+# 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".
