Lost sound from Volumio running on Raspberry Pi 4

Help and Support
1

About two weeks ago, I could not get any sound from my Volumio on the Raspberry Pi. I can select the song and play it but I do not get any audio from my Azur 340R via the Cambridge Audio DAC Magic 100.

I am using the free version and have checked and changed the settings.
All the other settings were left unchanged when I installed it.
Have I missed something obvious?

Below are the settings of my configuration.
I only amended the Network Drive and the Wireless settings.

Hi Grzegorz,

I have changed the settings as per your email and there is still no sound output.

Thanks

Do you see your DAC on the list?
Is it connected via USB?

5

Yes, the DAC is on the device list and is connected by USB C.

I borrowed a USB DAC from a friend. So set up, it sounds very nicely. I don’t know what’s going on with you? Maybe change the USB cable …

HAd the same thing going on with the Allo-digione.
All seems to work, but no sound output.
Even after removing the overlay from the config.xt, Volumio still was under the impression that the allo was configured.
Finally I did a reinstall and it worked.

Changing the cable did not work.

Reinstall

Check this first, from the manual:

If your DacMagic 100 was manufactured prior to 2014, you will require an update to enable USB Audio 2.0 compatibility.

You can tell when your DacMagic was manufactured via the serial number. The numbers in bold below indicate the year followed by the month. In this example, the unit would have been made in August 2013.

XX C10501 1308 0001

11

Yes, that is the next step.

12

Thank you. Will do that before the reinstall.

From your screen shots I see it seems to say “Cambridge Audio DAC100 USB1”.
So when your DAC was produced after 2014, you still need to tell it to use USB Class 2.
Refer to the manual: https://techsupport.cambridgeaudio.com/hc/en-us/articles/4421557642641-How-do-I-use-my-DacMagic-100-in-USB-Audio-Class-2-0-mode-

If that does not work, well then I’m out of ideas. Cambridge DACs are a bit special with linux as they will not officially support it, but in the end they always do the basic work, which is producing good sound.

Thank you. Lots of leads for me to check out.

Nothing wrong with the Cambridge DacMagic 100 as it works perfectly.
I just rebuild Volumio. The music sounds great.
And I made a BACKUP copy of Volumio.

Thank you everyone for all the tips and advice.
