+	  Say Y to use the device identifier field for (mixer)
+	  controls (old behaviour until this option is available).
+
+	  When enabled, the multiple HDA codecs may set the device
+	  field in control (mixer) element identifiers. The use
+	  of this field is not recommended and defined for mixer controls.
+
+	  The old behaviour (Y) is obsolete and will be removed. Consider

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