Hmm, this sounds like Pulse is dying and not restarting properly. I did notice something similar at a time in this cycle when there was alot of work going on in dbusmenu (the library responsible for that button) but not for a few weeks now.
Could you confirm the bug by: 1. When the menu is working as expected, open a terminal and type ' pulseaudio --k' 2. Check the menu to see if the bug is visible.
