ALSA: add Studio Evolution SE6X support

	  To compile this driver as a module, choose M here: the module

	  will be called snd-rme9652.

config SND_SE6X

	tristate "Studio Evolution SE6X"

	depends on SND_OXYGEN=n && SND_VIRTUOSO=n  # PCI ID conflict

	select SND_OXYGEN_LIB

	select SND_PCM

	select SND_MPU401_UART

	help

	  Say Y or M here only if you actually have this sound card.

config SND_SIS7019

	tristate "SiS 7019 Audio Accelerator"

	depends on X86_32
