AFAIK VT1708S are installed on motherboards. Then it is most likely that the back stereo output and the front stereo output are connected to the same DACs in your computer. So, PulseAudio sees them as 1 stereo output. You can tune Linux such that the speakers and the headphones will use different DACs. (Your audio controller has 8 DACs.)
