So, I updated and my startech usb sound device (https://www.startech.com/en-us/cards-adapters/icusbaudio2d) doesn't work anymore. I plug it in, and the lights come on, and there's a hissing in the ear phones, and after a while they get hot. I never had hot ear phones before.
I don't see the device in pavucontrol or in the plasma system settings.
Attached is what alsamixer looks like.

I tried a similar more compact/defaultish config, but it didn't work.
