The alsa-kernel/usb/Kconfig file says:
| config SND_USB_USX2Y
| 	tristate "Tascam US-122, US-224 and US-428 USB driver"
| 	depends on SND && USB && (X86 || PPC || ALPHA)

AFAIK the restrictions are intended to prevent running on
architectures that don't support DMA mappings in the way this driver
uses them.  However, there shouldn't be much of a difference between
x86 and x86-64 in this regard.

You could try to replace the depends line with

	depends on SND && USB

and then recompile the driver (see "Compilation from CVS sources" in
the INSTALL file).
