That error means there is a problem with your sound card or its driver. To fix the problem, check if the driver is already installed. If the driver is already installed, try to uninstall and reinstall the sound card driver. Download the free version of Revo Uninstaller and install it. Once installed, start Revo then select your sound card software among the applications and click “Uninstall”.

Follow the normal uninstall process. When you are prompted to restart the computer, click to restart later. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, exit Revo then restart the computer. After booting, install the sound card driver back.

On the other hand, if you haven’t installed the driver yet, you need to install it first to be able to play music on your computer. Download the latest sound card driver from the following if your machine is from these manufacturers:

• ASUS Download Center
• Intel Drivers & Software
• Acer Drivers and Manuals
• Toshiba Support
• Lenovo Technical Support
• Dell Drivers & Downloads
