Well, that was interesting...
On Discovery's airing of Highway Through Hell last night (Sept 20, 2021), they were only playing the music audio track with Foley sound effects... the narration and dialog was missing. (I noticed on Twitter they acknowledge they were having technical issues.)
Funny how much music and sound effects that that they add that you notice when dialog is missing... air breaks, crunching, door opening latches, chains rattling, whooshing, etc.
