AVassetExportSession kills my audio.

Question

Hi all. when I start –exportAsynchronouslyWithCompletionHandler: method of AVassetExportSession my audio is stops playing. I am using AudioQueue and OpenAL they both needs to be restarted after beginning export session. Is there any trick to make them work without restarting audios?

Well. Nobody has answered to me, so I will answer myself. Figured that when exporting with AVAssetExportSession it creates its own audio queue therefore it kills my, so before starting my queue all I need is to set some properties to AudioSession.

 AudioSessionInitialize(CFRunLoopGetCurrent(), 
                             kCFRunLoopCommonModes, 
                             NULL, 
                             NULL);
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, 
                              sizeof(kAudioSessionCategory_MediaPlayback), 
                              &(int) 
                              {kAudioSessionCategory_MediaPlayback});
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, 
                              sizeof (UInt32), 
                              &(UInt32) 
                              {1});
AudioSessionSetActive(YES);
