I need link for Dolby Advanced Audio (v2) for GP Pavilion g7 notebook pc.

Hello ! 

Here's my issue: I have in my posession a HP Pavilion g7 notebook pc. The problem is that allthough the speakers on the laptop says << DOLBY Advanced Audio>> , i don't have the Dolby Advanced Audio software.

I would like to ask if that is normal , or it is not.

In the case that this is not normal , i would like to ask for a link to download the Dolby Advanced Audio software for my HP notebook.

Please note that my notebook currently runs Windows 8.1 .

Thanks in advancde,

your HP member.
