| 1 | # Global configuration section: |
| 2 | # - before audio HAL version 3.0: |
| 3 | # lists input and output devices always present on the device |
| 4 | # as well as the output device selected by default. |
| 5 | # Devices are designated by a string that corresponds to the enum in audio.h |

| 13 | # - after and including audio HAL 3.0 the global_configuration section is included in each |
| 14 | # hardware module section. |
| 15 | # it also includes the audio HAL version of this hw module: |
| 16 | # global_configuration { |
| 17 | # ... |
| 18 | # audio_hal_version <major.minor> # audio HAL version in e.g. 3.0 |
| 19 | # } |
| 20 | # other attributes (attached devices, default device) have to be included in the |
| 21 | # global_configuration section of each hardware module |
| 22 | |
| 23 | |
| 24 | # audio hardware module section: contains descriptors for all audio hw modules present on the |
| 25 | # device. Each hw module node is named after the corresponding hw module library base name. |
| 26 | # For instance, "primary" corresponds to audio.primary.<device>.so. |
| 27 | # The "primary" module is mandatory and must include at least one output with |
| 28 | # AUDIO_OUTPUT_FLAG_PRIMARY flag. |
| 29 | # Each module descriptor contains one or more output profile descriptors and zero or more |
| 30 | # input profile descriptors. Each profile lists all the parameters supported by a given output |
| 31 | # or input stream category. |
| 32 | # The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding |
| 33 | # to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n". |
