Troubleshooting Sigmatel Drivers
What happens if Windows 7 doesn't find your Sigmatel drivers?
It depends on which company manufactured your computer. Most Sigmatel drivers will be for computers that are manufactured by Dell computers. In the early weeks and months when Windows 7 was in beta and even into the official release, some of the Dell drivers for the system were not yet ready to be used. The way around this was to use similar drivers from other computer systems and other operating systems.
For example, the Sigmatel Driver for HD Audio may not be found for your system under Windows 7, or it may not work on your system. The solution for this to find the same driver for Windows Vista or Windows XP. This seems to be a workaround for many Dell systems, which allows drivers to work when they otherwise would not.
If you just purchased your computer, the drivers for your system may be on one of the discs that came with it. Again, depending on the computer manufacturer, this may be a separate disc labeled 'system drivers' or may be a part of a restore disc.
You can also try to find and install your drivers manually. Download.com has good listings for different drivers for systems. The best part is the user comments, in which normal users will tell you if the driver worked or not.
In the case that Windows 7 does find the Sigmatel driver, but you are still not getting sound -
- Check the device manager to see if there is a question mark or exclamation mark next to it. You may need to update your drivers
- If the device shows up with no marks in device manager, check to make sure your speakers are on and that you do not have the volume on your computer muted. Also check to make sure that the computer speakers are plugged in correctly on your computer.
Windows 7 makes it much easier to find drivers, though sometimes driver can be hard to search for. When in doubt, use the tools that are built into the operating system.
