For users comfortable with reinstalling their audio driver, if that is the only reason that WU is not offering SP1, it should be fine to install from the download center.Īs Anthony said, we're continuing to work with all the vendors listed in the KB article to get updated drivers posted on Windows Update.
SIGMATEL AUDIO CODEC FOR VISTA UPDATE
For average users, once the driver is on Windows Update then the SP1 install will work fine. The older versions work on SP1 when installed with the Sigmatel/IDT installer, they just don't reinstall properly as part of the SP install (sometimes, not always). The new versions handle the migration during the SP install properly. Most of the Sigmatel Audio driver issues with SP1 is simply that the driver may not work properly after an update from RTM and needs to be reisntalled. Please reply to this post if you have any questions. Those who do not receive these updated drivers on Windows Update and remain blocked from installing Windows Vista SP1 need not to worry – we continue to work with OEMs in providing updated IDT/SigmaTel drivers to Windows Update. Those who receive these updated drivers will no longer be blocked by Windows Update from seeing and installing Windows Vista SP1. If the driver does not have that fix, Windows Update will not offer Windows Vista SP1 to you.Īt the end of this week, Windows Update will begin providing updated drivers for some OEM PCs running IDT/SigmaTel drivers. If no *.cat files exist we look at specific versions (mainly on OEM PCs such as Dell, HP, and Sony) that have the fix that was made prior to 12/17/07. If the Sthda*.cat or Stwrt*.cat files exist on your PC AND have a modified date of 12/17/07 – the Windows Vista SP1 block filter is not applied and Windows Vista SP1 should be offered to you via Windows Update.
Last week we updated KB948343 to reflect some changes we’ve made to the IDT/SigmaTel filters that block Windows Vista SP1 from being available to folks running some versions of IDT/SigmaTel drivers we’ve flagged as problematic:
