Description

Spatial voice does not work reliably for users that log into adjacent regions.

Reproduction steps

Repro: (this is not a reliable repro

  1. UserA (testerd5) logged into WebRTC1 on Aditi (Windows 10, 7.1.11.11074622243 ExtraFPS)
  2. UserB (testerd1) logged into WebRTC2 on Aditi (Windows 11, 7.1.11.11074622243 ExtraFPS)
  3. UserA and UserB cannot hear each other across the region boundary
  4. UserB crossed into WebRTC2
  5. UserB can see their own voice waves.
  6. UserB cannot hear or see voice waves from testerd5.

Viewer logs with debugging enabled:
UserA WebRTC1 SecondLife.log

UserB WebRTC2 to WebRTC1 SecondLife.log

Research direction

Start by reviewing the attached UserA WebRTC1 SecondLife.log and UserB WebRTC2 to WebRTC1 SecondLife.log, then try the reported two-user scenario across the WebRTC1/WebRTC2 boundary. Done means adjacent-region users can reliably hear each other and see one another's spatial voice waves.
