I just got a used Sony Mini System (60 CD changer, cassette, radio, Game, Video functions). On the back it has an toslink digital audio out port. I was hoping to get digital audio from my PS3 to the stereo but it seems I can't cause the stereo is digital audio "out" not "in". This may be a stupid question but is there a way to reverse that?? It has two sets of analog audio inputs so I'm using that but was really hoping to use the digital audio. Any options out there??
