A question on a small working code.

[jphoarau]

I have a question. Can anyone explain to me why I have to click in the main browser window to hear the sound?
Below is the code which apparently works very well, apart from this small detail. What did I forget? Thanks in advance.

Code: Select all

Global Start = ElapsedMilliseconds()

If InitSound()
  Debug "initsound MainForm OK"
EndIf

#Sound1 = 1

Procedure TimerEvent()
  Debug "Elapsed time in ms: " + Str(ElapsedMilliseconds()-Start)
  PlaySound(#Sound1)
EndProcedure

Procedure Loading(Type, Filename$)
  OpenWindow(0, 0, 0, 100, 100, "Timer", #PB_Window_Invisible)
  ;SetActiveWindow(0)
  AddWindowTimer(0, 0, 1000)
EndProcedure

Procedure LoadingError(Type, Filename$)
  Debug Filename$ + ": loading error"
EndProcedure

BindEvent(#PB_Event_Loading, @Loading())
BindEvent(#PB_Event_LoadingError, @LoadingError())
BindEvent(#PB_Event_Timer, @TimerEvent())

LoadSound(#Sound1, "./res/Sounds/Recording_10.mp3")

The AudioContext was not allowed to start. It must be resumed (or created) after a user gesture on the page.

The ability for sounds to play has to be triggered by a user action on the page. This is incredibly annoying, but it's a limitation of the web everywhere. Part of me gets why, but it's still annoying when you're making an application that uses a lot of sounds.

All right. I don't understand why, but it is not an error from me. I am reassured. Thank you.

You're most certainly not the only one that doesn't understand this. We can run any javascript we want on page load... unless it plays sounds?

Yes. Perhaps, one day, I will understand? But for now, I don't even ask myself the question.
