volatile is a status icon which controls audio volume via ALSA / PulseAudio.

Clicking the icon brings up a volume slider. Context-clicking the icon toggles mute.

Scrolling while hovering the icon (whether the slider is visible or not) also adjusts the volume.

-c/--card: sound card ID to use

-r/--reverse-scroll: scroll volume in reverse ("natural scrolling")
