No sound driver found

Open Control Panel, Device Manager, Sounds, Is the audio device listed? Enabled? The Windows XP drivers can be found here, install and reboot: http://support.gateway.com/us/en/emac/product/default.aspx?modelId=1645

Does the icon come up in the tray if so check
to see if it is not muted

Go into device manager/propersties and see if
it lists any problem,if it says everything is working
properly remove it and let it check for changes in
device manger when it reisstalls see if that works

there is no longer any support for XP.

Look at the driver properties. I suspect a generic Microsoft driver has been installed and that driver doesn't work correctly. (Right click on the audio device from Device Manager and select Properties. Then check the Drivers tab. Look for the line with Driver Provider.)

I can't find a MX6400 listed on Gateway's driver site, http://www.gateway.com/gw/en/US/content/drivers-downloads . There are the MX6410 and MX6420 listed. Both of these have a Conexant audio driver for XP and Vista. The Vista driver may work under Windows 7. (Make sure to correctly select the 32-bit or 64-bit depending on your OS version.) Download the driver and try to manually install it. If that doesn't work, try a Conexant audio driver from another laptop brand that is for the correct version of Windows 7. (Just Google Conexant audio driver Windows 7.)

I hope this helps. If you have a problem, please let me know what your Device manager claims the manufacturer is on the HD audio device and the driver manufacturer listed in the Properties. Also add a comment if you see any error messages when trying to install a new audio driver.

Hi,
sounds like driver related problem, download this tool: Driver Update Software for XP Vista 7 8 update your drivers, and won't be any problem.

There are 4 ways you can download and install audio drivers :

1.From Device Manager

(1).Click Start, type Device Manager in the Start Search box, and then press ENTER.
(2).In the Device Manager dialog box, expand Sound, video, and game controllers.
(3). Right-click the device, and click Scan for hardware changes.
You should see a message that a hardware device is being installed. Additionally, the uninstalled audio device is now present in Device Manager.
(4).Close the Device Manager dialog box, and then determine whether you can hear sound.

2.From the motherboard or installation CD - If your computer came with a motherboard CD, the audio drivers should be on the disk.

3. From manufacturer's website - If you don’t have the CD go to your computer manufactures web page to search for updated sound driver software. Read the instructions on the download pages carefully before installing.

4. Microsoft's Windows Update feature : If there are no updated sound drivers available, use Microsoft's Windows Update feature. Connect to the Internet and try the following items until Windows Update opens:

(1).Click Start, and then click Windows Update (if it is listed).
(2).Click Start, click Settings, and then click Windows Update (if it is listed).
(3).Click Start, click All Programs, and then click Windows Update (if it is listed).
(4).Go to Microsoft's Web site and click Windows Update from the Downloads menu.

hi reloaded windows xp on medion mim2220 laptop unable to find sound device to work sound for my laptop cant play any music can you help please

Missing or lost sound in Windows 95 / 98 / ME / 2K / XP.
Cause:This issue could be caused by any of the below possibilities.

1. Bad software settings.
2. Corrupt or missing sound drivers.
3. Compatibility issues with the operating system and/or other hardware.
4. Speaker related issues.
5. Bad or missing sound card.

Solution:Verify software volume control settings
First verify you see a small sound icon in the systray (generally at the bottom right hand corner of your screen). If this icon is missing follow the below section.
Windows XP

1. Open the Control panel
   
2. Open the "Sounds and Audio Devices" icon.
   
3. Verify the "Place volume icon in the taskbar" checkbox is checked. If this option is not available or is grayed out, skip to the next section of this document.
   
4. If you were able to check this box, click ok and close out of this window and the Control Panel.
   
5. Double-click the sound icon in the systray and verify that all the sound volumes are mid-way or higher.
   

verify the installed driver settings

1. Open the Windows Device Manager
   
2. Verify there are no conflicts or errors listed anywhere in Device Manager. If conflicts exist skip down to conflicts section.
   
3. Verify no other devices are listed. If other devices are listed skip down to other devices section.
   
4. Verify that your "Sound, video and game controllers" category is listed, if not skip down to the missing sound card section.
   
5. If no conflicts or other devices are listed and your sound card is listed with no conflicts, skip to the next section.
   

Conflicts section
If conflicts exists with your sound card and/or other devices installed in your computer it is likely that either the drivers are not properly installed for that device and/or the sound card and/or other devices are conflicting. If you open the properties of the device that is conflicting and view the properties, additional details about the conflict can be found. Additional information about error codes as well as help with Device Manager can be found on our Device Manager section.
If you are unable to locate additional information about your issue or are unable to resolve the issue, follow the below steps.

1. Under Sound, Video and game controllers highlight each device and press the delete key to remove the device.
   
2. Reboot the computer.
   
3. As the computer is booting the system will detect the sound card and any of it's devices and re-install those devices. If prompted for a location of drivers, try pointing it to your sound card CD and/or your Windows CD. If this does not work or is unable to locate the proper files, you will need to get the latest sound drivers from your sound card manufacturer.
   

Other devices section
If other devices are listed, it is possible that these other devices could be the sound card or other devices conflicting with the sound card. If any other devices are listed it is recommended you remove those devices, reboot the computer and let Windows redetect the devices.
If this does not work, attempt to determine which device is not being detected and resolve that issue first.
Missing sound card section.
If you are missing the "Sound, video and game controllers" category in Device Manager, it is likely that the sound card drivers are not installed properly, sound card has been disabled, sound card is bad, or no sound card is available in the computer. First, verify no conflicts or other devices are present in the Device Manager; if these are present it is likely they are the sound card and/or devices causing the sound card not to be detected. Second, verify that the computer has a sound card and/or that the sound card is enabled on the computer.
If this is an on-board sound card you can verify that it is enabled in BIOS setup. Additional information on entering the BIOS setup can be found on document CH000192.
If you have no adapters and/or cannot click the down arrow to select the correct adapter, close out of this Window. In Control Panel double-click the System icon / click the Device Manager tab within Device Manager and ensure there are no yellow ! or red X.
If you have either of these on any of your sound devices, attempt to remove everything under Sound Video game controllers and reboot the computer. If after rebooting the computer you still have the same conflicts, double-click on the conflicting device and refer to our Device Manager error code section giving you additional information on the error code you are experiencing.
Verify speaker connections
Verify the speakers settings and speakers are not at fault by running through speaker troubleshooting steps in document CH000034.
Sound card drivers
If you have followed the above recommendations and you are still unable to get the sound card to work, download and install the latest sound card drivers from the computer or sound card manufacturer. A listing of sound card drivers can be found on our sound card driver page.

Audio drivers for this, for Windows XP, are listed here -

http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&cc=us&dlc=en&product=366264&lang=en

Now, you stated there was no Audio device listed in the device manager. Are there and PCI Devices or Multimedia devices listed under the OTHER DEVICES section in the device manager?? Possibly with a yellow question mark listed next to them?? If so, then that may be your audio device, and the link above will send you to the correct page for XP drivers for your machine.

If there are no OTHER DEVICES listed, and nothing with a yellow question mark in the device manager, then it may be a hardware issue. Could be that the audio is turned off in the bios, or simply just bad. For which, the fix, would be just installing a PCI sound card.

Hope this helps, if not, let me know if you need further assistance.
