One option is to run a mute and stop-playing command immediately
on screensaver interaction.

For XFCE4, that's as easy as adding a panel object which runs an
application, pointing that at a script, and adding an
appropriate icon. Install xmacro.

~/bin/quiet-and-dark

#!/bin/sh
#not actually tested
echo 'KeyStrPress XF86AudioPlay KeyStrRelease XF86AudioPlay' | xmacroplay :0
echo 'KeyStrPress XF86AudioMute KeyStrRelease XF86AudioMute' | xmacroplay :0
xscreensaver -command activate


You can also assign it to run as a keyboard shortcut.
