trouble with audio editing

hi all
when I clic on a audio a Windows is opening

i want to edit markers no problem

between two markers i want to listen this zone for a quick control , I clic on it and no sound !! a short clic or a maintain clic no sound !!

So my question is : how to do in order to have a sound in a zone between two markers ?

check control room and disable it. vst connection - studio - control room( blue sign if active).
