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.
