Play/Pause problem

Hi,


When I press PAUSE and after a while PLAY the music:
1. stops
2. track goes about 1 second back (rewind) and
3. music plays again
so.. one maybe two seconds of every track is being repeated when PAUSE/PLAY pressed

and It doesn't matter if I set audio output for hdmi, aux or BT,
It is always the same,
I play local mp3 files (I also tried wav)

Is this a bag?
or any player feature which maybe switched off?
Is there any option to change in kodi advancedsettings.xml to fix that?

I'm using LibreELEC 8.2.5 on RPI3 and Kodi 17.6.

Regards,
MM
