12 tristate "HD Audio PCI"
15 select SND_INTEL_NHLT if ACPI
17 Say Y here to include support for Intel "High Definition
18 Audio" (Azalia) and its compatible devices.
20 This option enables the HD-audio controller. Don't forget
21 to choose the appropriate codec options below.
23 To compile this driver as a module, choose M here: the module
24 will be called snd-hda-intel.
26 config SND_HDA_INTEL_DETECT_DMIC
27 bool "DMIC detection and probe abort"
28 depends on SND_HDA_INTEL
30 Say Y to detect digital microphones on SKL+ devices. DMICs
31 cannot be handled by the HDaudio legacy driver and are
32 currently only supported by the SOF driver.
36 tristate "NVIDIA Tegra HD Audio"
39 select SND_HDA_ALIGNED_MMIO
41 Say Y here to support the HDA controller present in NVIDIA

69 enables the feature just for the patch loader below.
70 If you need the traditional sysfs entries for the manual interaction,
71 turn on CONFIG_SND_HDA_HWDEP as well.
