No audio from Pirate Audio line out shim

Support
1

Hi all,
I’m trying to get this shim working.

Here is my boot config file

initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
#dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1

include userconfig.txt

#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dac

gpio=25=op,dh

dtparam=spi=on

I am using it with volumio, and the “hifiberry DAC” option appears as a selection in the “audio output” list. But no sound comes out

I have it in my devices - when I type aplay -l I get this

card 2: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

If I type

mplayer -ao alsa:device=hw=2,0 sin1000_48khz.wav

It says the sound is playing but I get no audio.

Any help appreciated!

Note that the shim is soldered and I’ve checked there are no accidental connections between the pins.
