Hi Justin,
I have a Zoom H4 and had similar ideas of using it as a laptop audio
device, but the mics are indeed always monitoring and I never found
any way of turning this off.

The mixing I need is controlling the monitor level of
the mic. It
seems to be always on if the mic is on at all. Actually it may not be
a separate control on this chip. I guess I could expect as much from a
$200 sound card / flash card reader / 4 channel flash card surround
recorder / mp3 player / tuner / metronome / toaster (guess which it
does not actually do).
I cannot seem to find the chip documented anywhere, but I do know that
it uses the standard snd_usb_audio module.
It seems like my best workaround is to use the h2 only as an input,
except its output is a bit better than my built in sound card and I
need about 16 times the latency and still get xruns every couple of
seconds if I use the separate devices for input/output.

To celebrate my new full time job, and payday, I
just got a zoom h2.
It records four channels from its four microphones, runs on AA
batteries, and can be accessed as a hard drive or a sound card (sadly
only two mics at a time when a sound card). Excellent little machine
for the price.
My one problem is that alsa (either via amixer, alsamixer or
oss-emulation mixer via aumix) will not give me any mixer controls. Am
I stuck with using the silly buttons on the machine for all mixing,
when I use it as a sound card? How hard would it be to write a mixer
for it... is the problem a lack of developer time or an issue with the
device itself?
What kind of mixing controls do you need? If it's just simple stuff for
playback/working with alsa, it might be possible to use another layer,
like pulseaudio.
For jack, I think there is a pretty sophisticated mixer available. I
never used it myself, I think it is called jackmixer or something.
I don't know what kind of chip it uses, maybe you can use a mixer app
for other soundcards? (Envy24 control, ...)
Best Regards,
Philipp
