Confirmed on Gnome Shell too. And looking at the source code I can't find an icon at all. In fact I can't see any icons present in the PulseAudio source :)
Please log a bug with upstream: https://bugs.freedesktop.org/enter_bug.cgi?product=PulseAudio You may also want to find the Ubuntu package for your current icon set and log a bug against that package too. ** Changed in: pulseaudio (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1736142 Title: No app icon for qpaeq in cinnamon environment Status in pulseaudio package in Ubuntu: New Bug description: This bug affects qpaeq from pulseaudio-equalizer package.
