As it doesn't work on either Lampizator or Devialet it can be a faulty cable or the Innous failing. I know the AES/EBU input of the Devialet (from owning a 250) is fairly tolerant so even a modestly off-spec cable would "work". I'd check if the cable is correctly wired i.e. pin 1 to 1, 2 to 2 and 3 to 3. pin 1 is ground. If this is correct the Innous may have some fault. Is there a SPDIF coax output on the Innous? Try it....
