Now, I want to plug in a usb microphone in

device already running. So, the question becomes: How do I add a 2nd
device to an already running jackd? Or do I need to tell jack when it
starts to use 2 devices (again, how?). And, will audacity catch on to
this?
In this case I would probably start jack using the USB audio interface
and use alsa_in for the microphone.
FWIW, I tried alsa_out once upon a time, to handle a 4-channel-out USB interface
that appears to Linux as two stereo devices. It was a complete disaster. After
booting Jack and launching alsa_out, it took between 5 and 10 minutes before the
devices would synchronize. Before that, constant glitching. Then, if I left the
devices silent for a time, they would go out of sync again after a few minutes.
More glitching.
At that point, I started to feel that was no longer a viable solution to
explore. I (still) wouldn't trust alsa_out or _in for anything serious.
YMMV.
