+// 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
