then you can fake the subvendor id (VT1724_SUBDEVICE_AUREON71_SPACE) defined in aureon.h by replacing it with your card's id, which is shown in the EEPROM output in /proc/asound/card0/ice1724. we might need to tune up eeprom entries to match with the actual hardware, but in theory it should be ok as it is.
