麦克风停止在iOS 13和Xcode 11上运行

Question

在更新到iOS 13之后，麦克风停止工作，这种方法不起作用：

- (void)installTapOnBus:(AVAudioNodeBus)bus bufferSize:(AVAudioFrameCount)bufferSize format:(AVAudioFormat * __nullable)format block:(AVAudioNodeTapBlock)tapBlock;

我的代码：

[self.audioInputNode installTapOnBus:0 bufferSize:(AVAudioFrameCount)self.numSoundFrames format:[self.audioPlayerNode outputFormatForBus:0] block:^(AVAudioPCMBuffer *buffer, AVAudioTime *time) {
// doesn't come here

控制台输出：

[avae]            AVAEInternal.h:76    required condition is false: [AVAudioEngineGraph.mm:2025:InstallTapOnNode: (CAStreamBasicDescription::IsEquivalent(*inputHWFormatASBD, *tapASBD))]
