Alastor this is another issue that seems to have been caused by the changes for bug 1129882. Can you please take a look?

Hi, Jim, Do you know where is the code about handling the play icon in status bar? (In music app) Thanks!

I found the possible root cause, that is we don't send the "audiochannelchanged" event to notify the sound manager when we resume the music. Therefore, we would get the wrong current audio channel. Ex. 1. Play music - current channel = content 2. Start telephony, and pause music - current channel = telephony 3. Stop telephony, and resume music - current channel = none (X) --- Hi, Evan, Could we send this event when resume audio? Thanks!

I don't think we do anything special in the music app, except for setting the audio channel in the manifest.

Hi Alastor, The patch for Bug 1199605 will fix this.
