This is by design.

When I'm using a music app ("Acme Drum Machine") and then I want to listen to some music from my iTunes library I don't expect the music app ("Acme Drum Machine") to start making noise when I pause or stop my music. This would be confusing for users. Basically the user has just paused his music (maybe to talk to someone) and then noise continues to play in his ears. The only time I want "Acme Drum Machine" to make noise is when I instruct it to.

The only exception to this rule is if the user receives a phone call. When the phone call finishes the music (from the iTunes library or a third party app) will start playing again because at no time did the user pause or stop the audio.

Cheers

Aran

Hello CoreAudio,

While our app's audio is playing, if we play music from Music app using earbud remote-control's play/pause button, our registered interruption listener is called with interruption flag being kAudioSessionBeginInterruption (i.e., we entered audio interruption).

However, pressing the play/pause button again the music will pause, so we expect that the interruption ends at the point, but the interruption listener is not called.

This can be reproduced with the Xcode sample projects:
iPhoneMultichannelMixerTest and iPhoneMixerEQGraphTest.

Is this by design: no "end of interruption" signal from remote-control at all?

It is a big problem for us because there is no way to resume app's audio automatically when the Music app is paused.
