The amp was off . My apologies. This is what I'm getting now after test 1 :

pi@berryaudio:~$ sudo systemctl stop berryaudio.service
pi@berryaudio:~$ sudo systemctl stop camilladsp.service
pi@berryaudio:~$ aplay -D hw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params Sample format non available
Available formats:
- S32_LE
pi@berryaudio:~$


after test 2 :

pi@berryaudio:~$ sudo systemctl stop berryaudio.service
pi@berryaudio:~$ sudo systemctl stop camilladsp.service
pi@berryaudio:~$ aplay -D plughw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
pi@berryaudio:~$

test 2 played the wav file

The DAC is connected to the pi's usb port yes.

pi@berryaudio:~$ lsusb
Bus 001 Device 004: ID 22e8:dac4 Cambridge Audio Azur DacMagic 100
Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc. (formerly SMSC) SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Microchip Technology, Inc. (formerly SMSC) SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
pi@berryaudio:~$

now that wav file plays you should be able to play audio from berry audio after selecting Camebridge dacmagic100 plughw:CARD=C2,DEV=0 from the device selection dropdown in the Mixers settings

Make sure you restart berryaudio leave the DAC powered on and connected

Let me know how that goes

Still no joy. The plughw is not showing in the mixer dropdown so I changed hw into plughw in mixers.json.
The audiofile from test 2 stills play. It doesn't make sense. The dtoverlay in the mixers.json for the Cambridge dacmagic is empty though. Does that make a difference?

Cambridge audio is a usb DAC and dr overlay is not required - dt overlays are only for pi HAT based dacs to Load drivers

That's good to know. Have we got other options or is this the end of the road?

will probably check with some friends over the weekend if anyone has a USB DAC Amplifier and test out some configurations

Great. Looking forward to it.
