Stop and then start playing an AVAudioPlayer from local file

[matiasf9]

When I stop a FSAudioStream with a stream url loaded ( [self.streamer stop] ) and then start immediately an AVAudioPlayer with a local file ( self.audioPlayer = [[AVAudioPlayer alloc] initWithData:soundData error:&error], [self.audioPlayer play]; ), the audioPlayer´s sound is stopped and the device throw me a warning ([0x384aa9dc] 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.)

This does not happen in the simulators, only in devices. In simulator, the code works perfect.
