First, sorry for my english, it can be pretty bad ! Also, thanks for the future answer, it would help me so much...!
I have a problem on Vuforia today. I'm working on a AR project right now: i'd like to scan drawing and make appeared on a phone a video with sound.
But when I scan the video on Unity, the sound just launch, without scanning anything.
I work on Unity 2019.4.23.
