So I got my macbook pro here my Onkyo 3009 over there and my new toslink cable with adapter and, darn it, if the sound just doesn't want to travel from the computer to the receiver. So far I've gone into the onkyo menu and changed the digital input on the PC tab (the pre-set I plan to use for........well......my PC) so that it is supposed to be receiving digital input from the corresponding optical port that I plugged the new toslink cable into in the back. Turn music on, cue receiver, and I got nothing. I currently use toslink in the other optical port for my TV so I turned the TV on and got it going so I could hear sound, unplugged the TV optical and replaced it with the computer optical. Still nothing. Lugged my old logitech Z-5500 system out from the storage room and plugged it in and reconnected the control module with no speakers. Plugged the new toslink into the control module and voila the subwoofer springs to life. So now I know the receiver works. I know the toslink cable works and is delivering audio through it. I have no idea why it wouldn't be delivering audio to the receiver. Any ideas? I hate to think that A) I bought this cable and adapter for nothing and B) I'll have to go with plan B and that involves spending more money. No me gusta. Help please.
