Test case: https://jyavenard.github.io/htmltests/tests/mse_webm/83910012/ In this sample, we have a 1ms audio discontinuity appearing at t=20ms however due to an implementation detail can be heard at t=2s. In bug 234458, we applied a workaround so that the silence is inserted right when the discontinuity is occurring, which makes it less audible. The audio dropout is due to the audio layer inserting silence when a gap is encountered ; however there's no real gap in the audio content, just that the timestamp in the container are nonsensical. By adopting the key kCMSampleBufferAttachmentKey_FillDiscontinuitiesWithSilence we could tell the audio layer to not insert those silences.
