No sound from DAC+

I managed to set up Balena Sound according to your tutorial, thanks. I’m connecting via Bluetooth. There is sound when I use the Raspberry standard output (3.5mm audio cable), but there is no sound when I use the HifiBerry.

I’m using a Raspberry Pi3 B with HifiBerry DAC+ HW2.3.

The device configuration is set according to the tutorial
RESIN_HOST_CONFIG_dtparam “i2c_arm=on”,“spi=on”,“audio=off”
BALENA_HOST_CONFIG_dtoverlay hifiberry-dac

The log reports

Please help.

Is the sound clean when using rpi standard output? I’m asking because error logs look like similar to: balenaSound blueooth audio on Raspberry Pi 3: Sound skipping, dropping . Also, can you grant support access and provide device url so that we can take a closer look?

Thanks for the fast rewply. What do mean with ‘clean’? The sound is ok (as expected) when I use the RPi standard output – it’s not HiFi and sometimes there is a small gap. But this is not my issue.

My issue is that there is no sound at all when I use the HifiBerry.

Are there other parameters beside the ones in the tutorial (see above) that need to be set for a HifiBerry DAC+ HW2.3?
Are there other pararmeters or settings that provide more information about what’s wrong (e.g. in the log)?

Hi ,
the balena sound maintainer has just taken a look at this and he thinks you might be using the wrong overlay.
According to he thinks you will need to use hifiberry-dacplus overlay rather than hifiberry-dac.
It could also be helpful to identify the exact hifiberry ( see ) version you are using as the required overlays might differ further.

Great, after setting BALENA_HOST_CONFIG_dtoverlay to hifiberry-dacplus it is working. My issue is solved.
The sound is moch better using the RPi standard output.
Thanks a lot for your quick help.

Glad to read that! Happy hacking!

I seem to have the same problem with my DAC+ (
Here is what I configured:

RPi 3B+
balenaOS 2.58.3+rev1
Define DT parameters “i2c_arm=on”,“spi=on”,“audio=off”
BALENA_HOST_CONFIG_dtoverlay hifiberry-dacplus

Still I got no sound, has anybody got an idea what else I could try?
Ah and sound works using standard-output.

Thanks in advance!

A little update from me, I just installed HifiBerryOS to check, whether my DAC might have a hardware problem.
With HifiBerryOS the RPI with DAC works flawlessly out of the box, so there must be something wrong with my setup in BalenaOS.

I also tested with my DAC+ Zero with BalenaOS, changed “BALENA_HOST_CONFIG_dtoverlay” to “hifiberry-dac” which works perfectly.

Here is what I do to install:

  • Download OS for RPI
  • Boot RPI up
  • Change Define DT parameters “i2c_arm=on”,“spi=on”,“audio=on” to Define DT parameters “i2c_arm=on”,“spi=on”,“audio=off”
  • Add BALENA_HOST_CONFIG_dtoverlay hifiberry-dacplus
  • Disconnect power
  • Boot

Is there something wrong with my way here?

Hi there,
I’d like to ask you how you download the BalenaOS and flash the image? We now have the “Deploy with balena” option you can find here: that allows you to deploy balenaSound project directly to a balenaCloud application.
Notice that we’ve also released recently the balenaSound v3, which resolves many issues we’ve had in the past.

Hello georgiats,

thank you very much for your reply! I deployed the project, which resulted in updates of my RPIs and voilá the dac+ works!!
Before I downloaded the versions by adding a new device, but it seems this didn’t result in the newest versions.

Thanks again for this advice, it helped me a lot!
