--------------------------------------------------------------
We arrived to the same conclusion as [~Stryker908] and GitHub's user
ionut-movila in his PR: https://github.com/apache/cordova-plugin-media/pull/33.
The problem for us is not only that when a media is finished it's stopping all
the others, but also that *.release()* is killing all sounds running, even if
they were played by another plugin (or by WebView's default webaudio system),
triggering a descriptive:
{code}
AVAudioSession.mm:646: -[AVAudioSession setActive:withOptions:error:]:
Deactivating an audio session that has running I/O. All I/O should be stopped
or paused prior to deactivating the audio session.
{code}
We found that *AVAudioSession* is a singleton for the whole app (cf.
https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioSession_ClassReference/).
Apple says:
{quote}
Most apps never need to deactivate their audio session explicitly. Important
exceptions include VoIP (Voice over Internet Protocol) apps, turn-by-turn
navigation apps, and, in some cases, recording apps.
{quote}
(cf.
https://developer.apple.com/library/ios/documentation/Audio/Conceptual/AudioSessionProgrammingGuide/ConfiguringanAudioSession/ConfiguringanAudioSession.html)
In our project we don't use the recording capacities. We removed all:
{code}
avSession setActive:NO
{code}
and it's is working pretty well (as in PR https://github.com/ionut-movila).
Additionally it may be worth to update the comment:
*// returns whether or not audioSession is available - creates it if necessary*
to something like:
*// returns whether or not audioSession is available - retrieve the instance
(app singleton) if necessary*.

> [Media] CDVSound Kills any and all playing sound files when a single file
> finishes
> ----------------------------------------------------------------------------------
>
> Key: CB-7684
> URL: https://issues.apache.org/jira/browse/CB-7684
> Project: Apache Cordova
> Issue Type: Sub-task
> Components: Plugin Media
> Affects Versions: 3.5.0
> Environment: iOS
> Reporter: Nathan Stryker
>
> The CDVSound file will kill all playing media files when ever a single file
> completes playing. The issue is around like 691 in the method
> "AudioDidFinishPlaying", with the code:
> if (self.avSession) {
> [self.avSession setActive:NO error:nil];
> }
> The reason I think this is a bug is that if a user as Music file A playing in
> a loop and Music file B plays, when B completes the "setActive:NO" will kill
> the avSession of both A and B.
