Sonic studio doesn't come with the Realtek driver, this seems to be some bad info spreading around the net (and by asus)
The original windows install your laptop came with had a folder directly on the C: root called "eSupport", in there was another called "eDriver"
In the eDriver folder is an application called AsInsWiz.exe, its equivalent to those driver CD's that used to come with laptops and/or motherboards.
Running that app will do an auto-install of all the drivers that came pre-installed as well as the applications including SonicStudio.
I compressed that folder that came with my GL702VS and hosted it on my dropbox account. would you like a link?
