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.
