Using the Playback Speed Add-On[1] or simple javascript[2] to set video playback rate to > 4x results in loss of audio. Setting playback rate <= 4x restores audio.

[2] document.getElementsByTagName('video')[0].playbackRate = 4.1

MDN says sound should only be muted outside [0.25, 5.0]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/playbackRate
