There should be one section per audio HW module present on the platform.
|
||||
Each <module/> contains two mandatory tags: “halVersion” and “name”.
|
||||
The module "name" is the same as in previous .conf file.
|
||||
Each module must 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.
|
||||
A <route/> is defined by a set of 3 attributes:
|
||||
-"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 this route
|
||||
- <attachedDevices/>: permanently attached devices.
|
||||
The attachedDevices section is a list of devices names.
|
||||
Their names correspond to device names defined in "devicePorts" section.
|
||||
- <defaultOutputDevice/> is the device to be used when no policy rule applies
