menuconfig SND_HDA_INTEL
tristate "Intel HD Audio"
select SND_PCM
select SND_VMASTER
help
Say Y here to include support for Intel "High Definition
Audio" (Azalia) and its compatible devices.
This option enables the HD-audio controller. Don't forget
to choose the appropriate codec options below.
To compile this driver as a module, choose M here: the module
will be called snd-hda-intel.
if SND_HDA_INTEL
config SND_HDA_PREALLOC_SIZE
int "Pre-allocated buffer size for HD-audio driver"
range 0 32768
default 64
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.
Note that the pre-allocation size can be changed dynamically
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
config SND_HDA_HWDEP
bool "Build hwdep interface for HD-audio driver"
select SND_HWDEP
help
Say Y here to build a hwdep interface for HD-audio driver.
This interface can be used for out-of-band communication
with codecs for debugging purposes.
config SND_HDA_RECONFIG
bool "Allow dynamic codec reconfiguration (EXPERIMENTAL)"
depends on SND_HDA_HWDEP && EXPERIMENTAL
help
Say Y here to enable the HD-audio codec re-configuration feature.
This adds the sysfs interfaces to allow user to clear the whole
codec configuration, change the codec setup, add extra verbs,
and re-configure the codec dynamically.
config SND_HDA_INPUT_BEEP
bool "Support digital beep via input layer"
depends on INPUT=y || INPUT=SND_HDA_INTEL
help
Say Y here to build a digital beep interface for HD-audio
driver. This interface is used to generate digital beeps.
config SND_HDA_INPUT_BEEP_MODE
int "Digital beep registration mode (0=off, 1=on, 2=mute sw on/off)"
depends on SND_HDA_INPUT_BEEP=y
default "1"
range 0 2
help
Set 0 to disable the digital beep interface for HD-audio by default.
Set 1 to always enable the digital beep interface for HD-audio by
default. Set 2 to control the beep device registration to input
layer using a "Beep Switch" in mixer applications.
config SND_HDA_INPUT_JACK
bool "Support jack plugging notification via input layer"
depends on INPUT=y || INPUT=SND
select SND_JACK
help
Say Y here to enable the jack plugging notification via
input layer.
config SND_HDA_PATCH_LOADER
bool "Support initialization patch loading for HD-audio"
depends on EXPERIMENTAL
select FW_LOADER
select SND_HDA_HWDEP
select SND_HDA_RECONFIG
help
Say Y here to allow the HD-audio driver to load a pseudo
firmware file ("patch") for overriding the BIOS setup at
start up. The "patch" file can be specified via patch module
option, such as patch=hda-init.
This option turns on hwdep and reconfig features automatically.
config SND_HDA_CODEC_REALTEK
bool "Build Realtek HD-audio codec support"
default y
help
Say Y here to include Realtek HD-audio codec support in
snd-hda-intel driver, such as ALC880.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-realtek.
This module is automatically loaded at probing.
config SND_HDA_ENABLE_REALTEK_QUIRKS
bool "Build static quirks for Realtek codecs"
depends on SND_HDA_CODEC_REALTEK
default y
help
Say Y here to build the static quirks codes for Realtek codecs.
If you need the "model" preset that the default BIOS auto-parser
can't handle, turn this option on.
If your device works with model=auto option, basically you don't
need the quirk code. By turning this off, you can reduce the
module size quite a lot.
config SND_HDA_CODEC_ANALOG
bool "Build Analog Device HD-audio codec support"
default y
help
Say Y here to include Analog Device HD-audio codec support in
snd-hda-intel driver, such as AD1986A.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-analog.
This module is automatically loaded at probing.
config SND_HDA_CODEC_SIGMATEL
bool "Build IDT/Sigmatel HD-audio codec support"
default y
help
Say Y here to include IDT (Sigmatel) HD-audio codec support in
snd-hda-intel driver, such as STAC9200.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-idt.
This module is automatically loaded at probing.
config SND_HDA_CODEC_VIA
bool "Build VIA HD-audio codec support"
default y
help
Say Y here to include VIA HD-audio codec support in
snd-hda-intel driver, such as VT1708.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-via.
This module is automatically loaded at probing.
config SND_HDA_CODEC_HDMI
bool "Build HDMI/DisplayPort HD-audio codec support"
select SND_DYNAMIC_MINORS
default y
help
Say Y here to include HDMI and DisplayPort HD-audio codec
support in snd-hda-intel driver. This includes all AMD/ATI,
Intel and Nvidia HDMI/DisplayPort codecs.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-hdmi.
This module is automatically loaded at probing.
config SND_HDA_CODEC_CIRRUS
bool "Build Cirrus Logic codec support"
depends on SND_HDA_INTEL
default y
help
Say Y here to include Cirrus Logic codec support in
snd-hda-intel driver, such as CS4206.
When the HD-audio driver is built as a module, the codec
support code is also built as another module,
snd-hda-codec-cirrus.
This module is automatically loaded at probing.
config SND_HDA_CODEC_CONEXANT
bool "Build Conexant HD-audio codec support"
default y
