PowerMac G5 Tower - TOSlink OUT to Analog Powered Speakers
I have a PowerMac G5 tower and need to use the TOSlink S/PDIF Optical Out Port in order to get sound. The ONLY reason why I'm taking this route is because there has always been a problem with the analog out on my system, despite the fact that I purchased it brand new from Apple, where something in the port occasionally "pushes" a mini stereo jack back out. So there has been a problem in manufacture here. When the jack is pushed out, the sound to my analog powered speakers is altered/crappy or nonexistent. So I have sought to circumvent the problem now that it is out of warranty by using Digital Out.
The steps I have taken are to plug an S/PDIF cable into the TOSlink Out port, into a Gefen Digital to Analog Audio Converter, into a split RCA analog cable, which at the other end is a mini stereo end and into my analog, powered speakers. I now have no sound whatsoever. What could be the problem in what looks like a rather simple hookup?
