Phat DAC no audio


#1

I’m trying to get pHAT DAC to work on a raspberry pi zero w. I soldered it and ran

 curl -sS https://get.pimoroni.com/phatdac | bash.

On 2nd run(test) there is no sound. I tried the manual install aswell but same result. What should I do?
Also no sound with

 speaker-test -c 2 -t wav

I had a phat dac where I can’t get any sound out of either. I was luckily able to exchange for another one and used the “lazy” method of soldering the new one and now the dac I have works great.

I hate to be the bearer of bad news, but you appear to have soldered the pHAT DAC to the Pi Zero upside-down.

Right-side top-wards it should look like this:
