Thread Starter 

i am using headphones on my headphone jack and in the realtek hd audio manager i can change it to whatever i want including line out, if i do set "line out" i will get better quality or something? or it is preferably just leaving it as "headphone out"? also the changes are made instantly? or i need to reboot?

 

i just noticed changing from headphone out to line out decreases the volume, is that good?i am getting optimal signal and headphone out was just an ear cancer machine? how it should be? can you tell me?

Line out has a set volume level typically safe for feeding other devices.  How each is wired, isolated from noise, and built can vary wildly so choose whichever sounds the best.

so i am not getting degraded signal by using line out on my headphones? i thought headphones needed the headphone out so they can be amplified? that means by using line out they are not being amplified?

 

whats the correct one that i should use for headphones? line out or headphone out? for best sound quality and fidelity? i heard by using headphones out it degrades the sound quality and other things and line out does not but what do you guys think? what is the "must use" option? volume doesnt matter but sound quality and fidelity does matter.

Realtek soundcard outputs contain amplification circuits for driving headphones. Since every amplifier introduces some amount of noise and distortion, these amps can be disabled when they aren't needed (e.g. when user connects some external amplifier to the soundcard).

"Headphone" enables these amps, "line-out" disables them.

If the only difference is volume and you don't mind lower volume, you may keep it at line-out. But on my laptop I had to use "headphone" because "line-out" killed all bass.
