After recent update I am not able to change the volume using the keyboard button. It used to work fine earlier but not anymore. All other buttons (Play/Pause, Brightness, Wireless-Enable/Disable etc) work fine. Moreover there is speaker in the notification area. It used to be there before.
In System->Preferences, there is no option to control sound preferences.
Thanks

You don't mention what version of Ubuntu you are running but if it is a version up to 10.10 go to System -> Preferences -> Sound and a dialog box like below should pop up.
If however it is a Natty beta version then select the applications tab in Unity and search for Sound.
Ensure you have the Internal Audio selected and try a test on your speakers.
You should also check your start up programs and ensure Pulse Audio is selected by going to System -> Preferences -> Start Up Applications - or the applications tab in Unity and search for start up applications and ensure Pulse Audio is selected as below;
