Lenovo G400s Dolby does not work after BIOS update


I need some help, my dolby v2 on lenovo g400s doesn't work at all.

i just update my bios from 7BC21WW (V1.05) to 7BC38WW(V2.04) it causing my dolby doesn't work and swapped the function of f1-f12.

i managed to enable the function of f1-f12 through bios config

but i still can't fix the dolby audio and i'm already reinstall the driver but it doesn't affect anything.

maybe anyone have the bios version 7BC21WW (V1.05) so i can revert it.

or any suggestion?


thank you so much.

Did you check for an updated driver for the sound?
