I am an Itch user and i noticed that’s happened to me too lately. I’m a bedroom/whatever-room-my-daughter-isnt-destroying-right-now-hobbyist (gotta love two year olds!)
i was thinking it had more to do with me overloading the software on an admittedly older PC (dell xps m1530)
when it happened to me the sound stopped, but the track was still playing and it was almost as if itch forgot to load the rest of the track and went “crap hurry get the rest of the song up” and it would cut back in like nothing happened…
dunno how old your mbp is but im sure its gotta be more stable than my system!
