whyjack, mine has a Realtek Audio Driver. Did you try what @TairikuOkami said to use? Driver Easy Free? Also, does your PC have the Toshiba Service Station? That will also find drivers and updates for Toshiba computers. It is similar to HP's HP Support Assistant. You could also use Driverscape. But, make sure you type in your product in Google along with Driverscape. I hope this helps!
