I have an Toshiba Satellite Z830-10T and just upgraded to Windows 10. Most things have worked, except for the Dolby audio driver. I keep getting the following message:

The current Dolby audio driver version 7.2.8000.17 and the software application expects driver version 7.2.7000.7.Please install a valid driver and software application combination.

I've seen on a different forum thread that someone said go to http://win10upgrade.toshiba.com/swup...=en&country=GB. As the Z830 isn't listed as a model, the person suggested trying the Z930 instead. I tried this but it didn't work.

I've tried finding the right driver online, but cannot find it.

Could someone advise how to fix this for my laptop, the Z830?

with thanks, Julieanne
