Hi there, I've looked all over the web for an answer but couldn't find anything. Hopefully you'll be able to help! I've been using my MacBook Pro to watch DTS-encoded movies connecting it through a fiber-optic cable (with a toslink adapter). It works fine if I connect it directly to my home-theater. Now I'm trying to connect it through this splitter, in order to easily switch between cable TV and the MBP: When I do this no audio comes out. The cable TV audio works fine when connected to the splitter. The MBP goes on encoded audio mode when connected and sends audio. I've tried changing all cables (3 of them) but it still won't work. I've also tried switching inputs. Any ideas?
