What is this on my gig page?

[reformata_av]

On the gig page where one can select gig photos to look at the very last thing is an headphone icon. When clicked it seems to be a media player for audio.



Is this something placed there for future implementation to share work examples or is it supposed to be already active? If active, how do we use it as I see nowhere in the gig set-up to be able upload any kind of audio.
