If there is no sound card installed then there is no need to disable sound and music, it's already disabled. The issue comes when a sound card is installed and sound or music device selected. Sound cards use interrupts in order to work, and that causes sound code to be executed whenever the sound card requires it, adding more variability to the results. Here I'm testing only game and rendering code, so better with sound/music disabled.
