Should I use Front or Rear headphone socket? (Crosshair Hero VII).

Level 7
I've looked online etc and seem to have found conflicting information as to what headphone jack is best to use (best quality), out of the front and back - any advise with reasoning behind it would be great. (I must admit i'm not sure what the difference is between the DAC and the Codec).

This below is the information on the motherboard, along with a few other bits of information i found regarding the components.

I've always used the rear headphone jacks because using the fronts always gave me interference.
