AVAudioEngine Exception

[ShaiAlkoby]

Hey,

This library works perfectly on almost all the devices, but occasionally I get an exception of the following:

Fatal Exception: com.apple.coreaudio.avfaudio required condition is false: format.sampleRate == hwFormat.sampleRate

The exception occurs on line 100 of SpeechController on the following statement:
let node = audioEngine.inputNode

stacktrace:

Interesting.. might be related to this
Do you know what kind of devices and iOS versions are throwing this error?

Now I see another exception that is occurring:
Fatal Exception: com.apple.coreaudio.avfaudio required condition is false: IsFormatSampleRateAndChannelCountValid(format)

The stack trace:

I am facing this issue on iOS 17. Any help to resolve this issue is appreciated.

Fatal Exception: com.apple.coreaudio.avfaudio
required condition is false: IsFormatSampleRateAndChannelCountValid(hwFormat)

Exception start from Line 106 of SpeechController
node.installTap(onBus: 0,
bufferSize: SpeechController.AUDIO_BUFFER_SIZE,
format: recordingFormat) { [weak self] (buffer, _) in
self?.speechRequest?.append(buffer)
}
