When is the "default alert sound" played?

Hi there,

My app plays the "default alert sound" when received "Remote Push Notification" and other timing.

I understand the "default alert sound" plays when received "Remote Push Notification". However, it plays at some timing which is not the timing my app received "Remote Push Notification".

I have no idea what makes the "default alert sound" play.

Is there any trigger to make the "default alert sound" play other than receiving "Remote Push Notification"?

Self-resolved.

It seems other push notifications are sent from APNs, which I did not know.

Sorry for disturbing you.
