"Pause on the last frame of a video" interferes with audio repeat
For the latest version of VLC Media Player (2.1.5 Rincewind), if a user goes into their preferences (Ctrl+P) and under the "Interface" section, checks the option "Pause on the last frame of a video", when/if he plays an audio file on repeat/loop one (or possibly other settings such as shuffle), the file will not repeat after it is finished; it will, instead, stop at the last second of the audio file, even though it is not a video file.
