Subject [jira] [Comment Edited] (CB-7599) [Media][iOS 8] Audio exceptions generated when playing audio files

-----------------------------------------------------------

For anybody else who needs a workaround for a similar issue, here's what I ended up doing
out of expediency:

Rather than allow any of the short clips to terminate on their own (by calling .play() and
letting them run their course), I stop the clips shortly before they would terminate using
a combination of .play and setTimeout. Here's a generalized example:

{code}
setTimeout( function(){ clip.stop(); }, ( clip.getDuration() * 1000 - 100) );
clip.play();
{code}
This prevents the audio session from being deactivated, so that cryptic XCode error is never
triggered. It hurts to look at, but it works. Basically, avoid letting the audio clip stop
on its own (keep it running hot).

I would welcome a better solution, but I'll leave this one here for other non-Objective-C-minded
developers.

> In iOS8, several users have noticed that applications with audio that previously worked
in iOS7, are generating exceptions in iOS8.
> In my app, it is when pausing one audio, and after a short timeout, playing another audio.
The exception:
> 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.
> In another case (Paul's comment below), it was when scrubbing through a single audio
file. The error:
> ERROR: [0x109894000] 79: AudioQueuePrime posting message to kill mediaserverd
