  	help
  	  If you don't have a sound card in your computer, you can include a
  	  driver for the PC speaker which allows it to act like a primitive
  	  sound card.
  	  This driver also replaces the pcspkr driver for beeps.
  
  	  You can compile this as a module which will be called snd-pcsp.

  	  WARNING: if you already have a soundcard, enabling this
  	  driver may lead to a problem. Namely, it may get loaded
  	  before the other sound driver of yours, making the
  	  pc-speaker a default sound device. Which is likely not
  	  what you want. To make this driver play nicely with other

  	  sound driver, you can add this in a configuration file under
  	  /etc/modprobe.d/ directory:

  	  options snd-pcsp index=2

  	  You don't need this driver if you only want your pc-speaker to beep.
  	  You don't need this driver if you have a tablet piezo beeper
  	  in your PC instead of the real speaker.

  	  Say N if you have a sound card.
  	  Say M if you don't.
  	  Say Y only if you really know what you do.

  	  You don't need this unless you're testing the hardware support
  	  of programs using the ALSA API.
  
  	  To compile this driver as a module, choose M here: the module
  	  will be called snd-dummy.

  	  Say 'Y' or 'M' to include support for the PCM loopback device.

  	  This module returns played samples back to the user space using
  	  the standard ALSA PCM device. The devices are routed 0->1 and

  	  1->0, where first number is the playback PCM device and second

  	  number is the capture device. Module creates two PCM devices and
  	  configured number of substreams (see the pcm_substreams module

  	  parameter).

  	  The loopback device allows time sychronization with an external

  	  timing source using the time shift universal control (+-20%
  	  of system time).

  	help
  	  Say Y here to enable the aggressive power-saving support of
  	  AC97 codecs.  In this mode, the power-mode is dynamically
  	  controlled at each open/close.

  	  The mode is activated by passing 'power_save=X' to the
  	  snd-ac97-codec driver module, where 'X' is the time-out
  	  value, a nonnegative integer that specifies how many
  	  seconds of idle time the driver must count before it may
  	  put the AC97 into power-save mode;  a value of 0 (zero)
  	  disables the use of this power-save mode.
  
  	  After the snd-ac97-codec driver module has been loaded,
  	  the 'power_save' parameter can be set via sysfs as follows:
  
  	    echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
  
  	  In this case, the time-out is set to 10 seconds; setting
  	  the time-out to 1 second (the minimum activation value)
  	  isn't recommended because many applications try to reopen
  	  the device frequently.  A value of 10 seconds would be a
  	  good choice for normal operations.

  	  See Documentation/sound/designs/powersave.rst for more details.
