I had the same problem and I needed to go to this bug report to understand that adding the indicator-applet is the thing to correct this bug.
I think that, the description of indicator-applet should be updated to add something like: "... need your attention on the desktop (volume, instant message, emails, ...)" -- Volume control icon not present after upgrade to Lucid when app indicator applet has been removed by hand in Karmic https://bugs.launchpad.net/bugs/552221 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
