The audio server you are talking about is PulseAudio. and yes that is the 
way it works. solution:
pactl unload-module module-udev-detect
pactl unload-module module-alsa-card

Now use zita-ajbridge  to make your H2 recorder show or use jack_control 
set up the h2 as master device and then SM. Sometimes jack_control sm 
(switch master) works wonderfully time after time. Sometimes jack hangs at 
that point and needs killall -9 jackdbus and a jack_control start.
