Before you install any of these updated IDT/Sigmatel Audio drivers, check if
your "Hardware ID" number of your IDT/Sigmatel HD Audio device is listed in
the STWRT.INF and STWRT.INI files. You can obtain the HWID information of
the IDT/Sigmatel audio hardware by opening the Device Manager window (Click
on "Device Manager" from Vista's "System" control panel app under Tasks),
expand the "Sound, video and game controllers" section, double-click on
"Sigmatel High Definition Audio Codec" or "IDT High Definition Audio Codec"
to view its Properties, click on the Details tab and change the Property that
says "Device description" to "Hardware IDs". then check if the "hardware id"
is listed in the newer STWRT.INF and STWRT.INI files to ensure the
IDT/Sigmatel driver files get updated with no loss of audio in Vista SP1.

examples of certain IDT/Sigmatel HD Audio hardware ID numbers:
hdaudio\func_01&ven_8384&dev_7680&subsys_107b6051
hdaudio\func_01&ven_8384&dev_7618&subsys_80863003

And Microsoft has made changes to the Windows Update "blockers" for Sigmatel
audio drivers mentioned here:
