Ah, here’s what I see:

• when I start the game, no sound
• when I click on the background, the background loop plays once
• when I click on the “next” button, there’s still no background music
• if I press the left-arrow key on the keyboard to go back to the first card, the background loop begins playing, and loops properly

From the documentation, under Web-Decker and Native-Decker:

Most web browsers do not allow programs to play audio until the user has interacted with a page, so any play[] commands issued before a user has clicked, tapped, or pressed a keyboard key will have no effect.

I think this is what you’re bumping into, since your deck tries to play audio when the first card appears. The simplest workaround would be to also start looping the sound on the second card, so that whether somebody’s using Web Decker or Native Decker, they get the background loop eventually. A more complex solution would be to add a pre-title card that the user has to click through to get to the title card.

For the record, I'd strongly recommend updating Decker.

v1.54 is over 8 months old; we're up to v1.61.
