What to do about your Missing SigmaTel Driver

SigmaTel began as a Texas-based electronics company voted Best Place to Work in Austin in 2006. Between 2002 and 2006, SigmaTel’s audio soundcard technology placed it at the top of the heap when it came to audio quality. The first generation of the iPod shuffle, Dell laptops, and multiple Dell desktops utilized SigmaTel products, as did the Sony Vaio notebook and others. One hundred and fifty or so portable mp3 media players also used SigmaTel's revolutionary System on a Chip (SOC) technology in their products. The SOC was a perfect fit for mini-devices because there's no need for a place to store external RAM and all its necessary accouterments, making the SOC a natural for pocket-sized audio sound.

Over 100 million audio devices using SigmaTel's System on a Chip (SOC) were sold. But when the upgraded iPod shuffle came along, SigmaTel products weren't included. While SigmaTel chips were installed in over 70% of all mp3 players, SigmaTel also provided SOC software to manufacturers of electronic equipment to drive current and emerging audio and video applications.

The company eventually won Samsung televisions to its list of customers. SigmaTel technologies are used in Samsung's SGTV5800 Audio Solution as well as the SGTV5900 series. In 2006, SigmaTel was acquired by Integrated DeviceTechnology Inc. (IDT), and then later purchased by Freescale Semiconductor.

The SigmaTel brand has had its share of problems when it comes to the audio drivers it has produced, mainly for motherboard-based PC sound solutions. In the spring of 2008, Microsoft put out an IDT audio driver through Windows Update, but the IDT driver didn't work. It had the nasty tendency to wipe out the audio system completely after download. Dell owners using computers installed with the new SigmaTel audio drivers were storming the technical message boards with complaints of inadequate or missing audio drivers.

By mid-May 2008, Dell released a new SigmaTel driver package, the R182475, identified as a solution for Dell's OptiPlex 740 models. Dell, unfortunately, was not correlating its SigmaTel driver file to the PC models that were using the chip, resulting in confusion as to which driver to install for which PC. Some of the recommended drivers are not linked to the proper PC model applications, so it's important to do some checking to select the proper driver. With the convenience of building PCs to personal specifications, there's often changes made to the base operating systems of a particular model, so model alone just doesn't provide enough information to select the proper driver.

To determine the update for a particular PC, identify the exact PC model by looking at the advanced systems detail report available on the PC itself. Using this model number as the guideline, then it is possible to select the driver update which is necessary for that particular system, alleviating the frustration of poor audio quality, or of wiping out the audio altogether.

Early 2009 saw the layoff of 70% of the SigmaTel crew, following a determination that SigmaTel products would no longer be developed. All that's left of the company is a few techs to support OEM customers should they need assistance, until the life of their products is spent.
