Hi,
This is not specific to one board but all boards with Realtek 40XX sound chip.
Did any of you notice that when you boot with standard USB 2.0 onboard sound, Windows will boot an average 10 seconds faster then when Realtek/Asus drivers are installed.
I tested this theory about 20 times and the results are always the same. Windows will boot an average 10 seconds slower with Realtek drivers installed.
Sometimes, the boot will be normal as if no drivers are installed, but it doesn't happen often.
Thanks for your comments.
