Start Menu/Control Panel.
Open up Administrative tools, then Computer Management.
On the left side of Computer Management, click Device Manager.
Look under Audio, video and game controllers.
Do you see any entries with a yellow exclamation mark next to them?
If you do, and it's next to your sound device, the drivers for the device are not installed.
If you don't see your device listed, next look for a category called Unknown (or something similar).
It could be listed there if the drivers are not installed.
If you don't see any yellow marks next to your sound device
Something to check:
Open Sound and Audio Devices.
Volume tab, click on Advanced in Device Volume.
Play control should open.
Click on Options/Properties. Place a checkmark by everything, click OK.
Back to Options/Advanced Controls.
If under any of the categories, you see Advanced click on that, if a box opens that has
OTHER CONTROLS/1 Digital Output Only* check if it's unchecked. (if you see Advanced in the panel Volume Control, you won't need to check any other advanced settings.)
If it's unchecked, check it.
Open up a player, add a music file, do you now have sound? If you have to, plug the speakers into every port on the card and see if it works.
*it may have another number. If it does, check or uncheck it.
