Thanks for posting this - I have had a Pi3B running with the Cirius board for several years (maybe 4 or 5 now), but I am moving it into a solar charged enclosure so I can move it away from the power source and make it more autonomous. I have used Pi Zeros for other installation applications but was not thinking about it in this application - however due to the reduced power consumption it would make sense for me to change me entire setup to a PiZero with the IOAudio board and so I am wondering if you have any details on how you got the PiZero working for Locusonus stream
as said, I don't have Pi zero experience yet. What you've listend to is
a Pi3 + the IQAUdio Zero board: http://iqaudio.co.uk/hats/101-pi-codeczero.html
this board is for the pi zero, but obviously works nicely with a Pi3
I don't have a Pi Zero yet, but will so soon, then I can test how this
performs.
great news is that there is an audio board with stereo mic-in /w PIP,
working with a Pi3, Pi4 and hopefully Pi Zero.
Setup on the actual Pi3 is simple, the board is recognized by the
kernel (Raspbian GNU/Linux 10, Linux raspi3 4.19.97-v7+) without any
driver install needed.
the card is visible by the alsa:
pi@raspi3:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: IQaudIOCODEC [IQaudIOCODEC], device 0: IQaudIO CODEC HiFi v1.2 da7213-hifi-0 [IQaudIO CODEC HiFi v1.2 da7213-hifi-0]
Subdevices: 0/1
Subdevice #0: subdevice #0
So in a darkice config you can use it like:
...
device = hw:IQaudIOCODEC
sampleRate = 44100
bitsPerSample = 16
channel = 2
...
as soon as I have a pi zero I'll try the board and will report.

ps. The stream seems quite low gain here in the USAOn Apr 21, 2020, at 08:56, udo noll <un@aporee.org> wrote:
hi Grant & all locustreamers,
maybe I missed that info, but the IOAudio website says about the
pi-codecZero board (for the raspberry pi zero) that it is mono and
doesn't work with a pi3 etc., and didn't he mention that it doesn't
have PIP / bias voltage available?
anyway, it obviously works great with a stereo pair of Primo EM172.
that means this board together with pi zero would be perfectly small,
stereo and has low energy consumption. I'give it a try with a pi zero
soon.
I'm just listening now, it's quite low noise, better sounding than the
cirrus board. quite cool.
check our my backyard within the next hour:
