Bug: RTFaceLogin sometimes kept running and talking after starting RoboTutor

[JackMostow]

2022-10-06 meeting 2 with Kathi Kuehr:
On tablets 6111000885 and 6111000955, FaceLogin sometimes kept running and talking after starting RoboTutor.

[JackMostow]

Possible fix: exit RTFaceLogin when launch RoboTutor? or just kill culprit process (audio playback?)

[JackMostow]

Rohan propose set audio app state to null when launch RoboTutor.
Asks if lasts throughout RoboTutor session or just long audio taking awhile to finish.

[JackMostow]

Answer: lasted several seconds for Bhuvan in emulator, i.e. not just "Let's get started."

Propose: just before launching RoboTutor:
If still playing audio or video, wait [3] seconds (long enough to finish "Hebu tuanze" ("Let's get started").
Then stop (i.e. including deallocation of memory) audio and video (no-op if not playing).

[JackMostow]

Wait and see if recurs. If it does, we hope the log will shed light on when and why. Maybe we'll even get a stack trace.
