+ <!-- Modules section:
+ There is one section per audio HW module present on the platform.
+ Each module section will contains two mandatory tags for audio HAL “halVersion” and “name”.
+ The module names are the same as in current .conf file:
+ “primary”, “A2DP”, “remote_submix”, “USB”
+ Each module will contain the following sections:
+ “devicePorts”: a list of device descriptors for all input and output devices accessible via this
+ module.
+ This contains both permanently attached devices and removable devices.
+ "gain": constraints applied to the millibel values:
+ - maxValueMB >= minValueMB
+ - defaultValueMB >= minValueMB && defaultValueMB <= maxValueMB
+ - (maxValueMB - minValueMB) % stepValueMB == 0
+ - (defaultValueMB - minValueMB) % stepValueMB == 0
+ “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.
+ “defaultOutputDevice”: device to be used by default when no policy rule applies
