I've installed the respeaker pi hat module to my Rpi0W using 

sudo apt-get update
sudo apt-get upgrade
git clone https://github.com/respeaker/seeed-voicecard.git
cd seeed-voicecard
sudo ./install.sh
reboot

but cannot test whether it works - The tutorial states I can pipe the recording and play it as such 

arecord -f cd -Dhw:1 | aplay -Dhw:1

but this is not working? I guess my hardware is listed differently? but i can't figure out how i should make the same call above with my hardware list?

pi@raspberrypi:~ $ aplay -l && arecord -l

I would first verify that you are running the appropriate operating system,

Make sure that you are running the lastest Raspbian Operating System(debian 9) on your Pi. (updated at 2018.11.13)

I would also validate that the volume is set at the correct level, and that you have a speaker or earphones plugged in,

Test, you will hear what you say to the microphones(don't forget to plug in an earphone or a speaker)

The volume can be set using alsamixer from the terminal.

as far as i know the syntax, it looks like you arn't calling the device properly. it should be something like this:

-D hw:1,0

as satated here under "The naming of PCM devices"
