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.
Windows 2000
1. Open the Control panel
2. Open the "Sounds and Multimedia" icon.
3. Verify the "Show volume control on 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.
Windows 95 / 98 / ME
1. Open the Control panel
2. Open the "Multimedia" icon.
3. Check the checkbox for "Show volume control on the taskbar". If this section is grayed out, attempt to change the Playback "Preferred device" by clicking the down arrow and changing to an alternate selection. If that is also 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.
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.
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.
Defective hardware
Finally, if all of the above recommendations do not resolve your issue it is likely that either the sound card is physically bad or that the operating system is severely corrupt. We recommend you contact the Windows Operating System Support.
