I have connected 2 camera's with mics to my PC: one Aver VC520 Pro2 by network and other Microsoft LifeCam Cinema by USB. I want send sound from Aver VC520 Pro2 to TV witch connected to PC by HDMI, and sound from Microsoft LifeCam Cinema send to my headphones. How can I do that, because when I connect all of the to PC, I hear sound from both mics either per TV, or per Headphones, but not separately.
