I was trying to take an audio output from piZero-W, the article I followed was, this one.

How to get audio through the gpio pins to a 3.5mm jack?

When running - systemctl status alsa-state

the result is

alsa-state.service - Manage Sound Card State (restore and store)
   Loaded: loaded (/lib/systemd/system/alsa-state.service; static; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:alsactl(1)

Firstly you need to build the circuit described in the adafruit article that you linked. https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero/overview

Here is mine, connected to GND, GPIO12 and GPIO13:

enter image description here

Then in the /boot/config.txt file you need to add an overlay entry to remap the audio:

dtoverlay=audremap,pins_12_13

Then in 'sudo raspi-config' configure the audio to Headphones.

Test with:

speaker-test -c2

Should hear noise from left and right channels.
