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

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