PX4 plays undefined notification tune

Hi everyone!

I just flashed the latest stable PX4 to a NXP HoverGames drone and it plays a notification tune that is not defined in PX4-Autopilot/tune_definition.desc at main · PX4/PX4-Autopilot · GitHub.
I noticed that it is played 12m 10s after booting consistently.
QGroundControl doesn’t show any notification.

Can anyone help me with this?

Noone has ever flashed a completely standard PX4 and noticed what I noticed?
