What data are you sending to the audio player? Are you able to play it manually, or is just the autoplay failing to work? It seems from the error message like the data the audio player is being asked to process something it cannot process.
Is there a “start playing” action for your plugin? You can do a When condition is true workflow with the condition Page is loaded (entire) to trigger the audio player.
Or maybe the plain old Page is loaded workflow would do it
Also strange thing is that when I upload page in “normal run”, the bug appears.
If I upload the page in “next step” of debugger, the bug won’t appear.
So I guess maybe it’s due to some timing or something ?
I think this could be the reason yes. I tested on Chrome : didn’t work. I tested on Firefox : worked (after I authorized autoplay in browser configuration)
try this: create a custom workflow when you put the "Play audio x step, and when the page is loaded, try a “Schedule custom workflow”, then try 0 seconds at first, then 1 second, and 5 seconds… try longer till it gets right
Still doesn’t work though. It’s weird because when I run the page load normally, the bug appears. But if I run the page load step by step with debugger, it then works out.
