I have a Latitude D800. When I first received the laptop, the volume buttons on the keyboard were properly working. They suddenly stopped to work and I could not understand why.

I've done almoste everything I could, ncluding:

- quickset update (1.2.6)

- Sigmatel Audio board driver update (6.14.01.3794, A06)

but no success.

I've found that if I disable and then enable back the "Sigmatel C-Major Audio" device from the Device Managarr (I have Win2K SP4) the volume buttoms start to work properly. BUT.. when I reboot the pC they do not work any more.

 

Any suggestion?

tnx
