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 the sdhost driver

# 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…
