Quantum 2626 SPDIF output issues

[Number6]

Hello

As per usual I'm getting output to the main outs to one of my amps, however I'm trying to get audio from the SPDIF (Coax) out to another amp, I'm just using Studio One for now as an Output and I'm not hearing anything:

Latest mix control version below in Windows 11, I've tried S/PDIF mirrors mains button on and off.
Still no signal coming out (although the screenshot below appears to say otherwise), any ideas?

Thanks

Just checking, but is the other amp in sync in WordClock and/or has it the same samplerate?

Also: how long is that S/PDIF cable? And is it a digital audio cable (75 Ohms)?

Don't need to be connected to a clock (?). I'm not ADAT'ing here for this.

My main outputs are connected to a couple of Yamaha HS7 monitors (active). Working.

The SPDIF is connecting to an Arcam A5+ with Wharfedale speakers. Not working (I've ruled out the amp itself being the issue).

I won't be listening to both at the same time.
Cable is less than half a meter and is decent (bought it specially)

BTW the "S/PDIF mirrors mains" button in that screenshot on my first post, it's completely unclear whether the button is in an on or off state, either way tested all combinations.

S/PDIF does support several different samplerates, that needs to be in synch on both ends. I don't think a clock is absolutely necessary, iirc a clock signal is included in the data stream, but not all receiving hardware knows how to read the time..

Apologies for wasting everybody's time. 2626 had always worked and the issue was at my end, I had a DAC converter that failed along the chain (long story but now resolved). Thanks...

BTW I've worked out that when the "S/PDIF mirrors mains" button is fully white, it is on. If Presonus (er sorry Fender) is watching the UI needs improving to clearly indicate this without confusion. A tick box would be far better, or even a pretend LED that lights up.

Glad you worked it out!
