And yes, like you, I search the web for the toslink cabling specs. The only thing I can think of it is a very thin cabling without much insulation. So, maybe the newer ones have jitter removal tech which auto-correct 192kHz signals and confused our Devialet.
It's just my wild guess.
Something you should know about optical fibre cable; The narrower the cable, the easier it is to keep the light going straight through instead of bouncing from wall to wall (resulting in delays that can result in jitter / loss of signal)
Standard Toslink cable is 1mm thick (the fibre part) which is enormous for light (a bit like a 6 lane highway for a remote controlled toy car) For internet and telephone, the narrower they can make the cable, the more precise they can get the light through. Then there's also the option of deliberately bouncing the light at different angles so you can send different packages at the same time (in much the same way as antenna polarisation horizontally or vertically but much more precise and at more angles) As far as I know Toslink is a 'straight through' system.
So if your cable is thin that might well be the reason it is the only one that works. You might have a winner there. Keep it!
Have you tried 192kHz with 7.1.1? It can't be just the cable that made it work surely?
