Uninstalling Realtek Audio only works until windows update decides to update it.........
This is a method that I found on the Net that works, Windows update does not show Realtek Audio anymore.
I'm not sure if this affects the sd card reader since I dont use it?

Here's how to permanently get rid of the Realtek driver:
① disable, disconnect or unplug any internet connection to prevent Windows from reinstalling the driver,
② uninstall "Realtek High Definition Audio Driver" and restart to make sure it's gone,
③ go to C:\Program Files and create a new folder called "Realtek",
④ open the properties dialog, go to the "Security" tab and click on "Advanced",
⑤ click on "Change Permissions", then "Disable inheritance", and in the new dialog select "Remove all inherited permission from this object",
⑥ click on "OK" and "Yes" etc. to apply the changes.
