This problem might happen if the sound card is disabled in device manager or the drivers are not installed correctly. Check to make sure that the Sound Card is enabled under Sound, video and game controllers in Device Manager. If the issue is still not resolved try updating the Audio drivers. If you need help with the correct audio drivers for the sound card, please provide me the Device Instance ID of the sound card. To get the Device instance ID of the Sound card, right click the Computer/My Computer icon on the Desktop, select Manage, select Device Manager under Computer Management from the left pane, then expand Sound, video and game controllers from right pane. Right click the Device listed under Sound, video and game controllers, click properties, go to the Details tab, and then select Device Instance Id from the dropdown list. Make a note of this Device Instance ID.
Please do write back to us.
