Blocker - Alt+Tab causes sequences to break audio or not play at all

General Issues and Bug Reporting

When playing a sequence at the beginning of the game, or at any point in the game, if the player is Alt+Tabbed the sequence will restart its audio while still playing from the continued spot in the timeline (breaking audio), or sometimes even worse it will not play at all (game logic will function, but the sequence will be as if it never played)

I haven’t done much testing to fully confirm this, but I ve seen another report about it a while back. If someone can help post more information so we can report this better, feel free.

What I ve noticed is that in my game, I have a fade out track at the beginning which fades out and the game will get stuck there if I am alt tabbed then go back into the game (after the cutscene is finished), but the sequence will not be playing.

seen this exact failure. when the window loses focus the audio device gets interrupted but the sequence timeline keeps going, so on return the audio restarts from the current position while the fade track already passed. that is why it looks stuck after the fade.

practical fix: bind to the application focus delegates and pause the sequence on focus lost, resume on focus regained. also test fullscreen exclusive vs borderless since they behave differently on alt-tab, borderless is usually less destructive.

for unattended builds this is also why kiosks lock focus entirely. kiosk lockdown toolkit from fab handles the alt-tab and system key blocking side if you ship somewhere visitors can touch the keyboard.
