So, finished soldering my pimeroni pi zero and phat dac.
Tried the one line installer and get “-failed to connect to get.pimori.com port 443”
Followed the manual setup at https://learn.pimoroni.com/tutorial/phat/raspberry-pi-phat-dac-install
reboot to no sound. From desktop select audio device settings and get “No ALSA audi devices were detected”
Continuity checks on the soldering is fine on all pins, when powered AVO shows 5V between pins 2 & 39.
