Nothing in /usr/share/doc/xserver-xorg-input-libinput/ gives any clue on how to use it. There is no man page I can find. There is /usr/share/X11/xorg.conf.d/40-libinput.conf but again no clue on usage. I think the workaround of using the mouse on pavucontrol or gkrellm-volume will have to do for sound control. Thanks!
