You want the 2 hdmi cables from the consoles to the hub + the dvi cable from the comp. Then the corresponding hdmi phono plugs need to go to the amp--->speakers if your amp doesn't accept 4phono inputs you can use an adpater to convert 2 phono into 1 phono and plug both blacks into and both reds into a different adapter then into the amp. Alternatively you can put all audio through the computer via line in and a phono 3.5mm jacks but this may cause slight lag (personally I wouldn't mind)
