	help
	  Say Y here to include support for Intel "High Definition
	  Audio" (Azalia) and its compatible devices.

	  This option enables the HD-audio controller.  Don't forget
	  to choose the appropriate codec options below.

	  To compile this driver as a module, choose M here: the module
	  will be called snd-hda-intel.
