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| The old behaviour (Y) is obsolete and will be removed.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