+ default 64
+ help
+ 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.
+
+ Note that the pre-allocation size can be changed dynamically
+ via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
