I’m trying to get [pHAT DAC](https://shop.pimoroni.com/products/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

pi@raspberrypi:~ $ aplay -l

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.

For simplicity (or added strength), sometimes I included some pins unnecessary for functionality. a basic rule of thumb, if you’re not sure what is needed, is to solder 6 pins (2x3) at both ends, then check [http://pinout.xyz](http://pinout.xyz) for any additional pins needed for operation. It’s sometimes possible to tell what pins are in use by examining the circuit board (on both sides!), and if you’d …

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:
