	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.

	  codec configuration, change the codec setup, add extra verbs,
	  and re-configure the codec dynamically.

	bool "Support digital beep via input layer"
	depends on INPUT=y || INPUT=SND_HDA_INTEL
	help

	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.
