In linux kernel since version 2.6.29 (release Date: 2009-03-23)
Say Y here to enable the HD-audio codec re-configuration feature.
It allows user to clear the whole codec configuration, change the
codec setup, add extra verbs, and re-configure the codec dynamically.
Note that this item alone doesn't provide the sysfs interface, but
enables the feature just for the patch loader below.
If you need the traditional sysfs entries for the manual interaction,
turn on CONFIG_SND_HDA_HWDEP as well.
