  23          Specifies the default pre-allocated buffer-size in kB for the
  24          HD-audio driver.  A larger buffer (e.g. 2048) is preferred
  25          for systems using PulseAudio.  The default 64 is chosen just
  26          for compatibility reasons.

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