I have a Toshiba laptop with S/PDIF out. The S/PDIF out is shared with the headphone out port. I bought a 75ohm coaxial cable and a rca -> 3.5mm minijack convertor and hooked it all up to my Creative Playworks DTT3500 system. I enabled digital output on the laptop etc, but no sound! Nothing! Can anyone point me in the right direction, does what I have done sound right? I know next to nothing about S/PDIF. I have my PS2 connected to the same sound system with an optical cable which works brilliantly so I presume the sound system is not to blame. Any help is greatly appreciated.
