-* Unloading the overlay for an ALSA card can stall if something is actively using ALSA - the LXPanel volume slider plugin demonstrates this effect. To enable overlays for sound cards to be removed, the `lxpanelctl` utility has been given two new options -- `alsastop` and `alsastart` -- and these are called from the auxilliary scripts dtoverlay-pre and dtoverlay-post before and after overlays are loaded or unloaded, respectively.
