Object reference not set to an instance of an object

I'm totally new in Unity world, for sure I made some strange logic error.

Yes, I have the latest version of MasterAudio
and PlaylistController-Sluza2-1 and PlaylistController-Sluza2-2 this are playlist controllers.

And below are the very first errors.
Hope this will help in finding source of my problem.

Thanks for hints!

I removed all audiosource with the exception of those from the playlists, because Unity does not allow it.
 It didn't help.

And here are the settings in the Inspector:

Suuuper, wonderful great! It works! Thanks!

Confess without beating, it was me, I screwed up.

I am a minimalist, I thought it was software error, so I removed the duplicate audio source.

:-)))



I have two puzzles more.

Please explain:



1. How to random play only one sound from the particular playlist?



2. How to play the sounds one by one?

For example:

Now, after the entrance to the point "Sluza2" I have actions:

- Master Audio play sound

- And second action is: Master Audio playlist start by name


Efect is: when a player touches the "Sluza2" both actions start to play at the same time,
but I want to arrange sounds in the exact order to create story teller.


I would like to make some sounds random in the story for every point of where enters the player. Hence these my questions.

Thanks! Master Audio with Playsound event is great!
I entered the name of the group but Variation Name I had left empty and thus I have a random sound, and then at the end of playing player pass further. Jupi! :-)

And how to do:
the entire playlist is played back and then move on to the next event?

It is beyond my reach.
But I can get around this by setting a sound one after the other with the transition to the next event.
Thanks for reply!

BTW, how much it would cost to order such action from you?

Or maybe you add it at the next update? :-)
