Solved: Front input signal processed by Kemper when input source is set to SPDIF Input Reamp - Public Beta 8.5.2.29290B

If my Kemper Input source is set to SPDIF Input Reamp and a guitar is plugged into the the Front Input, should I hear my plugged in guitar through the Kemper Headphone output?

By mistake, I upgraded to PROFILER Public Beta Operating System 8.5.2.29290B. I wasn't paying attention to my update prompts.

I haven't re-amped for a while. But I wrote down my procedure and I/O settings for my DAW, interface and on the Profiler and I've successfully re-amped with these settings quite a number of times.

Today when I switched to Input source as SPDIF Input Reamp, the only signal that gets processed by the Kemper is the Front Input. In the past, I don't believe this was ever the case.

My DAW is sending a mono signal on a SPDIF channel (according to the channel meters in the DAW) but I'm getting no re-amped signal at the Kemper headphone outputs out or from the Kemper SPDIF outputs.

My SPDIF output is set to Master Stereo.

Does this sound like something broke in the Beta release?

I found that I had a bad SPDIF cable connection.

Odd thing is, once I replaced the cable, the front input guitar signal stopped being processed by the Kemper.
