Otherwise the audio will loop continuously...
I r-click on the expando and uncheck "loop" and it stops at the end of the file.
Normally that would apply. However in this case left-click *and *right-click both start the audio. No option to not loop it (when playing from a post). It does work for context and comments though.
This is the post you can test it on: https://poal.co/s/RealWhatever/331164
