Did something change with sound?

Questions
#1

In a project I released last year, I stopped a background sound, then would follow it up with a play. Then I would pause it with a global muted variable to toggle off the sound. This was only called in

sound.stop("#happybounce")
sound.play("#happybounce", { delay = 1, gain = 1.0, pan = 0 }) 
sound.pause("#happybounce", MUSICMUTED )

This was only called after the splashscreen ended or the level was reset.

In a update function, i would pause the sounds with the muted variable as well in case the user clicked a mute button.

sound.pause("#happybounce", MUSICMUTED )

This worked flawlessly. Now, after loading the project, when i move from menu screen to screen, the background plays over itself and with each new click.

muting still works, but when its unmuted, the multiple copies then play again.

Which version of Defold did you use one year ago? Have you looked at the release notes from then until now? It would also be very helpful if you shared a minimal project where this is reproduced. I am not 100% sure I understand what’s going on.
