Hi community,
I’ve been using volumio since years (with a Hifiberry DAC) and it is working very well.
Now I bought a Topping D50 iii DAC but did not check the compatibility careful enough
I saw some D50 models are listed so I thought my D50 iii will also work.
But now I see it is not working, at least not when I connect it via USB.
On a W11 laptop the DAC is working, but I had installed some Topping drivers before I have tested.
What can I do now?
Thanks in advance for any helping advise
My volumio runs on a Raspberry pi 3B.
Volumio is on Version 3.785.
The firmware of the DAC is version 1.39
Now I have updated to Volumio 3.785 - DAC still creates distorbed sound.
Behavior of the starting Volumio is different. When having the DAC disconnected it tells me “Wiedergabegerät erfolgreich gestartet” / “audio device started successfully” - with the older version there was a message telling audio device could not be started.

The snd-usb-audio kernel driver is pretty robust and mature. There is something odd in the USB firmware of the device itself. I would check with the manufacturer for similar reports or, perhaps, newer firmware.
Reading reviews I notice the the D50 III implements optional preamp and parametric EQ. You may need to disable those modes. Also if you have hardware volume control enabled in Volumio, try the SW volume control.
