SigmaTel 9250. Sigmatel SOld its codec line to IDT where the drivers got adsorbed into oblivion . (happens often)
Below is how I get crappy conexant drivers to work, dell's work the best, perhaps itl work for audio too...
here try this:dell Driver
**It will not install automatically. Itl try then say you don't have a dell. BUT it created a DELL folder in your C drive where you can point the driver search to.. theres a GRAND possibility itl work, sorry if it don't.
