I installed the Realtek HD audio driver
from the ASUS download site (P8Z68-V Pro MB) and all was well until I installed an MSI 560TI video card and let it install the Nvidia HD Audio drivers
. The problem I have been chasing ever since was the Realtek HD Audio Manager popping up after the system exited extended sleep state (overnight). After much trial and tribulation and several Google Searches I concluded that the Realtek/ASUS HD Audio driver was conflicting with the Nvidia driver(s).
I did what suggested on one of the sites and that was to delete the Realtek HD Audio drivers and just let Windows 7 install the default Microsoft drivers. Problem gone! Now I am curious, what did I give up and if I install the latest Realtek driver for Windows 7 64-bit (v267) from the Realtek site will the Nvidia conflict return?
