Raspberry pi zero phat dac

I was initially getting the same problem as reported by hept (my kit was a pHAT DAC - Wireless Audio Kit straight from pimoroni).
Booting up on Raspbian lite. Instructions followed from http://learn.pimoroni.com/tutorial/phat/raspberry-pi-phat-dac-install
But no sound at all.
Reflashed the uSD and this time used the one-line installer + reboot. Still no sound.

Finally, I went through all the files that are supposed to be modified by the one liner and noticed some difference on /etc/asound.conf
I had some strange character between the "!" and the "default". I removed that and also I splat the "type hw card 0" on two lines. Reboot and voila.

So if this can help someone else.

pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
