my system: ubuntu 16.04 suite nvidia gtx 1050 ti
Usually when I run a newly installed program, it has no sound. However, this is simply fixed, I just run it and open the pavu-controll to select as the source for this program my graphic card.

Why is it so? What is different this time? How do I get the sound to play?
It looks like this, notice no GPU to select:
