-# 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. :
