Black screen issue: wanting your opinion

Hello

I've searched for this issue and seen all kind of reasons, but my own analysis doesn't seem to fit any. So I'm kind of desperate. I'll make it clear and simple:

Issue:
- "Random" black screen" with:
-- Infinite sound loop

I didn't find the right solution from the internet.
