I’m setting up a Raspberry Pi 4 8GB for connecting to Rotel RA-1572, yet the USB-DAC is not recognized.
I’ve looked at lsusb output, and nothing is listed. A windows PC, on the other hand, is able to recognize and successfully play via the USB DAC, without using any drivers (which means the Rotel is operating in USB audio class 1.0 mode).
I’ve also looked at the USB DAC compatibility list. Although Rotel RC-1570 is listed as compatible, I have no way to tell if the USB interface is the same one for the newer amp as well.
BTW - this is not the standard Volumio release (latest - 2.779), but a Debian Buster Beta, due to a bug specific to the 8GB version.
Any help would be greatly appreciated!
