| <!-- 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. |
| “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 |
