Here is the complete log

I’ll do my best to explain – basically i initialise OpenEars then suspend listening whilst i play the first video, when the video gets to the end i resume listening but i also play a silent video (Idle) on loop whilst i wait for the user to respond, once i get the response i load a new video. During the idle stage i use the following code to remove the audio from the video track – could this be affecting anything

NSArray *audioTracks = [self.idleAsset tracksWithMediaType:AVMediaTypeAudio];

// Mute all the audio tracks
NSMutableArray *allAudioParams = [NSMutableArray array];
for (AVAssetTrack *track in audioTracks) {
AVMutableAudioMixInputParameters *audioInputParams =[AVMutableAudioMixInputParameters audioMixInputParameters];
[audioInputParams setVolume:0.0 atTime:kCMTimeZero];
[audioInputParams setTrackID:[track trackID]];
[allAudioParams addObject:audioInputParams];
}
AVMutableAudioMix *audioZeroMix = [AVMutableAudioMix audioMix];
[audioZeroMix setInputParameters:allAudioParams];
