Sound icon disappears from Tint2 after click

view full story

http://crunchbanglinux.org – I tried to install mplayer from Synaptic before later realizing it comes preinstalled(?).While the install was in process (I assume there were additional files), the volume icon disappeared from my tint2 tray.   I can still access the sound controls from super+V, however, the icon is gone.  Restarting tint2 does not bring it back.I rebooted, and the icon reappeared.  However, once I click it, it vanishes.And ideas? I am guessing something with the mplayer installation may be the culprit but I cannot imagine where I would start.  Thanks for your assistance, denizens of (HowTos)
