MacPro4,1 optical out -> Avid HD I/0 not working
Hi,
I'm trying to connect the optical S/PDIF (Toslink) output of my MacPro to an Avid HD I/O. I wanted to use the enclosed HD I/O's optical ADAT input. Unfortunately I'm getting no audio signal at all. Not even a crackling occurs. I also tried with the optical inputs of my 192 Digital interface and with my ProFireLightbridge which is connected to my MBP. The ProFireLightbridge produced at least some crackling ... but still no audio. I googled a bit and found out that for some people it's working and for some people not. Are there any specific options/settings I could try ? Additional info: All my 4 Avid/Digidesign interfaces are clocked by a BigBen. Also one PC (using RME Multiface HW - routed back via Lightpipe to a 96 I/O), another PC and the ProFireLightbridge (routed back via Lightpipe to 192 Digital I/0) and my Roland vSynth GT (clocked via SPDIF from BigBen and routed back via SPDIF to the 192Digital I/O). Everything works fine except the Mac's optical out
