I know the code has the "muted" tag in the code so it should not play the audio. But when I remove the tag on both .liquid files, on my edit theme section I can hear the audio and see the video as well, but if I save and visit my site www.igioiellidellacorona.com the video does not start at all, same for the audio.
Also, sometimes when I tried to fix this error I've noticed that the video sometimes start on chrome and not on Safari and viceversa. It must be a code error in my opinion.
Thank you if you've read it all, I'm hoping someone will write me some codes to fix this.
