Using AEPlaythroughChannel with speaker makes noise about theamazingaudioengine HOT 3 CLOSED

Thanks for your reply, michaeltyson.
I have tried that, but if I set the voiceProcessingEnabled to YES, it always give the "Timed out while performing message exchange", and will make the app crash later.
Here is how I configure the AEAudioController:

_audioController = [[AEAudioController alloc] initWithAudioDescription:[AEAudioController nonInterleaved16BitStereoAudioDescription] inputEnabled:YES];

if([AEAudioController voiceProcessingAvailable]){
    self.audioController.voiceProcessingEnabled = YES;
}

[self.audioController start:NULL];

_playthroughChannel = [[AEPlaythroughChannel alloc] initWithAudioController:_audioController];
self.playthroughChannel.volume = 1.0;
[self.audioController addInputReceiver:self.playthroughChannel];
[self.audioController addChannels:[NSArray arrayWithObject:self.playthroughChannel]];

if(self.audioController.inputGainAvailable){
    [self.audioController setInputGain:1.0];
}

and here is the log:

Oops - good catch. Fixed in SHA fe2c96a - also, I probably steered you astray by pointing you to the property, as there's an initialiser that's more efficient: http://theamazingaudioengine.com/doc/interface_a_e_audio_controller.html#a828ada216ef19ad92841e7891b6ceab5
