Alarm (off) not executing the same power off as the remote

Hi,

i'm using IR blaster which works fine. When you start to play a song it will send a signal so the AMP is also powered on. When you turn of LSM with remote or on phisical button it sends signal to power off AMP. This all works fine.

Problem comes with LMS Alarm. When alarm starts the signal is pushed trough IR blaster so the amp turns on. When the alarm ends LMS does not send a signal trough IR blaster. Why is that?
