    Thanks for your advice, Paul - again, I don't understand (!) "Test using a full featured OS" - do you have a suggestion of an OS I should try?
    P.S. My DAC has always worked with my original SB Touch (over a decade old) - no driver issues there, so not sure why that would be an issue here....? (But what do I know! )

        Just quickly: whilst here, pull the usb cable out from the Dac, wait 30 secs or so, then plugg it back in.

        Wait again for 30 secs or so the type lsmod again

        Does the output change ?

        Is it a usb 2 certified cable.

        I know that sometimes drivers are dropped from the kernel, but not often.

        Try this desktop first

        U
        se rpi imager tool to make the image, one can preconfigure the imaage partially.

        There are guides on the rpi forum

          Have done that. The result is different, but still no 'snd_usb_audio' - see below. Yes, using certified USB cable produced by audio company.

              Raspberry pi has a long, not so good, history with regards to USB devices. But the pi4 mostly fixed those problems.....mostly. Up until the pi4, a USB dac simply was never recommended on a RPi device.
