CMedia control panel always appeared as sandoxed

How to prevent system program from “protection” at all?
I already added xonarhdav.exe (I use Xonar HDAV) to trusted files for Defence and Sanbox, but it is still sandboxed.

Make sure it is not at the same time in Unrecognised Files.

Please try the workarounds as described in App. is not working correctly, but does not seem to be s/boxed. What to do? [v5] and see if that brings a solution.
