Hi again "robinb":
You can open up the pc and normally find the model number and maker of
the board or easier, most pc manufacturers have a lot of information about
the technical specifications for your pc somewhere in their support section.
Your board may contain Intel components on a board manufactured by a third
party for your pc maker so it won't be easy to find am exact match to an
Intel manufactured board. I would look for the board chipset model # and
audio chipset version that's listed for your pc and try to find an Intel
board with the same. Or you can just take a chance and pick out an
IDT(formerly SigmaTel) driver for an Intel board with SigmaTel HD audio and
try to install it.........if it doesn't work the installer should tell you it
won't work. If you install it successfully and have probs you can roll back
to the previous driver in Device Manager. Or best of all, you can wait 'til
Microsoft updates your driver in Windows Update, or install a pci audio card
as mentioned in other posts. Since I build my own PC's and have several,
I'm more prone to experimenting even if it means having to re-store or
re-install the O.S. which is not something a lot of people want to mess with.
