CONFIG_SND_HDA_PREALLOC_SIZE is used only by controller.c in sound/hda/common, hence it depends on CONFIG_SND_HDA. Move the definition to the right place inside SND_HDA if/endif block in sound/hda/common/Kconfig.

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.

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The old behaviour (Y) is obsolete and will be removed.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

to not enable this option.

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.
