Yesterday Realtek released a minor update of it HD audio drivers.

This is very unusual since they normally release major versions only. Maybe there was something buggy in the previous Vista release.

Unattended usage:

setup.exe -s -f2<path\LogFile> -z[-rp<path\LogFile>]
example:
setup.exe -s -f2C:\mylog.log -z[-rpC:\RHDSetup.log]
