This interface can be used for out-of-band communication with codecs for debugging purposes. config SND_HDA_RECONFIG bool "Allow dynamic codec reconfiguration" 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. 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_PATCH_LOADER bool "Support initialization patch loading for HD-audio" select FW_LOADER 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. 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. config SND_HDA_CTL_DEV_ID bool "Use the device identifier field for controls" depends on SND_HDA_INTEL help 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 The old behaviour (Y) is obsolete and will be removed.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 to not enable this option. config SND_HDA_PREALLOC_SIZE int "Pre-allocated buffer size for HD-audio driver" range 0 32768 default 0 if SND_DMA_SGBUF default 64 if !SND_DMA_SGBUF 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. endif
