Do you know who's vendor id is this? ESS Sabre is a DAC chip with I2S
input, I'm not aware of any product from ESS under Sabre brand that
would include USB interface. (?) So likely the USB interface is sourced
from somewhere else...
It is good to check with "lsusb -vvv" if the device flags DSD altsetting
as raw. Then you know it'll work with the auto-detection code and
doesn't break so easily if firmware update changes altsettings (not
uncommon to happen).
