On my PC, the sound connections are: ASRock B75M-DGS R2.0 motherboard audio output/Edifier M1250 speaker/in-ear headphones, any model, for example KZ EDC Pro. Is there any loss of sound quality until it reaches the headphones? Is the sound card on this motherboard good enough to provide maximum performance to the headphones?

"the building"? If your pc is mangling it that much, it would be pretty obvious.
This is actually a good technical question... because none of us really know the answer without knowing the details of the motherboard and speaker, which can only be obtained by proper testing or teardown.
in-ear headphones, especially BA drivers, generally perform poor with onboard sound because 1) High noise levels 2) BA drivers have high impedance variation with frequency, and onboard sound / sound cards have high output impedance if it is labelled "line out" and not "headphone out". That being said, some motherboards / laptops do have headphone out / line out combo jacks, but even then the output impedance is a mess, so as said in paragraph #1, none of us really know without testing.
As for the headphone jack on speakers, often (I HOPE) it is positioned behind a buffer behind the volume control so you can adjust the headphone's volume, but I'm pretty sure there are oddball products which connects the headphone out directly to line-in. In any case, the output impedance of the headphone out is often again unspecified.
Ultimately, if you can't hear a difference, it's good enough. Even in some cases where you can hear a difference, like using my old PSP's headphone out with BA IEMs, I can live with it. Especially considering any "proper" solution to fix tiny problem will cost more than your M1250.

If you aren't hearing noise (hum, hiss or whine) during silence and if your headphones/earphones go loud enough, the quality is probably better than human hearing.
Some headphones & in-ears are more sensitive (louder) than others so some may need something with a more powerful headphone amp.
The audio can be "digitally perfect" (or nearly perfect) until it gets converted to analog. EQ, tone controls, or other "enhancements" can, of course, alter the sound. Most software media players have EQ. Windows has some "enhancements" and your drivers may have some effects or adjustments.
I had a laptop that had settings for internal or external speakers and it would cut the bass when set to "internal speakers" (to minimize distortion). That setting didn't change automatically when you plugged-in headphones or external speakers and you'd hear the loss of bass. (My current computers don't have that.)

What signal processed by what chip particularly in what pc?
Probably doesn't particularly matter....So what's the particular issue? Doubt it's inherent sound quality due to spec of components....sequence: motherboard audio p2/edifier m1250/kz edc pro
