<!-- 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
