I have just received and followed installation procedures and still can’t get sound. I am running updated and upgraded jessie lite.

Here is a picture of the soldering:

Hi there Abovedmc,  
What are you using to test that you’re getting an audio output? Make sure you’re not using omxplayer, since it doesn’t support alsa, which is used to output to the pHat DAC.

I am using speaker-test -c2 wav, connected to a powered speakers known to  
work.

Thanks for your prompt response. I have spent hours trying to get output.

Update on my problem described above. I removed the pHat DAC from Rpi Zero and attached it to my Rpi 3, Running Musicbox on raspbian which was outputting to USB dac, I modified /boot/config.txt by uncommenting dtoverlay=hifiberry-dac  
I modified /home/mopidy/mopidy.conf Audio Settings by commenting out downsample\_usb\_usb = true  
in same area I changed output+ " " to output = "hifiberry-dac"  
and scan\_always = True.

Was then able to use speaker-test successfully.

Only problem was that after these changes to Musicbox I can no longer login.
