76 There should be one section per audio HW module present on the platform.
77 Each <module/> contains two mandatory tags: “halVersion” and “name”.
78 The module "name" is the same as in previous .conf file.
79 Each module must contain the following sections:
80 - <devicePorts/>: a list of device descriptors for all
81 input and output devices accessible via this module.
82 This contains both permanently attached devices and removable devices.
83 - <mixPorts/>: listing all output and input streams exposed by the audio HAL
84 - <routes/>: list of possible connections between input
85 and output devices or between stream and devices.
86 A <route/> is defined by a set of 3 attributes:
87 -"type": mux|mix means all sources are mutual exclusive (mux) or can be mixed (mix)
88 -"sink": the sink involved in this route
89 -"sources": all the sources than can be connected to the sink via this route
90 - <attachedDevices/>: permanently attached devices.
91 The attachedDevices section is a list of devices names.
92 Their names correspond to device names defined in "devicePorts" section.
93 - <defaultOutputDevice/> is the device to be used when no policy rule applies
