yes, but you did not tell us what DAC you have (brand/model).
The log does not show any sign of a dac connected to any usb port.
Not even an error, which is strange.
Can you re-try without any other usb devices (like an external disk) connected, or try another cable and a different usb port?
Logs of each test welcome!

Hi, my dac I wrote in the 2nd line of the logs.
It is l.k.s 004 upgrade edition : l.k.s. audio mh-da004

Volumio sees nothing. Will install them again. DAC, cable is working, moodeaudio is playing.
In moodeaudio it is detected immediately. I plug it in, set the dac to Combo384 Amanero
moodeaudio shows:

I installed the last volumio now, it’s the same. I just changed the software from moode to volumio.

Could you do an “lsmod” to see which modules have been loaded?
It should show snd-usb-audio, but I guess it does not.

Did you enable usb on the cm4io by adding

dtoverlay=dwc2,dr_mode=host

to your config.txt?

Thank you, it works :slight_smile:
The usb dac should be detected right away, it’s strange that the volumio does not add it right away.
Can you post a link to these commands?

These are things you should know when you use a cm4io board, it is in the manual. USB ports are disabled by default, it is cm4io-specific.
