Verify the following:
•        Check the Microsoft Volume Control or the Audio Mixer Program mute options and
volume sliders.
•        Ensure the speakers are properly connected to the audio card’s output connector.
•        Check the volume control and power connection of the speakers, if they are amplified.
(Refer to the speakers documentation for detailed information).
•        Ensure a hardware conflict does not exist between your audio card and another device in
your system.
•        PCI bus mastering devices may be interfering with the operation of the audio card.
Temporarily remove non-essential PCI bus mastering devices. If the device is a display card,
upgrade the display card drivers, or set the card to the default Windows VGA mode
