hi all
a quick note to confirm other people's experiences, based on udo's recipe, in case useful:
for me the Pi Zero WH - the version with pre soldered header and wifi - and the IQAudio codec zero https://shop.pimoroni.com/products/iqaudio-codec-zero work perfectly out of the box with the latest disk image from Stef @LS Dev This is the one called: unstable version 4.0-dev http://locusonus.org/streambox/
For me it is in fact stable with dns and wifi issues resolved and the sound is remarkable from this card with the PUI capsules: https://eu.mouser.com/datasheet/2/334/AOM-5024L-HD-R-1219369.pdf Sounds clean and good running with a mains adaptor or a battery
best wishes grant
