I need to get SPDIF working with ARDOUR. It is not really an Ardour problem, more of a system problem. I had spdif issues with several audio interfaces, so it is not the interfaces. SPDIF would work once but then never again.
It is clear to me it is ALSA at fault. The ALSA usergroup is basically dead and there are no responses. So i have to ask here.
Maybe someone here is an spdif boffin. I just cannot continue with audio cables to my keyboards anymore. Too many cables and screening issues. My Yamaha keyboards leaks some MIDI clock signal noise into the audio cables and I have to wiggle them a bit to get rid of the clicks. Once I use SPDIF, all this crap is gone + all the cables are unnecessary.
SPDIF, when it works is magic.
I run keyboards with spdif to a Behringer 1820 & Presonus 1818VSL into Linux with Alsa/Jack/Ardour & Mixbus.
Never mind how I set the clocks I get no spdif. signal.
It worked once but then gave up again.
No clue anymore.
Tested interface on windows and it works perfectly.
Everything else works spectacular on Linux except spdif.

If you feel this is rather a question for Linux Audio group and you are a moderator let me know as it is highly unlikely to be Ardour, but it might be…
