18  This configuration is replaced by car_audio_configuration.xml
19
20  Notes on backward compatibility
21  - A new audioUseUnifiedConfiguration flag is added, and the default value
22  is false
23  - If OEM does not explicitly set audioUseUnifiedConfiguration to be true,
24  car_volume_groups.xml will be used, CarAudioService also queries
25  IAudioControl HAL (getBusForContext)
26  - Otherwise, CarAudioService loads the new car_audio_configuration.xml
27
28  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
29
30  Defines the all available volume groups for volume control in a car.
31  One can overlay this configuration to customize the groups.
32
33  This configuration will be populated by CarAudioService and
34  surfaced to Car Settings App and/or other volume control interfaces.
35
36  Certain constraints applied to this configuration
37    - One context should not appear in two groups
38    - All contexts are assigned
39    - One bus should not appear in two groups
40    - All gain controllers (set on each bus) in one group have same step value
41
42  It is fine that there are buses that do not appear in any group, those buses
43  may be reserved for other usages.
44
45  Important note: when overlaying this configuration,
46  make sure the resources are in the same package as CarAudioService.
