Comment 6 for bug 1776748

Walter, on ~/.config/lxpanel/Lubuntu/panels/panel, the plugin type indicator has two preferences, sound and apps, when sound enabled only sound icon is shown, when apps enabled the network icon and other apps (like cliptit, multiload, etc) is shown; on other hand the plugin type tray shows the battery icon and network icon.

There is no real solution, if tray is removed battery icon is lost, if indicator is removed sound icon and other apps is lost, only if you disable other apps on indicator preferences in order to show only the sound icon, but you would lose the feature to add apps like clipit and multiload.
