Yeah the hamburger menu is auto-generated when the applet is inside the system tray. When it's not, there is no hamburger menu and its actions are only accessible using the context menu.
The reason why there is a hamburger menu in the first place is because there are two configure actions (one for the applet and one to open the Audio KCM) because we had to un-embed the Audio KCM from the settings window due to Bug 433444 following it being ported to use the multi-page KCM infrastructure.
Once we fix Bug 433444, we will be able to put the KCM back into the applet's own settings window and then there will be only one configure button which will always be visible in both the System Tray and standalone versions, and this bug will be fixed automatically.
In fact there's really no bug at all here right now since the functionality is simply... not in a hamburger menu. It's visible on the toolbar instead.
