Hi, 

See our tutorials here https://sonaar.io/docs/mp3-audio-player/

To enable sticky player, go to wp-admin > mp3 player > settings > sticky player and select playlist post in the first option (Load Sticky Player on your website) 

You can modify the sticky footer player in WP-Admin > MP3 Player > Settings

What does not work or does not seems compatible exactly? Can you send me a screenshot ?

Hi,

add this to your custom CSS (in WP-Admin > Appearance > Customize > Additional CSS):

#sonaar-player {
    left: 0;
}

This will make the sticky player fullwidth.

You can also move your red arrows up when the sticky player is activated with:

.continuousPlayer-enable .scroll-up {
    bottom: 158px;
}
.continuousPlayer-enable .scroll-down {
    bottom: 122px;
}

Auto-play audio when your page loads is now banned by most desktop and mobile browsers including Chrome and Safari. This is what we call a "Auto-Play Policy". To play audio in a web browser, the user has to interact with the page before audio can play. Interactions is something like clicking a menu, a button, scroll down the page, etc.

The closest thing you can do is to automatically fire the sticky footer player when the page load and then, users will have to click play. To do it, edit your page and select your playlist in the Music dropdown. See screenshot: https://d.pr/i/ouq7Ay
