@artsun So glad you're on your way to a solution.

It's all fixed. It turns out that I manually blacklisted snd-usb-audio some time ago for a specific tweak and forgot to unblacklist it. The worst thing being that what I was trying to do didn't work at all.

Learn by doing, they say. I would add "and forget along the way"

Thanks again to everyone for your comprehensive and spot on support!
