+    Each module will contain the following sections:
+    “devicePorts”: a list of device descriptors for all input and output devices accessible via this

+    This contains both permanently attached devices and removable devices.
+    “mixPorts”: listing all output and input streams exposed by the audio HAL
+    “routes”: list of possible connections between input and output devices or between stream and
+    devices.
+    "route": is defined by an attribute:
+    -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)
+    -"sink": the sink involved in this route
+    -"sources": all the sources than can be connected to the sink via vis route
+    “attachedDevices”: permanently attached devices.
+    The attachedDevices section is a list of devices names. The names correspond to device names
+    defined in <devicePorts> section.
