pHat Dac Pi Zero,No audio

Installed the Dac onto the Pi Zero using this guide and I am not getting any sound through the speaker. I am using volumio and Hifiberry Dac does show up in my list as the output device. Any ideas?

I decided to hook up some earbuds just to see what would happen and I got sound. Hmmm.
I ws trying to use this Speaker.
Any reason it shouldn’t work?
