Problem: Cannot access sound menu after 3 hours of system idling or stand by.
How to replicate it:
Install any Asus outdated Graphics Driver or AMD Catalyst 13.4 or latest driver.
Install a Asus HD7970 Direct CU II Top Graphic card
Install a Asus Xonar Essence STX sound card and default ASUS latest driver
Install Windows 7 Pro 32 bit edition with Sp1.
Make sure all of it is running.
Then leave your PC for 3 hours.
Then go to Control Panel>Sound Panel>Adjust sound settings menu!
You cannot enter adjust sound settings menu (The Menu not even popping out) (No system responsiveness alerts, no nothing!)
Solution: This is not a window bug, it have to do with the Graphics card audio settings conflict with your sound card! Test it out for GOD SAKE! STOP BEING IGNORANT AND SPOON FEED !! ASUS! grrrr
