Hi folks,

I just received my Raspi Zero W and the pHAT DAC, installed Raspbian Stretch Lite, changed the sudo user to a different name than pi and followed the tutorial to install the dac libraries (

However, when I run
curl | bash
for a second time, I’m getting the following error when testing the speaker:

speaker-test 1.1.3

boot/config.txt looks good to me. Does anyone have an idea what could have went wrong?

Many thanks in advance for your support :-)

What do you see when you run:

aplay -L


aplay -l

aplay -L
Discard all samples (playback) or generate zero samples (capture)

aplay -l
aplay: device_list:270: no soundcards found...

soldering is fine and the board is connected the right way. maybe it’s broken?

or is this an issue with debian 9 (stretch)?

Sorry for the late reply- did you have any luck?

Audio-out should work even if the board isn’t connected at all, since it just wiggles some pins in the right way and has no idea a DAC is connected, so this must be a software issue.

Seems audio isn’t enabled at all in your case- what was in /boot/config.txt?

I’ve switched back to debian 8 (jessie), did the same installation again and it works perfectly.
