Rossini Apex Toslink input not working

[Ermos (Erno)]

There was a firmware update that fixed the problem with SPDIF2 some time ago

Rossini Player & DAC – Software Update v2.02 / 506

1st October 2021

Fixed an issue where DSD files were being truncated upon starting playback.

TOSLINK input no longer causes “NON-AUDIO” to be shown on the unit display.

I had not tried the Toslink input since the DAC came back from the APEX upgrade, so maybe this got damaged during the upgrade?

SPDIF is handled by the StreamUnlimited interface board, that is not part of the APEX upgrade, so it is not likely that an APEX upgrade caused your Toslink problem.

Myself I am having another strange problem with SPDIF3 on my Rossine Apex DAC. Although Toslink is not connected, and never was, I cannot skip it when cycling through the Input Menu:

DCS OEM Remote control

To describe what is happening: I am on USB1 and want to switch to Network. I press the DAC in button on the dCS remote, it then jumps to SPDIF3 (not even connected), press again it goes back to USB1, then again SPDIF3, USB1 etc. and eventually it gets to Network after 3 - 5 cycles.
