Firefox Developer Edition latest, v70, Ubuntu 18.04
.ts video plays fine, but audio plays really distorted, very deep like the audio has been slowed down incredibly (even though it plays at same speed). I've tried restarted with no addons to no avail.
Any idea why this file format plays deep sounding from Firefox? It plays perfectly fine when downloaded through mplayer or VLC however, so that leads me to thing there's some issue with a codec or backend lib that firefox may be using.
