justboom digi zero and Pi Zero W not working

Troubleshooting
1

Hi,

I’ve just started using Diet Pi and I’m trying to get version 7.2 working with my Justboom digi zero DAC.

I set the sound card to justboom-digi in the config and rebooted. However when I try to test it I get this:

dietpi@DietPi:~$ aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
dietpi@DietPi:~$ speaker-test

speaker-test 1.1.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Playback open error: -13,Permission denied
dietpi@DietPi:~$ sudo speaker-test

speaker-test 1.1.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Channels count (1) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument
dietpi@DietPi:~$

I installed Rasbian Jessie Lite and after an upgrade/dist-upgrade the DAC worked - so I think it is something in Diet Pi and not the card.

Is anyone able to help me?

You are the sound expert. Maybe you can have a look

Rasbian Jessie Lite

Where did you get a Raspbian Jessie image from? That should not be offered anywhere for years :wink:.

Please try to enable the automatic conversions plugin:

  • Run dietpi-config
  • Select Audio Options
  • Select Auto-conversion so that it states [On]

No reboot required, simply run again the speaker-test. To allow playing audio with the dietpi user (without sudo):

usermod -aG audio dietpi

Rasbian Jessie Lite

My hope is/was that this was a typo :wink:

Sorry yeah was raspios buster! I was trying so many images and tearing my hair out yesterday until I found it was the DAC wasn’t quite seated correctly!

So before the reply I installed snapclient and that was working.

After the instructinos above the speaker_test works as well.

Thanks for your help - as Joulinar has seen i’ve submitted a PR to get snapclient added to the software repo.
