Raspberry Pi 5, Raspberry Pi DAC+ not being detected by Volumio

Help and Support Help

Hello everyone! I’ve been trying to set up Volumio in my Raspberry Pi 5.

I plug the DAC in, it turns on (green light on), but when trying to select it in Volumio it doesn’t work!

I ran these commands in SSH:

aplay -l
i2cdetect -y 1

I don’t have the outputs right now, but aplay won’t show the DAC as an available output, only the HDMI outputs (hdmi0 and 1), i2cdetect -y 1 also won’t show anything (full of dashes)

What could be the problem? Is the DAC dead somehow?

Hi @MrCoolAndroid

Please provide more details.
We cannot see your setup, so guessing is not an option.

Right now, the only information we have is:

  • Raspberry Pi 5 (there are ~10 different RAM variants)
  • Some I²C DAC (there are 120+ different DAC HATs)

That already gives us ~1200 possible combinations.
Troubleshooting like this is impossible.

To continue, you must provide the following:

Required information

  • Exact Raspberry Pi model
    (e.g. Raspberry Pi 5 4GB, 8GB, 16GB — not just “RPI5”)
  • Exact DAC details
    • Brand
    • Model
    • Chipset (if known)
  • Exact Volumio version
    • Full version number
    • Do NOT say “latest” — we need the exact version string
  • Provide a log
    Without this information, nobody can help you effectively.

Once you provide the above, we can actually troubleshoot instead of guessing.

If your DAC is really a Raspberry Pi DAC+ as suggested in the title, then you choose it as IQaudIO Pi-DAC+ in the setup of Volumio (General Playback Options).
Save, Restart.
Once Volumio has restarted, once again select Menu/Playback options.
Ensure that the Volume Options have the Mixer type as Hardware, and that the Mixer Control Name is set to “Digital”.
Press Save.

The DAC+ is a HAT compliant add-on accessory for the Raspberry Pi A+/B+/RPi2/RPi3 or PRi4.
The DAC+ uses the Texas Instruments PCM5122 DAC to deliver analogue audio to the DAC+’s
Phono connectors. The PI-DAC+ also supports a dedicated headphone amplifier.

Sorry!

Here’s the info I have for now:

Raspberry Pi 5 4GB RAM

The DAC is the Raspberry Pi one, it’s called Raspberry Pi DAC+

Volumio version 4.119

Here’s the log: http://logs.volumio.org/volumio/12qioev.html

I’ll try this and let you know!

So, IQaudio Pi-Digi+ doesn’t work, shows undefined when trying to select Hardware, but this doesn’t happen when selecting Raspberry Pi DAC+ and IQaudio DAC Plus, I can select Hardware and Digital, but the audio doesn’t work regardless of the option

Looks like the DAC board is broken, it’s not being detected.

Dang, it stills shows a green light though, but yeah I guess the chip is dead or something, I bought another one hopefully everything will work

The new DAC arrived and it’s working now, thanks everyone for the help!
