iOS crash : specialized RecorderBytesStreamEngine.attach(result:sampleRate:) com.apple.coreaudio.avfaudio - required condition is false: nullptr == Tap()

[Tom3652]

I would like to come back to #463 previously fixed and i agree !

However it introduced a new bug still under the same logic apparently :
specialized RecorderBytesStreamEngine.attach(result:sampleRate:) com.apple.coreaudio.avfaudio - required condition is false: nullptr == Tap()

Fatal Exception: com.apple.coreaudio.avfaudio
