Sorry, but here's another pertinent factor that I should have mentioned earlier
if I haven't:
It could very well be a bug in the UA-101's firmware, since if I connect an
audible input and watch it on the UA-101's builtin levels meter (with it
already on), I think it does freeze. The levels remain when the input is
unplugged, after plugging in USB while running a nonworking commit.
Thanks for the insight!
I suppose I should start comparing the code to each module, since I think
that's what you're suggesting.
