No DAC in Audio Output Device menu

Hi all.
So, I've got the PMS running on Linux Mint in the living room, and in the family room I've got a Pi Zero W with a JustBoom DAC and Rasplex on it. I've been able to get Rasplex to see my music library in Mint, and when the Pi is connected via HDMI, I can get audio output from it. But what I'd like to do is have the Pi running headlessly in the family room, and output via the JustBoom DAC so I can run the audio through my amp. The problem is, I don't see the JustBoom DAC as an option under Audio Output Device, so I get no sound. The amp I'd like to use is old, so using HDMI on it isn't an option.

Here's part of my config.txt:

################################################################################
#
# >>>>>>>> RasPlex default settings override <<<<<<<<<

################################################################################

# Required overlay for LIRC to function
#  dtoverlay=lirc-rpi

# Required for hyperion / lightberry

# Uncomment to enable HiFiBerry overlay
# NOTE: You must disable the lirc-rpi overlay (or change lirc GPIO pin) for HiFiBerry to work correctly
# dtoverlay=hifiberry-amp
# dtoverlay=hifiberry-dac
# dtoverlay=hifiberry-dacplus
# dtoverlay=hifiberry-digi
  dtoverlay=justboom-dac

################################################################################
# End of default configuration

Thanks for your help.

    HI,

    I'm kind of in the same place as you... but Not ready to test yet.....

    I don't know if this will work on this distribution ... you may have to ensure the modules are available on the base OS, but this is how I configured Volumio to re divert the sound output via I2s. (I have a homemade non oversampling DAC attached).

    • Use pico/nano  to edit the /etc/modules file
        ○ pico /etc/modules
        ○ Pico is WYSIWYG
        ○ Delete the contents 
        ○ Replace with this
    
        snd_soc_bcm2708
        snd_soc_bcm2708_i2s
        bcm2708_dmaengine
        snd-soc-pcm1794a
        snd_soc_rpi_dac
    
        ○ Save the file ctrl o
    • Reboot the pi
               Type reboot at # prompt!
    

    This is straight cut from my notes... I suggest you backup the current Modules file beforehand...

    let us know how you get on..
