I have a Room PC connected to my CX8000 using a DisplayPort to DVI cable. I have a 3.5mm audio cable from the green, audio out port of the CX8000 going to the audio in port of my TV. This allows Lync sounds to be played out of the speakers of the TV. I am trying to get the sounds of the Room PC to come out of the same speakers. I have tried plugging another 3.5mm audio cable from the green, audio out port of the Room PC to the blue, audio in port of the CX8000, but no sounds come out.
