| Say Y here to build a hwdep interface for HD-audio driver. |

| config SND_HDA_RECONFIG |
| bool "Allow dynamic codec reconfiguration" |
| help |
| 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. |

| 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| The old behaviour (Y) is obsolete and will be removed.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 |

| 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. |
| 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. |
