated the driver by clicking on it.

I don't know what kind of cam I have?


1. Connect your web cam
  • Attach all power cords (e.g. laptop and/or web cam).
  • Plug your USB cam directly into your computer (do not use any external USB hubs). Turn your cam on
  • As long as your web cam and computer hardware are working, Windows should detect it!
2. Open Device Manager
  • For Vista
    => Click Control Panel. If you have Control Panel Classic View, click Device Manager
    => Click Control Panel. If you have Control Panel Home View, click System and Maintenance->Device Manager
  • For XP
    => Click Control Panel->System, then Hardware tab, then Device Manager button
3. Find your web cam in Device Manager
  • Understanding Device Names
    => Windows provides user-friendly device names to accomodate us humans. As far as Windows is concerned, the device name is simply a comment!
    => It's those cryptic Device Identification strings that really identify a device
    => Device Manager displays whatever device name it happens to find in the device driver
    ...==> If Windows finds NO device driver, your web cam may be named “Unknown” or "Other" device
    ...==> If Windows finds the WRONG device driver you may see your web cam with the WRONG device name
  • How to find your web cam
    => While your web cam is connected, look through all of Device Manager for devices with a yellow icon (probably a yellow question mark)
    => Look if a device category Other Devices. Also, be certain to expand the USB category to check all devices listed under it
    => Your web cam will appear as a device with a yellow icon (probably a question mark)
    => Click on thumbnail to see the full sized image
    How to verify the device you found is your web cam
    => Your web cam device will only appear in Device Manager when the web cam is powered on and connected
    => Disconnect your web cam. Verify the device you had found is no longer displayed in Device Manager
4. Find your web cam's Hardware Ids
  • In Device Manager, select your web cam device, rt click Properties. Click Details tab
  • Select Hardware Ids from the pull-down. You'll see a list of one or more Hardware Id strings

Audio


Hi, Confirm that there is an audio device installed in your PC > right click on My Computer, Properties, Hardware tab, Device Manager button, expand Sound, video and game controllers, It's got to be there, with no yellow or red marks. Also in Start, Control Panel, Sounds and Audio Devices, Audio tab, you should have something in Default device. If none likewise in Device Manager or a yellow or red mark, you have to re-install your drivers by right clicking on the mark and click Update drivers. If they're there with no marks, ensure that they are enabled. Perhaps further assistance maybe made available if you can post brand/model of your PC and/or motherboard. Good luck and kind regards.
