First tried 1.0.x and 1.1.x but was unable to get to the web interface when using either one. The IP changed, of course, but even after retrieving the correct value from my router I still could not see the server. Weird. So I headed back to try 1.2.0. I did not use the upgrade to 1.2.1 so as to eliminate any variables there. At this point the server showed the previous usb errors, but the snakeoil logs showed something far better:

This is positive.
A few issues still persist:
- The DAC still displays 'no lock' status.
- Mytek does not appear as an ALSA Output Device (should it??? I'm guessing yes)
- myMPD displays MPD disconnected for some reason (I'll look into this next)
EDIT: Ran the loader:
./mytekusb2-firmware-loader.sh
Checking for ALSA Mytek device

Failed to insert module snd_usb_mytek
I'd be willing to drop this file in the right place myself, but imagine there might be some enumeration that goes along with it. Almost feels like a permissions thing. Will keep hacking.
