Some motherboards, such as the Gigabyte Z390 Aorus @amirm reviewed, have dedicated speaker out and line out jacks. Others, such as my AsRock Fatal1ty Z170 Gaming-ITX/ac only have a speaker out. I've done some googling and some sources say that line out and speaker out are the same on PC motherboards and others say that speaker out outputs a higher voltage signal, but no real consensus or testing that I could find.
Is it an entirely case by case bases, and is there any real difference between the two, for example, when plugging into a headphone amp?
