I want to play an mp4 file when my account is logged into. How can I do this?
It should be noted that the file also has video, so I only want the sound to be played, and not the video to be shown. And I also don't want any program to be visually launched, so for instance if on every startup VLC Player launched playing that file that would not be acceptable.
I am running Ubuntu GNOME 15.10 with GNOME 3.18.
