I’ve got Toshiba Tecra A8-185. It's model PTA83E.
The problem is that I installed Windows 7 Ultimate and although all drivers are working correctly, the sound system isn't.
System is saying drivers are working correctly and I can see that it recognizes sounds on a volume bar.
When I connect headphones it also doesn't work, though microphone is working. I got the newest drivers from Toshiba website and from Realtek website (HD Audio). I was also trying to install AC'97, but it's asking me to confirm the drivers during installation, cause they are not digitally signed, but it keeps on asking, until I won't disagree to drivers.
So I know for sure it's a software problem. But I don't know what's wrong with the drivers.
Please help! You can also mail me, if anyone has any solution.
