Hi, Jeanette! It's been a while since I had my Delta 1010s, but lets see what I can remember. The network amd Braille reader issue reminded me of an issue I had ages ago with my 1010s and a USB MIDI control surface. I documented my fix at https://delta.brainiac.com/deltasync.html In short, I had to modify the modprobe.conf file to make device labeling consistent, then I built an .asoundrc file that combined the cards into a single device. This was a long time ago, and I was using Fedora back then. I know that modprobe.conf lives in /etc/modprobe.d/ under Arch but I think that's the only big difference between what's on my website and Arch. Good luck!
