No not quite the UA-20, and usb-audio in general, does work with alsa.
It's Jack and its alsa driver.

As far as I know 44.1 khz  is the standard for CD. After too much time
searching it's the reason I came up with.  Looking at jack-devel
archives it was a heated debate to have jack use anything that wasn't
n^2.  It looked like they decided to support it, but at least the
version of jack I have doesn't yet.

Once again though, I barely understand it myself. I looked for a link
that was straight forward in explaining it, but no luck.  Maybe someone
else here can explain it better.
