+# For instance, "primary" corresponds to audio.primary.<device>.so.
+# The "primary" module is mandatory and must include at least one output with

+# 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".
