You don't need an RT-kernel for this. Most of the RT-patches are in
the standard kernel since a long time so this should work for you. And
jack _really_ needs to be able to lock down memory.

As mentioned by Jeremy, this is for USB - not built ins, but since you
have an USB device you should try it.

You're introducing additional complexity to the setup. You also seem
to be running them at different bit depth (24 vs 32) which may or may
not be a problem. Until you get things working, see if you can use the
ualex for playback as well.
