    Hi chap, please try a BIOS upgrade first, if that fails to work.. I would advise that you try and upgrade to SP2, as sometimes certain PCs do experience hardware detection problems when a service pack lower than they expect is loaded. What kind of computer is it?

    From dxdiag, it looks like your sound card hardware is detected. However, your computer sound is running with the generic Windows driver. You should install the hardware specific driver for your machine. Do you know make/model of your computer or motherboard? The support site from the vendor should provide the hardware specific drivers for you machine.

    Let us know if you need further help (fyi.. in the snippet from dxdiag below, note a driver is listed for your sound card but the Driver Provider is Microsoft! That means it's running the generic sound driver)
