    reference_rate	- reference sample rate, 44100 or 48000 (default)

    multiple		- multiple to ref. sample rate, 1 or 2 (default)

    subsystem		- override the PCI SSID for probing; the value

			  consists of SSVID << 16 | SSDID.  The default is

			  zero, which means no override.



    This module supports multiple cards.
