Issues with idt/sigmatel codec

Specs: Windows XP
I too had the no sound device problem after a re-install of XP Professional... Dimension E521... First, I had no device at all under device manager. Then downloaded something off of the realtek site, which resulted in me getting "IDT high def audio codec" listed, but with the yellow exclamation point.. followed some online forum suggestions and downloaded some drivers, which resulted in the codec now being called sigmatel high def codec under device manager, but it still had the yellow exclamation - did lots of uninstall and reinstall - no luck. Finally went under properties / details / hardware ids - copied info, did a search, and several forums suggested R173209 or a R182475 but in the end these didn't work. Instead, I tried R173208, which did work. No less than 6 hours fighting this but success at hand!

For Dell machines you should only download drivers from Dell's support website, not from the device manufacturer or from anywhere else. You got lucky this time, but most of Dell's hardware requires custom-made drivers made specially for Dell, and only Dell has them.

The only exception to that rule is when you want a driver for a device that wasn't fitted at the Dell factory (eg external devices).

You could have sorted your problem much faster if you'd gone straight to Dell's website
