No Banshee notification area icon in Gnome 3 classic session

After installing Ubuntu 12.04, I have a problem with Banshee: it doesn't have a tray icon. I know about the tray-icon-plugin, but it's not working:

I'm using Gnome 3 in classic mode. In gnome-shell Banshee has an icon. How can I get the tray-icon to work in a classic session?

You can add the notification applet to the gnome-panel as shown in the picture.

To add, ALT+Win and right-click the gnome-panel to add the notification applet.

However, banshee is fully integrated in the sound-indicator, to perhaps the use of the notification icon is not required.

Install package: banshee-extension-appindicator

sudo apt-get install banshee-extension-appindicator

This package provides integration for Banshee with Application Indicators, which is a replacement for the notification area in Ubuntu, as a way to add menus in the panel.

REMEMBER to enable it as extension from banshee's preferences.

Open Banshee UI. Go to Menu Edit > Preferences > Extensions.

There are several groups like communityExtensions,ContextPane...

Go to Utilies group. Notification Area sound Menu integration are the required options.

On my laptop these 2 options are exclusive. Notification Area gives a banshee icon in notification area. But has only one option to seek the play bar by hovering the mouse over the icon.

All other options are present in the menu on left click.
