SIGMATEL STAC 92XX C-Major HD Audio Drivers on Windows 7
LAB Computer Long Island have been upgrading a few of our PCs and Laptops with Windows 7 this evening and hit upon a problem with the SIGMATEL STAC 92XX C-Major HD Audio device that came with my Dell XPS M1330, Inspiron 1525 laptop. A quick google confirmed we are not the only one having problems.
Since we have now solved the problem we have post it here on my blog as we are sure it will be a popular search on Google in the coming months as the masses move to the new OS.
The symptom
The fix
Download the latest x32 or x64 (as appropriate for your computer) Vista driver from the Dell website and leave the EXE in a folder somewhere
Or get them direct from us, click for the 32 bit driver or for the 64 bit driver
Username: dell and Password: dell
Right click computer, and choose manage, then device manager
In the Sound, Video and Game controller group you will see a device called "Windows High Defintion" – delete this by selecting and pressing delete
Now having removed this device from your system you should run the Dell Sigmatel Driver EXE you downloaded previously
Your system will prompt for a restart upon install
When you restart you will get the reassuring sound of the Windows 7 start up tune and all will now be well !
Hope this helps someone, took me an hour today to figure it out.
