menuconfig SND_HDA_INTEL
	tristate "Intel HD Audio"
	select SND_PCM
	select SND_VMASTER
	select SND_KCTL_JACK
	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.

config SND_HDA_DSP_LOADER
	bool

config SND_HDA_PREALLOC_SIZE
	int "Pre-allocated buffer size for HD-audio driver"
	range 0 32768
	default 64
	help
	  Specifies the default pre-allocated buffer-size in kB for the
	  HD-audio driver.  A larger buffer (e.g. 2048) is preferred
	  for systems using PulseAudio.  The default 64 is chosen just
	  for compatibility reasons.

	  Note that the pre-allocation size can be changed dynamically
	  via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.

config SND_HDA_HWDEP
	bool "Build hwdep interface for HD-audio driver"
	select SND_HWDEP
	help
	  Say Y here to build a hwdep interface for HD-audio driver.
	  This interface can be used for out-of-band communication
	  with codecs for debugging purposes.

config SND_HDA_RECONFIG
	bool "Allow dynamic codec reconfiguration"
	depends on SND_HDA_HWDEP
	help
	  Say Y here to enable the HD-audio codec re-configuration feature.
	  This adds the sysfs interfaces to allow user to clear the whole
	  codec configuration, change the codec setup, add extra verbs,
	  and re-configure the codec dynamically.

config SND_HDA_INPUT_BEEP
	bool "Support digital beep via input layer"
	depends on INPUT=y || INPUT=SND_HDA_INTEL
	help
	  Say Y here to build a digital beep interface for HD-audio
	  driver. This interface is used to generate digital beeps.

config SND_HDA_INPUT_BEEP_MODE
	int "Digital beep registration mode (0=off, 1=on)"
	depends on SND_HDA_INPUT_BEEP=y
	default "1"
	range 0 1
	help
	  Set 0 to disable the digital beep interface for HD-audio by default.
	  Set 1 to always enable the digital beep interface for HD-audio by
	  default.

config SND_HDA_INPUT_JACK
	bool "Support jack plugging notification via input layer"
	depends on INPUT=y || INPUT=SND
	select SND_JACK

	select SND_HDA_RECONFIG
	help
	  Say Y here to allow the HD-audio driver to load a pseudo
	  firmware file ("patch") for overriding the BIOS setup at
	  start up.  The "patch" file can be specified via patch module
	  option, such as patch=hda-init.

	  This option turns on hwdep and reconfig features automatically.

	tristate "Build Realtek HD-audio codec support"
	select SND_HDA_GENERIC
