SUMMARY

When the option ¨Pause media players on suspend" is selected, if SMPlayer is already paused, when the PC is going to suspend the media player (smplayer) starts playing. When returning from suspend the media player is also playing (even before unlock the session).

On the other hand, if the option ¨Pause media players on suspend" is unselected, the SMPlayer remains paused when the PC is going to suspend.

However, if SMPlayer is playing, the ¨Pause media players on suspend" works as intended (SMPlayer is paused on suspend)


STEPS TO REPRODUCE
1. Enable ¨Pause media players on suspend" in the Advanced Settings of Power Management
2. Start playing any media file with SMPlayer
3. Pause SMPlayer
4. Suspend the PC

OBSERVED RESULT
SMPlayer start playing just before the PC enters in suspension
When returning from suspend, SMPlayer is also playing


EXPECTED RESULT
SMPlayer maintains the media in pause
