menu "HD-Audio" config SND_HDA tristate select SND_PCM select SND_VMASTER select SND_KCTL_JACK config SND_HDA_INTEL tristate "HD Audio PCI" depends on SND_PCI select SND_HDA 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. config SND_HDA_TEGRA tristate "Tegra HD Audio" select SND_HDA help Say Y here to support the HDA controller present in Nvidia Tegra SoCs This options enables support for the HD Audio controller present in some Nvidia Tegra SoCs, used to communicate audio to the HDMI output. To compile this driver as a module, choose M here: the module will be called snd-hda-tegra. if SND_HDA config SND_HDA_DSP_LOADER bool 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" depends on SND_HDA_HWDEP 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 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)" depends on SND_HDA_INPUT_BEEP=y default "1" range 0 1 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. 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" 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 tristate "Build Realtek HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include Realtek HD-audio codec support in snd-hda-intel driver, such as ALC880. config SND_HDA_CODEC_ANALOG tristate "Build Analog Device HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include Analog Device HD-audio codec support in snd-hda-intel driver, such as AD1986A. config SND_HDA_CODEC_SIGMATEL tristate "Build IDT/Sigmatel HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include IDT (Sigmatel) HD-audio codec support in snd-hda-intel driver, such as STAC9200. config SND_HDA_CODEC_VIA tristate "Build VIA HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include VIA HD-audio codec support in snd-hda-intel driver, such as VT1708. config SND_HDA_CODEC_HDMI tristate "Build HDMI/DisplayPort HD-audio codec support" select SND_DYNAMIC_MINORS default y help Say Y or M 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. config SND_HDA_I915 bool "Build Display HD-audio controller/codec power well support for i915 cards" depends on DRM_I915 help Say Y here to include full HDMI and DisplayPort HD-audio controller/codec power-well support for Intel Haswell graphics cards based on the i915 driver. Note that this option must be enabled for Intel Haswell C+ stepping machines, otherwise the GPU audio controller/codecs will not be initialized or damaged when exit from S3 mode. config SND_HDA_CODEC_CIRRUS tristate "Build Cirrus Logic codec support" select SND_HDA_GENERIC help Say Y or M here to include Cirrus Logic codec support in snd-hda-intel driver, such as CS4206. config SND_HDA_CODEC_CONEXANT tristate "Build Conexant HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include Conexant HD-audio codec support in snd-hda-intel driver, such as CX20549. config SND_HDA_CODEC_CA0110 tristate "Build Creative CA0110-IBG codec support" select SND_HDA_GENERIC help Say Y or M here to include Creative CA0110-IBG codec support in snd-hda-intel driver, found on some Creative X-Fi cards. config SND_HDA_CODEC_CA0132 tristate "Build Creative CA0132 codec support" help Say Y or M here to include Creative CA0132 codec support in snd-hda-intel driver. config SND_HDA_CODEC_CA0132_DSP bool "Support new DSP code for CA0132 codec" depends on SND_HDA_CODEC_CA0132 && FW_LOADER select SND_HDA_DSP_LOADER help Say Y here to enable the DSP for Creative CA0132 for extended features like equalizer or echo cancellation. Note that this option requires the external firmware file (ctefx.bin). config SND_HDA_CODEC_CMEDIA tristate "Build C-Media HD-audio codec support" select SND_HDA_GENERIC help Say Y or M here to include C-Media HD-audio codec support in snd-hda-intel driver, such as CMI9880. config SND_HDA_CODEC_SI3054 tristate "Build Silicon Labs 3054 HD-modem codec support" help Say Y or M here to include Silicon Labs 3054 HD-modem codec (and compatibles) support in snd-hda-intel driver. config SND_HDA_GENERIC tristate "Enable generic HD-audio codec parser" help Say Y or M here to enable the generic HD-audio codec parser in snd-hda-intel driver. config SND_HDA_POWER_SAVE_DEFAULT int "Default time-out for HD-audio power-save mode" depends on PM default 0 help The default time-out value in seconds for HD-audio automatic power-save mode. 0 means to disable the power-save mode. endif endmenu
