iOS 10.2 callkit Fehler -> [aurioc] 892

Question

Ich benutze Callkit mit iOS10.0.1 und er funktioniert perfekt (ausgehende und eingehende Anrufe). Nach dem Update mein iPhone7 auf iOS 10.2. Ich habe nichts gehört, als ich einen eingehenden Anruf erhalte.

Für 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"); 
} 

und

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"); 
} 

und ich habe dies in meinem Log:

[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 

haben Sie eine Idee?

Answer 1

Aktivieren Sie Ihre Audiogeräte, nachdem die Audiositzung aktiviert wurde. Schreiben Sie Ihren Ton Aktivieren Anruf in Audio-Session Aktivierungsrückruf. Sie können den Block auch verwenden, um von der Audiositzung aus auf die Antwort/Bestätigung/usw. zuzugreifen.
