# Template audio policy configuration file

#

# Global configuration section:

# - before audio HAL version 3.0:

#   lists input and output devices always present on the device

#   as well as the output device selected by default.

#   Devices are designated by a string that corresponds to the enum in audio.h

#

#  global_configuration {

#    attached_output_devices AUDIO_DEVICE_OUT_SPEAKER

#    default_output_device AUDIO_DEVICE_OUT_SPEAKER

#    attached_input_devices AUDIO_DEVICE_IN_BUILTIN_MIC|AUDIO_DEVICE_IN_REMOTE_SUBMIX

#  }

#

# - after and including audio HAL 3.0 the global_configuration section is included in each

#   hardware module section.

#   it also includes the audio HAL version of this hw module:

#  global_configuration {

#    ...

#     audio_hal_version <major.minor>  # audio HAL version in e.g. 3.0

#  }

#   other attributes (attached devices, default device) have to be included in the

#   global_configuration section of each hardware module

# audio hardware module section: contains descriptors for all audio hw modules present on the

# device. Each hw module node is named after the corresponding hw module library base name.

# For instance, "primary" corresponds to audio.primary.<device>.so.

# The "primary" module is mandatory and must include at least one output with

# AUDIO_OUTPUT_FLAG_PRIMARY flag.

# Each module descriptor contains one or more output profile descriptors and zero or more

# input profile descriptors. Each profile lists all the parameters supported by a given output

# or input stream category.

# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding

# to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n".

#

# For audio HAL version posterior to 3.0 the following sections or sub sections can be present in

# a hw module section:

# - A "global_configuration" section: see above

# - Optionally a "devices" section:

#   This section contains descriptors for audio devices with attributes like an address or a

#   gain controller. The syntax for the devices section and device descriptor is as follows:

#    devices {

#      <device name> {              # <device name>: any string without space

#        type <device type>         # <device type> e.g. AUDIO_DEVICE_OUT_SPEAKER

#        address <address>          # optional: device address, char string less than 64 in length

#      }

#    }

# - one or more "gains" sections can be present in a device descriptor section.

#   If present, they describe the capabilities of gain controllers attached to this input or

#   output device. e.g. :

#   <device name> {                  # <device name>: any string without space

#     type <device type>             # <device type> e.g. AUDIO_DEVICE_OUT_SPEAKER

#     address <address>              # optional: device address, char string less than 64 in length

#     gains {

#       <gain name> {

#         mode <gain modes supported>              # e.g. AUDIO_GAIN_MODE_CHANNELS

#         channel_mask <controlled channels>       # needed if mode AUDIO_GAIN_MODE_CHANNELS

#         min_value_mB <min value in millibel>

#         max_value_mB <max value in millibel>

#         default_value_mB <default value in millibel>

#         step_value_mB <step value in millibel>

#         min_ramp_ms <min duration in ms>         # needed if mode AUDIO_GAIN_MODE_RAMP

#         max_ramp_ms <max duration ms>            # needed if mode AUDIO_GAIN_MODE_RAMP

#       }

#     }

#   }

# - when a device descriptor is present, output and input profiles can refer to this device by

# its name in their "devices" section instead of specifying a device type. e.g. :

#   outputs {

#     primary {

#       sampling_rates 44100

#       channel_masks AUDIO_CHANNEL_OUT_STEREO

#       formats AUDIO_FORMAT_PCM_16_BIT

#       devices <device name>

#       flags AUDIO_OUTPUT_FLAG_PRIMARY

#     }

#   }
