mac mini problem

[blior32017]

I created this sort of computer problem that when I connect headphones or computer speakers I hear the songs sort these bugs and such kind of a strange noise
The problem is just connecting the computer's 3.5 inner loudspeaker I hear fine and everything is normal
I brought you a video I recorded the sound card so you can hear my problem:

Sorry for my english hope you understand the problem by the video below

Am I understanding you:
It makes this sound when you plug in speakers to the headphone port.
It does not make this sound using the speaker inside the computer.
Correct?

That sounds like a real problem with the audio output system, that Apple should repair.
