Hello, I really need your help. I have a Logitech Z506 5.1 surround sound system but the motherboard I am interested in buying which is the ASROCK A320m-Hdv AM4 only has 3 ports which is the Mic port (pink), Audio out (green) and line in (blue). However, the Logitech z506 5.5 speaker system has a black, orange and green cables. My question is, if I was to only connect the green cable of the speakers to the green port of the motherboard would I at least be able to get 2.0 stereo sound? I am not interested in buying a sound card just yet because I am working with a really tight budget.
