  29          Specifies the default pre-allocated buffer-size in kB for the
  30          HD-audio driver.  A larger buffer (e.g. 2048) is preferred
  31          for systems using PulseAudio.  The default 64 is chosen just
  32          for compatibility reasons.
  33          On x86 systems, the default is 2048 as a reasonable value for
  34          most of modern systems.
  35
  36          Note that the pre-allocation size can be changed dynamically
  37          via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
