 # 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 "devices" are specified using strings corresponding to enums in audio.h and audio_policy.h.
-# They are concatenated by use of "|" without space or "\n".
+# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding
