First go to the Intel web site and download the latest sigmatel Vista
drivers. There is one that is quite recent. I looked under motherboards and
found one that matched mine as closely as possible as far as chip set, etc.
The driver that comes up will work with many motherboards, so it isn't that
MB specific. Also download (if you don't have them already), the latest
WinXP driver/program for your sigmatel chip. In Vista, uninstall any
sigmatel drivers you already have (under Add/Remove programs.) Next go to
the folder where the WinXP driver (upzipped) is located and right click on
the setup file and choose compatability mode/ WinXP. Install those drivers
and reboot. You should have some kind of wierd sound that is barely
recognizable, and you should have no flag under the sigmatel sound codec in
device manager, as well as your sound icon should show an installed sound
device. Now unzip the Vista driver you downloaded. Go to device manager and
select the sigmatel codec. Select upgrade driver and then say you will
browse for the folder. Browse to wherever you downloaded the Vista driver
and go to the WDM subfolder. Choose this and let the program install the new
driver. When you reboot you should have decent sound, music, etc., and when
you select properties on the sound icon, it should show the sound device,
with the speakers and mike working. Good luck! Hopefully Intel will
eventually have a Vista driver that will install the sound device as well as
the driver and you won't have to go through these hoops to get it installed.
