The current situation is however that kmix won't allow me to choose the rubix usb audio (because it isn't listed there). Mixxx on the other hand DOES use the rubix usb card/box, just like alsamixer is able to see the rubix while kmix does not.
Can you answer two questions
- is the USB snd card plugged in when you boot into TDE? (and windows or
whatever other system was not hibernated)
The usb sound card (roland rubix) is always plugged in. I reserve 1 pc for my weekly radio stream using mixxx, although any linux pc with mixxx installed can take over in case of trouble (which has never happened in 5 years) thanks to the universal nfs paths to my music library.
I never use sleep or hibernate (on linux), I only use the screensaver and the blankscreen that comes after it, just like I did 20 years ago. And windows is never left running as it requires a reboot to start linux via grub.
It might be that your soundcard comes up after kmix is started. As kmix does not update its list of soundcards you wnd up with a list withoute the "late" soundcards. So, could you restart kmix after you have confirmed that alsamixer sees the card? If the kmix then sees the card you'd need just a little udev hacking, if not ...

- What is the content of /dev/snd/
for example here it is
# find /dev/snd/ /dev/snd/ /dev/snd/by-id /dev/snd/by-id/usb-Philips_CE_Philips_SPC_1000NC_Webcam-02 /dev/snd/by-path /dev/snd/by-path/pci-0000:00:1a.0-usb-0:1.5:1.2 /dev/snd/by-path/pci-0000:00:1b.0 /dev/snd/controlC1 /dev/snd/pcmC1D0c /dev/snd/controlC0 /dev/snd/hwC0D3 /dev/snd/hwC0D2 /dev/snd/pcmC0D8p /dev/snd/pcmC0D7p /dev/snd/pcmC0D3p /dev/snd/pcmC0D2c /dev/snd/pcmC0D0c /dev/snd/pcmC0D0p /dev/snd/seq /dev/snd/timer
Here's mine:
find /dev/snd
/dev/snd /dev/snd/by-path /dev/snd/by-path/pci-0000:00:1b.0 /dev/snd/by-path/pci-0000:01:00.1 /dev/snd/by-path/pci-0000:00:1a.0-usb-0:1.5:1.0 /dev/snd/by-id /dev/snd/by-id/usb-Roland_Rubix24-00 /dev/snd/controlC1 /dev/snd/hwC1D0 /dev/snd/pcmC1D2c /dev/snd/pcmC1D0c /dev/snd/pcmC1D0p /dev/snd/controlC2 /dev/snd/hwC2D0 /dev/snd/pcmC2D9p /dev/snd/pcmC2D8p /dev/snd/pcmC2D7p /dev/snd/pcmC2D3p /dev/snd/controlC0 /dev/snd/midiC0D0 /dev/snd/pcmC0D0c /dev/snd/pcmC0D0p /dev/snd/seq /dev/snd/timer
This looks ok to me but maybe I'm missing something?
