Hi corrinarusso, thanks for your reply but it’s what I’m looking for. I only want to play an audio file (audio.mp3) directly from the homepage and I don’t want to add another script in the header (like this one https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_audio_play) if it’s not necessary.

Yes – you don’t need anything else, just upload the file like this and it’s done :
