really strange, I have no chance to select any music source for my slideshow. If I translate from ym German Lightroom cc it stalest "no music selected" and above this line it says duration: 0 and to the right a plus sign.
Clicks on any of theses are do not read to any reaction.
If i do a right click on "music" (where you can select if you want to the see there single parts like options, layout, title etc...) music has an asterix behind its name "music *"
Searches revealed the same question, but no answer...hope somebody here has an idea!
May i know when you click on the "+" sign what happens.?
to answer the question: Nothing happens.
But I found the solution.. I did not recognize the slider on the left slide which enables/disables audio. No it works.
I think it's a bit strange to deactivate audio even if no audio is selected..
Anayway, all ok now.
