iOS 10.2 ошибка callkit -> [aurioc] 892

Question

Я использую Callkit с iOS10.0.1, и он отлично работает (исходящие и входящие вызовы). После обновления моего iPhone7 до iOS 10.2. Когда я получаю входящий звонок, я ничего не слышал.

Для AudioController:

try { 
    // Configure the audio session 
    AVAudioSession *sessionInstance = [AVAudioSession sharedInstance]; 

    // we are going to play and record so we pick that category 
    NSError *error = nil; 
    [sessionInstance setCategory:AVAudioSessionCategoryPlayAndRecord error:&error]; 
    XThrowIfError((OSStatus)error.code, "couldn't set session's audio category"); 

    // set the mode to voice chat 
    [sessionInstance setMode:AVAudioSessionModeVoiceChat error:&error]; 
    XThrowIfError((OSStatus)error.code, "couldn't set session's audio mode"); 

    // set the buffer duration to 5 ms 
    NSTimeInterval bufferDuration = .005; 
    [sessionInstance setPreferredIOBufferDuration:bufferDuration error:&error]; 
    XThrowIfError((OSStatus)error.code, "couldn't set session's I/O buffer duration"); 

    // set the session's sample rate 
    [sessionInstance setPreferredSampleRate:44100 error:&error]; 
    XThrowIfError((OSStatus)error.code, "couldn't set session's preferred sample rate"); 

    // add interruption handler 
    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(handleInterruption:) 
               name:AVAudioSessionInterruptionNotification 
               object:sessionInstance]; 

    // we don't do anything special in the route change notification 
    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(handleRouteChange:) 
               name:AVAudioSessionRouteChangeNotification 
               object:sessionInstance]; 

    // if media services are reset, we need to rebuild our audio chain 
    [[NSNotificationCenter defaultCenter] addObserver: self 
              selector: @selector(handleMediaServerReset:) 
               name: AVAudioSessionMediaServicesWereResetNotification 
               object: sessionInstance]; 
} 

catch (CAXException &e) { 
    NSLog(@"Error returned from setupAudioSession: %d: %s", (int)e.mError, e.mOperation); 
} 
catch (...) { 
    NSLog(@"Unknown error returned from setupAudioSession"); 
}

try { 
    // Create a new instance of Apple Voice Processing IO 

    AudioComponentDescription desc; 
    desc.componentType = kAudioUnitType_Output; 
    desc.componentSubType = kAudioUnitSubType_VoiceProcessingIO; 
    desc.componentManufacturer = kAudioUnitManufacturer_Apple; 
    desc.componentFlags = 0; 
    desc.componentFlagsMask = 0; 

    AudioComponent comp = AudioComponentFindNext(NULL, &desc); 
    XThrowIfError(AudioComponentInstanceNew(comp, &_rioUnit), "couldn't create a new instance of Apple Voice Processing IO"); 

    // Enable input and output on Apple Voice Processing IO 
    // Input is enabled on the input scope of the input element 
    // Output is enabled on the output scope of the output element 

    UInt32 one = 1; 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioOutputUnitProperty_EnableIO, kAudioUnitScope_Input, 1, &one, sizeof(one)), "could not enable input on Apple Voice Processing IO"); 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioOutputUnitProperty_EnableIO, kAudioUnitScope_Output, 0, &one, sizeof(one)), "could not enable output on Apple Voice Processing IO"); 

    // Explicitly set the input and output client formats 
    // sample rate = 44100, num channels = 1, format = 32 bit floating point 

    CAStreamBasicDescription ioFormat = CAStreamBasicDescription(44100, 1, CAStreamBasicDescription::kPCMFormatFloat32, false); 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioUnitProperty_StreamFormat, kAudioUnitScope_Output, 1, &ioFormat, sizeof(ioFormat)), "couldn't set the input client format on Apple Voice Processing IO"); 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioUnitProperty_StreamFormat, kAudioUnitScope_Input, 0, &ioFormat, sizeof(ioFormat)), "couldn't set the output client format on Apple Voice Processing IO"); 

    // Set the MaximumFramesPerSlice property. This property is used to describe to an audio unit the maximum number 
    // of samples it will be asked to produce on any single given call to AudioUnitRender 
    UInt32 maxFramesPerSlice = 4096; 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioUnitProperty_MaximumFramesPerSlice, kAudioUnitScope_Global, 0, &maxFramesPerSlice, sizeof(UInt32)), "couldn't set max frames per slice on Apple Voice Processing IO"); 

    // Get the property value back from Apple Voice Processing IO. We are going to use this value to allocate buffers accordingly 
    UInt32 propSize = sizeof(UInt32); 
    XThrowIfError(AudioUnitGetProperty(_rioUnit, kAudioUnitProperty_MaximumFramesPerSlice, kAudioUnitScope_Global, 0, &maxFramesPerSlice, &propSize), "couldn't get max frames per slice on Apple Voice Processing IO"); 

    // We need references to certain data in the render callback 
    // This simple struct is used to hold that information 

    cd.rioUnit = _rioUnit; 
    cd.muteAudio = &_muteAudio; 
    cd.audioChainIsBeingReconstructed = &_audioChainIsBeingReconstructed; 

    // Set the render callback on Apple Voice Processing IO 
    AURenderCallbackStruct renderCallback; 
    renderCallback.inputProc = performRender; 
    renderCallback.inputProcRefCon = NULL; 
    XThrowIfError(AudioUnitSetProperty(_rioUnit, kAudioUnitProperty_SetRenderCallback, kAudioUnitScope_Input, 0, &renderCallback, sizeof(renderCallback)), "couldn't set render callback on Apple Voice Processing IO"); 

    // Initialize the Apple Voice Processing IO instance 
    XThrowIfError(AudioUnitInitialize(_rioUnit), "couldn't initialize Apple Voice Processing IO instance"); 
} 

catch (CAXException &e) { 
    NSLog(@"Error returned from setupIOUnit: %d: %s", (int)e.mError, e.mOperation); 
} 
catch (...) { 
    NSLog(@"Unknown error returned from setupIOUnit"); 
} 

и у меня есть это в моем журнале:

[aurioc] 892: failed: '!pri' (enable 3, outf< 1 ch, 44100 Hz, Float32> inf< 1 ch, 44100 Hz, Float32>) 
Error returned from setupIOUnit: 561017449: couldn't initialize Apple Voice Processing IO instance 

у вас есть идея?

Включите звуковые устройства после активации сеанса аудио. Запишите свой звонок для включения звука в сеансе активации аудиозаписей. Вы также можете использовать блок для вызова из сеанса аудио для ответа/отмены/и т. Д.
