--- Comment #11 from Chris Dumez <cdumez at apple.com> ---
AudioSourceProviderAVFObjC::process() uses m_writeAheadCount to keep track of how much ahead the writer is compared to media player so that we don't render too early and get out of sync. However, m_writeAheadCount seems to get updated only once, when switching from paused to playing. Maybe when requesting microphone permission (and the audio glitches for 1 second), we'd need to update m_writeAheadCount again?
