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.
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.
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.
Say Y here to build a digital beep interface for HD-audio driver. This interface is used to generate digital beeps.
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.
Say Y here to enable the jack plugging notification via input layer.
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.
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.
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.
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.
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.
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.
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.
Say Y here to include Conexant HD-audio codec support in snd-hda-intel driver, such as CX20549. When the HD-audio driver is built as a module, the codec support code is also built as another module, snd-hda-codec-conexant. This module is automatically loaded at probing.
Say Y here to include Creative CA0110-IBG codec support in snd-hda-intel driver, found on some Creative X-Fi cards. When the HD-audio driver is built as a module, the codec support code is also built as another module, snd-hda-codec-ca0110. This module is automatically loaded at probing.
Say Y here to include C-Media HD-audio codec support in snd-hda-intel driver, such as CMI9880. When the HD-audio driver is built as a module, the codec support code is also built as another module, snd-hda-codec-cmedia. This module is automatically loaded at probing.
Say Y here to include Silicon Labs 3054 HD-modem codec (and compatibles) support in snd-hda-intel driver. When the HD-audio driver is built as a module, the codec support code is also built as another module, snd-hda-codec-si3054. This module is automatically loaded at probing.
Say Y here to enable the generic HD-audio codec parser in snd-hda-intel driver.
Say Y here to enable more aggressive power-saving mode on HD-audio driver. The power-saving timeout can be configured via power_save option or over sysfs on-the-fly.
The default time-out value in seconds for HD-audio automatic power-save mode. 0 means to disable the power-save mode.
