  41           If you don't have a sound card in your computer, you can include a
  42           driver for the PC speaker which allows it to act like a primitive
  43           sound card.
  44           This driver also replaces the pcspkr driver for beeps.
  45
  46           You can compile this as a module which will be called snd-pcsp.
  47
  48           WARNING: if you already have a soundcard, enabling this
  49           driver may lead to a problem. Namely, it may get loaded
  50           before the other sound driver of yours, making the
  51           pc-speaker a default sound device. Which is likely not
  52           what you want. To make this driver play nicely with other
  53           sound driver, you can add this in a configuration file under
  54           /etc/modprobe.d/ directory:
  55           options snd-pcsp index=2
  56
  57           You don't need this driver if you only want your pc-speaker to beep.
  58           You don't need this driver if you have a tablet piezo beeper
  59           in your PC instead of the real speaker.
  60
  61           Say N if you have a sound card.
  62           Say M if you don't.
  63           Say Y only if you really know what you do.

  72           You don't need this unless you're testing the hardware support
  73           of programs using the ALSA API.

  83           This module returns played samples back to the user space using
  84           the standard ALSA PCM device. The devices are routed 0->1 and
  85           1->0, where first number is the playback PCM device and second
  86           number is the capture device. Module creates two PCM devices and
  87           configured number of substreams (see the pcm_substreams module
  88           parameter).
  89
  90           The loopback device allows time sychronization with an external
  91           timing source using the time shift universal control (+-20%
  92           of system time).

 188         help
 189           Say Y here to enable the aggressive power-saving support of
 190           AC97 codecs.  In this mode, the power-mode is dynamically
 191           controlled at each open/close.
 192
 193           The mode is activated by passing 'power_save=X' to the
 194           snd-ac97-codec driver module, where 'X' is the time-out
 195           value, a nonnegative integer that specifies how many
 196           seconds of idle time the driver must count before it may
 197           put the AC97 into power-save mode;  a value of 0 (zero)
 198           disables the use of this power-save mode.
 199
 200           After the snd-ac97-codec driver module has been loaded,
 201           the 'power_save' parameter can be set via sysfs as follows:
 202
 203             echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
 204
 205           In this case, the time-out is set to 10 seconds; setting
 206           the time-out to 1 second (the minimum activation value)
 207           isn't recommended because many applications try to reopen
 208           the device frequently.  A value of 10 seconds would be a
 209           good choice for normal operations.
