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

44 depends on SND_HDA_HWDEP
46 Say Y here to enable the HD-audio codec re-configuration feature.

83 firmware file ("patch") for overriding the BIOS setup at
84 start up. The "patch" file can be specified via patch module
85 option, such as patch=hda-init.
87 This option turns on hwdep and reconfig features automatically.
