Thanks Peter for your thoughts. I'll do my best to answer your thoughts.

On my system (see specs below), using the US 4K Mini as system input and output (analog audio output, HDMI output, no input), and using either the editor keyboard or an Apple bluetooth extended keyboard, the L key will initiate playback but the J and K key will not work. I am using the standard keyboard layout with the only modification to it being the tab key changed to create node names in the color page. Additionally at this stage there is also no audio scrubbing, either using the editor board jog wheel, or just manually scrubbing back and forth.
If I change the I/O on system audio to my MixPre 6II then this issue is resolved. At the stage I am using the MIxPre for audio and the US 4K Mini for video output.
However once in this configuration another issue appeared. While the JKL and audio scrubbing was solved, during playback the audio waveform sped up and slowed down visually during playback. The playhead would not match up with the actual audio playing out. Honestly there was no way to edit points because the playhead was never where it was supposed to me. Reynaud was a huge help in helping me troubleshoot this and the answer to fixing this issue was to totally unplug the US 4K Mini. As soon as I did that the waveform stopped it's behavior and the playhead stayed spot on the waveform, like it was supposed to.
Of course I now have no output to a monitor and cannot even have the US 4K mini plugged into the system when I go to the Fairlight page.
One last system thought. My system is partitioned into two operating systems. The main one listed below is a clean install and basically only has Resolve on it, and a few plug-ins. No other non-system software. The other partition has the latest version of Catalina, with an up-to-date Resolve install as well as Adobe products and everything else I use. I get these exact same issues with both sets of operating systems.

We had some updates to the preferences settings in v17 and have the next phase in dev now. This will inc better separation of audio and video I/O selection which we think will assist with a lot of the I/O issues.
I look forward to testing out any changes when this is released. I do not know what "Support for the SE and DREK in jog" means however.

I have done a lot of thinking about what I mean when I say "modern" interface. I think it comes down to a few things, one of them being a more rack mounted solution so I am not tied to PCI cards. I admit that I do not know a lot about the Fairlight interfaces however my impression is that because Blackmagic has come out with a new USB controller, they are also designing a new audio interface...something much like the new Pro Tools Carbon. Because I am working on building a system that will last 3-5 years the concern I have is buying an interface that will get left behind during that time. I have some more research and education for myself to do in this area however.

For me my ingestion has has only occurred via sound files that are timecode locked. I have never ingested anything via the US 4K Mini until I started the Fairlight training from Ripple Training. During this period I have been using Fairlight, I was only looking to have audio/video output through the US 4K Mini. I can also say that in the edit page none of these issues have occurred.
One last thing concerning the US 4K Mini. Over the last 24 hours I have been using the US 4K Mini in Pro Tools as my audio/video playback device. So far I have not experienced any of these issues in the latest version of Pro Tools. I say this because I think it supports the thought that the US 4K Mini is not defective. I'll also say that I am brand new to Pro Tools so I have not stressed the system at all. But playback of both audio and video is working fine.
Again Peter, thanks for commenting. I hope my thoughts were helpful and I am happy to test anything if it helps the developers.
