// 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.
