How to get started with AudioInjector Zero soundcard

So I've assembled my Audio Injector sound card, mounted it on my Raspberry Pi Zero W, installed .deb package and run installation .sh script. If I run aplay -l my Audio Injector is listed correctly. They ran OK without errors. What do I do now?

What I want to do as a test is take the audio input from the onboard electret microphone and then send it out the headphone jack. Once that works, I want to send the output from the microphone for playback on another computer over the LAN using JACK Audio.

I cannot get this to work currently. If I run speaker-test there is no output from the headphone jack and an input/output error occurs.

So please could someone tell me what the next steps of the setup procedure should be to do what I want?
