When an audio CD is inserted in my computer, an icon named Audio CD appeared. Open it would open an window "Audio Disc - File Browser", which contains files 'Track 1.wav' to 'Track 15.wav' Double-click on each one would open the Movie Player, and a message said: 'An error occurred' 'No URI handler implemented for "cdda".' Movie --> Play Disc 'Audio Disc' in the menu greyed out, too. However, issue 'totem cdda://' in terminal would let the Movie Player play the first track, and only the first track.
