Is there a way i can add title screen music with the new ui system

so i was fiddling around in unity with the ui system and then i wanted to add some title screen music i added a 3d audio source around the canvas and played and there was no sound

Make it a 2D sound. Its not the UI (well kinda since the UI is huge in scale).

In addition to what calmcarrots said, there has to be an AudioListener present o the screen. I think the Canvas does not have one by default. Try attaching an AudioListener to an object, see if that fixes it.
