Hi Raphael,

You're right, the distrib. should natively supports USB audio class (2.0 for the Sonosax).

The system on the streambox is strictly the minimum, maybe something is missing, but can't find what without a similar device.

The one coming with the version 3.1 have one or two years now, maybe try with a newer kernel/system, i.e. the unstable version 4.0.

note, some USB audio hardware is known not to work properly when plugged into USB 3 ports so try USB 2/1 ports instead (in case)

best,

Hi,
I'm installing a RPi 4 with latest Streambox distribution (3.1 stable from locusonus website). All installed successfully, I can access with streambox.local or SSH, but my soundcard is not recognized. It's a Sonosax M2D2 preamp, self-powered, class compliant, which works OOTB on all my Linux systems.
I don't see it in "list audio devices":
0 [ALSA           ]: bcm2835_alsa - bcm2835 ALSA
                      bcm2835 ALSA


Thank you for your help...
