Thanks for all the info!
As I can see the device fine, I'm assuming my DT is alright.
I think I'm going to try some other images (ie. debian, main kernel, etc...) and see where it leads me, maybe I can get a hint of what's happening.
I can change devices fine in KDE, the jack detect works as I see it toggle, but I don't get anything out. HDMI audio works fine though.
I've seen some weird audio stuff a long time ago, I'll see what little I can remember since it doesn't seem to be something blatantly obvious.
I have a hunch or two but unlikely to make any difference
Ubuntu making it worse doesn't sound good to me... hehehe (pun intended)
I'm planning to use it as a 2nd desktop/media player, most of the time I don't need the "power" of the "workstation" so running the opi works great (well, will hopefully)
I went with KDE since that's what I'm using on the "workstation".
To be honest, there's very high probabilities I'm going to buy a USB sound card and be done with it, but it feels like a waste.
