some more info:
Perhaps it is a jack problem. Using OSS and testing with pd there is
full duplex in the H4n with the following:
pd -audioindev 2 -audiooutdev 2 -verbose -r 48000
although there is an error message printed in pd:
iain@nonix:~$ pd -audioindev 2 -audiooutdev 2 -verbose -r 48000 -stderr
&
[1] 8076
iain@nonix:~$ Pd version 0.42-5

Anyway - it's promising that it works in duplex

Hello Iain!
Only one small thought. when you use the Zoom as a standalone, there seems
to be a blockage, when recording and uing the speaker for playback. Have you
tried plugging in headphones while using the h4n in full duplex? Othen than
that, No ideas. I have one for the moment, but I only used it once for full
duplex and I remember we did a bit of trickery, but that may have been due to
the fact, that we had no JACK.
Warm regards
Julien
