Description: Volume management daemon for Xfce 4
Xfce4-volumed is responsible for making the volume up/down and mute keys of the
keyboard work automatically, and uses the Xfce 4 mixer's defined card and track
for chosing which track to act on. It also provides volume change / mute toggle
notifications if the notification server used supports x-canonical-icon-only
and x-canonical-synchronous notifications.
Yes, it is xfce4-volumed process to eat the 100% of cpu sometimes, but removing it doesn't seems a solution of the bug.
