hope this helps you

You need to find the web site of the motherboard manufacture and download the audio device drivers for your motherboard. If you have the CD that came with the motherboard you will find them there.

Good luck

if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer

1) Check all of the drivers in the device manager (I'm using on deck sound). All are functioning properly.
2) Do the suggested "Add Hardware" option to update to the latest drivers, all of which I already had.
3) Start -> Run -> services.msc -> Windows Audio, and made sure it was started up and set to automatically start on setup.
4) Made sure that the sound was enabled in the BIOS.
5) Insert a modified "machine.inf" file into the Plug and Play Enumerator.
6) Start -> Run -> msconfig -> Services, and made sure Windows Audio was checked and running.
7) System Restore (to check if one of the updates might have caused the problem)
8) Make sure the speakers were still functioning properly

is your hardware enabled ?
check it out via control panel -sound,speech and audio - sound and audio devices - hardware.
highlight your sound device and click on properties.
at the bottom of the window check that the device is Enabled.

Do you see the sound plugs on back of your pc? If you have those on back of your pc near the keyboard, mouse or video plugs, then you have onboard sound & it should be enabled in your pc's Setup. Look in Device Manager (right click My Computer, select Properties, then hardware) to see if the audio hardware is listed. If so, does it show it's working properly or needs a driver? If it's there and shows to be working properly, look in the Control Panel for the Sounds icon & see if it's been disabled. Make sure your speakers are plugged in the correct plug & are good.
If you see the audio plugs in back of your pc
& no audio device is listed in Device Manager, the audio might be disabled in your
machine's Bios Setup. If it is, then enable it.
Windows should install it then next time it
starts.

First check whether the audio volume is not muted, and turn the volume all the way up, if you didn't already try that.

Did you try playing the system sounds? Enable them from the Control Panel (double click the sound and audio devices icon from the Control Panel), if you didn't try them, or if they aren't enabled. Then, play one of the system sounds from the "Sounds and Audio Devices" (second tab, labeled sound).

Can you see a speaker icon in your system tray? If yes, double click it. Do you get the 'Master Volume' control or do you get a message that says something like you don't have audio enabled?
If you get such a message, then the audio drivers are missing or corrupted, or not properly installed.


If you can open the Windows Device Manager, open it and check whether the sound drivers are present and are functioning correctly.

(For opening it in Windows 7, open the Control Panel from the Start Menu. Click on the System and Security link. In the System and Security window, click on the Device Manager link located under the System heading.  (Another easier way is to click the Start button and type the following command in the search box: devmgmt.msc Then, hit the enter key.

In Device Manager, expand the 'Sound, video and game controllers' (click the plus sign next to it). See that the sound driver is listed. Double click the item in that list that contains the word "audio device" in its name. Does Device Manager say that the device is working properly?


Instead of manually searching for the drivers, or your old drivers CD (you probably don't even remember where you kept it), you can download this driver scanning tool from here: http://xpdrivers.com/index.cfm or directly from this link: http://xpdrivers.com/download/download.cfm

After you download it, double-click it to install it and follow the simple instructions and run this tool to scan your system. It will inform you and update the needed sound drivers.

Hope that helps,

Some FAQ about laptop sound and Windows 7: http://windows.microsoft.com/en-US/windows7/Sound-cards-frequently-asked-questions

Onboard audio is disabled in the BIOS
The BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. Go to the Advanced > Peripheral Configuration menu to make sure onboard audio is enabled.
Audio settings in the sound mixer are incorrect
Check your audio mixer software to ensure audio is not muted or the volume level is not turned too low.
The speakers or headphones may be connected to the wrong jacks
Make sure you connect all speakers to the correct jacks. If you connect them to line-in or microphone jacks, they won't work.
Audio drivers are not properly installed
Check Device Manager under the Sound, video and game controllers section for any errors associated with the audio driver. Reinstall the audio driver if necessary.
Audio to back panel is muted if front panel is connected
Check your audio mixer software for a setting that mutes back panel audio if you have plugged headphones into a front panel audio solution. Uncheck this setting to allow audio to both the back and front.
Sound Playback is set to wrong device
In Control Panel > Sounds and Audio Devices, go to the Audio tab. Check the default device for sound playback; there may be multiple selections. Select the desired device, either rear panel or front panel.

Probably a driver problem. Go to device manager and then sound devices and update your sound drivers...Or it could be a problem if the sound card is intergrated. You ca purchsed a pci sound card and fix it. You might want to check the bios and make sure your sound is enabled,,Hope this helps,,,,Darren

Verify that the audio card is in the Device Manager list and has NO conflicts. If it is in the list with NO conflicts, verify that the cord from the speakers is in the correct output on the audio card (typically GREEN output). If you DO NOT see the audio card in the Device Manager list or it has some type of symbol ( ? or ! ) next to it, try restarting the PC and enter the SETUP menu (or BIOS). Go to integrated peripherals and check to see if the on-board audio is enabled/disabled (if you have a motherboard with on-board audio, and no other audio expansion cards in the system, this option should be enabled, and just the opposite if there is an expansion audio card). Save and exit, let system boot up. You should now be able to see the device in the Device Manager. Next open SOUNDS AND AUDIO DEVICES in the CONTROL PANEL, and verify that there is a bound sound device to the system. Reinstall drivers and restart (if you bought this PC from a manufacturer, there should be a disc with these drivers on it) . If none of this works, you may need a new audio card.

ATI is the graphics card developer. Your motherboard has onboard audio that appears to be Realtek. You should not have an ATI sound driver... as they don't exist.

I'm assuming you're using WinXP to make thing simple. If you're using Vista, try to do the equivalent.

Since your graphics card is capable of HDMI, the problem could be that the card expects to output audio through your graphics card rather than the sound card. Check start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings -- go to the Audio tab and make sure it says Realtek for output. If it shows more than one output device, set it to realtek. If it doesn't show realtek, follow the below instructions, and then double check at the end that the Output device is set to Realtek.

1>Please go to HP's site and download their Audio drivers.
2>Go to Device manager -> Sound, Video, and game controllers.
2.1> Does it have an entry saying "Realtek blah blah Audio" there? If not, what entries does it have for audio? Ignore Audio Codecs and Legacy Audio Drivers.
2.2>If there's nothing there, you need to install the drivers you downloaded. If there is something there, please continue to #3.
2.3>After installing the driver, restart computer.
2.4>Once computer is restarted, go start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings. Hit the button labeled Advanced and adjust the speaker setup to whatever you have - surround sound, 5.1, quad, stereo, whatever.
2.5> Go to #5
3> If there is anything that says Realtek/Azalia Audi, right click it and Uninstall.
3.1> Restart computer.
4>Install audio driver you downloaded, and perform #2.4.
5>Find the driver icon (there's probably on in the task tray) or find it under start -> Control Panel -> Sounds and audio. Set your speaker settings there as well. Audio I/O should specify what ports go to what speakers What you set in windows should match the Realtek audio manager's speaker setup.

If problem persists, please report this.
