	  Specifies the default pre-allocated buffer-size in kB for the
	  HD-audio driver.  A larger buffer (e.g. 2048) is preferred
	  for systems using PulseAudio.  The default 64 is chosen just
	  for compatibility reasons.
	  On x86 systems, the default is zero as we need no preallocation.

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