| # 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". |
