Hi.
I’m testing Balena Sound, after following the manual (thanks really useful) there is no sound in the DAC 3.5mm, the current settings are:
BALENA_HOST_CONFIG_dtoverlay not defined hifiberry-dac
Define DT parameters not defined “i2c_arm=on”,“spi=on”,“audio=off”
How could I check if the DAC Hat is working ok?
Hey @Wontolla welcome to the forums. You can check to see if things are working correctly by opening a terminal to the audio service and running aplay -L. This will list all the devices found by the system. Could you do this and share the output?
Hi @Wontolla,
I have a RPi Zero W with a Pimoroni DAC, and I had to add the following environment variable for it to work. This is in addition to the dtoverlay variable you set above, but on the Environment Variables page.
SOUND_DEVICE = DAC
Also, this device config on mine looks different from yours:
Define DT parameters not defined “i2c_arm=on”,“spi=on”,“audio=on”
Try changing the audio part to “audio=on”
Hope that helps.
Cheers!

I’m also, testing koyaanisqatsi config.
Thank you.
No luck I’ve added the variables:
SOUND_DEVICE not defined DAC
Define DT parameters not defined “i2c_arm=on”,“spi=on”,“audio=on”
Custom Variable
BALENA_HOST_CONFIG_dtoverlay not defined hifiberry-dac
Hey Galvar, there’s a slight chance the dt_param was not successfully set for whatever reason so a quick test is to try power cycling the device as well and see if it’s resolved. I don’t think that will solve it but worth a shot for now until we provide more steps.
Hi, thanx, still no luck.
I’ve check that aplay -L showed a device:
snd_rpi_hifiberry_dac and I’ve set the CUSTOM CONFIGURATION VARIABLES
to:
BALENA_HOST_CONFIG_dtoverlay not defined snd_rpi_hifiberry_dac
But now, after several reboots:
/usr/src# aplay -L

Could not find the DAC, the Pimoroni is not soldered it 's connected by a plastic piece with pins so I’m kinda lost here, because several other times the DAC was listed.
Hi.
After setting again the
CUSTOM CONFIGURATION VARIABLES
BALENA_HOST_CONFIG_dtoverlay not defined hifiberry-dac
aplay -L lists again:

But still no audio.
Just an idea:
cat /proc/asound/modules
0 snd_bcm2835
1 snd_soc_rpi_simple_soundcard
Is that the sound cards order?.
Hi there, looks like the audio hardware is being detected. Can you try setting AUDIO_OUTPUT env var to DAC as per the notes on the audio block.
