Hey guys, looking for some help with this issue. I have a late 2007 (2.16ghz C2D) macbook and have been using a mini toslink to toslink cable to connect it to my z-5500's for about 2 years now. All of a sudden yesterday the connection stopped working. I have tried my backup cable and a standard cable with an adapter to no avail. All cables have red light at the end when plugged into the macbook. My xbox still plays fine through the speakers as well. Any help is appreciated.
