Bad timing...4th quarter of the super bowl.
Right click on My Computer and choose "Properties". Click the "Hardware" tab, then the "Device Manager" button. Expand (click +) Sound, video, and game controllers. Locate your sound device, right click on it, and choose "Uninstall"...accept the change.
Reboot and let Windows install the device. Try the sound and let me know if there is any change.

From Control Panel, "Open Sound and Audio devices", and click on the "Sounds" tab. What is listed in the "Sound Scheme" field?

If not, Windows keeps a Device Manager entry for every piece of hardware that's ever been recognized by the system, regardless of whether it is currently present in the machine or was even set up correctly in the first place. The "View Hidden Devices" option in Device Manager won't show you these "residual" drivers.
You can force it to show you everything by going to My Computer, Properties, the Advanced tab, Environment Variables, and adding a new system variable with the name "DEVMGR_SHOW_NONPRESENT_DEVICES" and a value of 1. Now opening Device Manager and choosing "Show Hidden Devices" really will show you everything.
Another alternative is to issue the following from a command prompt.
Leave the command prompt window open while you look in Device Manager. Close it when done. This is temporary and goes away when you close the command prompt window so the Environment Variable method is better.

Give me a bit to research and I'll post back with what I find.

What do you see if you select it and then click on the Properties button? Can you then click on the Driver tab and rollback the driver?
