It was fate.

So I can only presume you didn't search these forums for SPDIF before you created this thread? Oh well! :/

I'm having issues with this.
I own a Juli@ XTe PCIe card, and I'm trying to use the S/PDIF in to record my guitar, which is connected to the S/PDIF in via its FX-unit. This all worked fine with a Lexicon Omega USB, as that did the mixing itself.

I just can't get it to work. I followed this guide, but I have no "PCM Input Source". Here's a couple of informational pictures from both JACK and QASMixer:

Here's my Cadence settings. I note that there's an additional entry for the hw:Juli,1 but that effectively doesn't work using, at least not by itself like that.

My alsamixer.

My QASMixer. Super-kudos to anyone that can explain to me what the different controls mean/do btw :D

I'm in desperate need of help here, I just simply _can't_ figure out how to do this. Thanks a ton in advance!

It's probably a good thing he didn't use that guide, because that's for a different kind of card that works strangely. Every single SPDIF IO I've ever enabled in linux (dozens and dozens) has not required your process; only to unmute the digital outs as explained in this thread.... Still, it's good that the two threads are linked now!
