11# audio hardware module section: contains descriptors for all audio hw modules present on the
12# device. Each hw module node is named after the corresponding hw module library base name.
13# For instance, "primary" corresponds to audio.primary.<device>.so.
14# The "primary" module is mandatory and must include at least one output with
15# AUDIO_OUTPUT_FLAG_PRIMARY flag.
16# Each module descriptor contains one or more output profile descriptors and zero or more
17# input profile descriptors. Each profile lists all the parameters supported by a given output
18# or input stream category.
19# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding
20# to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n".
