// Note: When transitioning to loading of XML configs, either keep the configuration

// of the remote submix sources from this static configuration, or update the XML
|
||||
// config to match it. There are two reasons for that:
|
||||
// 1. The canonical r_submix configuration only lists 'STEREO' and '48000',
|
||||
// however the framework attempts to open streams for other sample rates
|
||||
// as well. The legacy r_submix implementation allowed that, but libaudiohal@aidl
|
||||
// will not find a mix port to use. Because of that, list all channel
|
||||
// masks and sample rates that the legacy implementation allowed.
|
||||
// 2. The legacy implementation had a hard limit on the number of routes (10),
|
||||
// and this is checked indirectly by AudioPlaybackCaptureTest#testPlaybackCaptureDoS
|
||||
// CTS test. Instead of hardcoding the number of routes, we can use
|
||||
// "maxOpen/ActiveStreamCount" to enforce a similar limit. However, the canonical
|
||||
// XML file lacks this specification.
