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

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