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 zero as S/G allocation works
34	  and no preallocation is needed in most cases.
35
36	  Note that the pre-allocation size can be changed dynamically
37	  via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
