OK thanks for your quick responses – really appreciate it.

Can i stop the video force the audio session and then start the video again?

[Lloydy]

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];

HI Halle,

Thanks so much for the quick response, it seems ok in the sample app, which suggests i’m doing something wrong, i’m creating my language model online as i’m trying to keep the app as small as possible – could this be anything to do with it. Also below is the reading g i get before it dean;t pick up my voice

Thanks again

Lloyd

Audio route has changed for the following reason:
There has been a change of category
The previous audio route was SpeakerAndMicrophone
This is not a case in which OpenEars performs a route change voluntarily. At the close of this function, the audio route is SpeakerAndMicrophone
