This seems more like an AudioChannel bug. Moving components so they can take a look.

We think that that behavior in 2.5 when music control does not appear in notification drawer after closing camera app is incorrect, so Bug 1226747 has been failed.

[Alastor Wu [:alwu]]

Music would be still playing, and the control icon in the notification bar is also correct.
