The log I attached to comment 2 is about bug 894530 and bug 864188. We should focus on why Music player was dead.

retriage: corner case. minus

I'd like to steal the bug, Eric.

The UX behaviour has been changed for a while. After disconnecting A2DP, Music App should pause the music in case of the audio is routed to speaker at a high volume and scare the user away. I tried with the latest build of both v1.2 and m-c. The routing path seems great and no crash. Walter, can you or other QA help to verify it again?

The behavior is changed as Gina described. I think currently this behavior is hard to reproduce.

That's great! Thanks, Walter.
