1 menuconfig SND_HDA_INTEL
2 tristate "Intel HD Audio"
6 Say Y here to include support for Intel "High Definition
7 Audio" (Azalia) and its compatible devices.
9 This option enables the HD-audio controller. Don't forget
10 to choose the appropriate codec options below.
12 To compile this driver as a module, choose M here: the module
13 will be called snd-hda-intel.
17 config SND_HDA_PREALLOC_SIZE
18 int "Pre-allocated buffer size for HD-audio driver"
22 Specifies the default pre-allocated buffer-size in kB for the
23 HD-audio driver. A larger buffer (e.g. 2048) is preferred
24 for systems using PulseAudio. The default 64 is chosen just
25 for compatibility reasons.
27 Note that the pre-allocation size can be changed dynamically
28 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
31 bool "Build hwdep interface for HD-audio driver"
34 Say Y here to build a hwdep interface for HD-audio driver.

39 bool "Allow dynamic codec reconfiguration (EXPERIMENTAL)"
40 depends on SND_HDA_HWDEP && EXPERIMENTAL
42 Say Y here to enable the HD-audio codec re-configuration feature.
43 This adds the sysfs interfaces to allow user to clear the whole
44 codec configuration, change the codec setup, add extra verbs,
45 and re-configure the codec dynamically.
47 config SND_HDA_INPUT_BEEP
48 bool "Support digital beep via input layer"
49 depends on INPUT=y || INPUT=SND_HDA_INTEL
51 Say Y here to build a digital beep interface for HD-audio
52 driver. This interface is used to generate digital beeps.

55 int "Digital beep registration mode (0=off, 1=on, 2=mute sw on/off)"
56 depends on SND_HDA_INPUT_BEEP=y
60 Set 0 to disable the digital beep interface for HD-audio by default.
61 Set 1 to always enable the digital beep interface for HD-audio by
62 default. Set 2 to control the beep device registration to input
63 layer using a "Beep Switch" in mixer applications.

74 bool "Support initialization patch loading for HD-audio"
75 depends on EXPERIMENTAL
78 select SND_HDA_RECONFIG
80 Say Y here to allow the HD-audio driver to load a pseudo
81 firmware file ("patch") for overriding the BIOS setup at
82 start up. The "patch" file can be specified via patch module
83 option, such as patch=hda-init.

88 bool "Build Realtek HD-audio codec support"
91 Say Y here to include Realtek HD-audio codec support in
92 snd-hda-intel driver, such as ALC880.

100 bool "Build static quirks for Realtek codecs"
101 depends on SND_HDA_CODEC_REALTEK
104 Say Y here to build the static quirks codes for Realtek codecs.
105 If you need the "model" preset that the default BIOS auto-parser
106 can't handle, turn this option on.
108 If your device works with model=auto option, basically you don't
109 need the quirk code. By turning this off, you can reduce the
110 module size quite a lot.
