101 There should be one section per audio HW module present on the platform.
102 Each <module/> contains two mandatory tags: “halVersion” and “name”.
103 The module "name" is the same as in previous .conf file.
104 Each module must contain the following sections:
105 - <devicePorts/>: a list of device descriptors for all
106 input and output devices accessible via this module.
107 This contains both permanently attached devices and removable devices.
108 - <mixPorts/>: listing all output and input streams exposed by the audio HAL
109 - <routes/>: list of possible connections between input
110 and output devices or between stream and devices.
111 A <route/> is defined by a set of 3 attributes:
112 -"type": mux|mix means all sources are mutual exclusive (mux) or can be mixed (mix)
113 -"sink": the sink involved in this route
114 -"sources": all the sources than can be connected to the sink via this route
115 - <attachedDevices/>: permanently attached devices.
116 The attachedDevices section is a list of devices names.
117 Their names correspond to device names defined in "devicePorts" section.
118 - <defaultOutputDevice/> is the device to be used when no policy rule applies
