So I've been struggling to get this combo to work with my PC and am on the verge of giving up on it. I currently have a Vizio Soundbar hooked to my PC through a Digital Optical cable (Toslink). My soundbar has the sub-woofer hooked to it with a cord that came with it (not quite sure what cord it is tbh). This setup worked when I was in my old house when it was hooked to my TV, but now that I want it for my PC, it doesn't work. I'm not sure if its just a software config error or what, but I'm stumped. Audio was never my best area! The sound to the soundbar works fine, but there is nothing going to the sub-woofer. Any suggestions?
