i got this pc in the start of the year. i bought an 5.1 speaker and all seens fine. when any audio is played no sound come out on the front speaker even if the game/progam supports 5.1 audio. that also happen with my headphones when i plug into the front or back jack the sound of the character voices, gun sounds, all sounds that come from the front dont work. an really bad exemple is: if in minecraft i open an chest in my front, i cant hear it, but if someone opens it on my right/left it sounds normal. that happend on my old computer that was set up by the same guy.
