Icons unclear, possibly improve them?

I alwyas had issues checking for locked or muted, only the highlight is changing while it would be much better the icons would change to "unmuted" and "unlocked". With some themes it can be hardly noticed.

Well, it's related to the Qt style and/or icon set. Don't blame LXQt for Fusion's shortcomings ;)

I meant icons like in the volume plugin, no idea if that is doable here:

The use case is different in pavucontrol-qt. Here we have two other icons, at least one of which doesn't have a counterpart, and so, changing the icon on switching the toggled state would create an inconsistency.
