over the sound of the card has been written much. Therefore, I leave this way with my vote.
I have finally found a sound card that (etc. clacking of the loudspeakers) makes no noise during power off the PC. This also applies to the standby mode.
Here a manufacturer has once been thinking. The speakers are separated via an integrated relay in the sound card from the sound card.
Furthermore, the installation was Windows 8.1 64bit without only one problem.
Just perfect!
