Hi David, all,
Creating a new thread as the old one was pretty long...

This is what I got by connecting jack_delay to one output and putting
the headphone right in front of the microphones (connected only one to
the jack_delay input). These are common jack settings I use or have
used with this device, although the 32 Frames is very unstable and the
64 Frames one gets a few xruns depending on what it's used with (but
still more usable). The 128 Frames settings is very stable.

Ok, that's not really brilliant. When latency is already a problem,
this would end up contributing to it more than most soundcards.

- Zoom H5
shows 4 inputs in jack: the L/R mics and the inputs 1 and 2
Oh, can you just put the headphones right next to the mics (makes
astonishingly little difference in comparison to direct connections) and
use jack_iodelay for measuring out the latency of the H5 with your
settings?
Numbers are surprisingly hard to come by for any audio interface.
