Partial loss of sound

[wilkofife]

Watched new BBC Attenborough series 'Wild Isles' last night. Perfect except commentary disappeared after a minute or so. Sound track and music as normal, but no Attenborough ! Quite relaxing actually but a bit bizarre and not what was intended ! Same through the whole programme.
Recorded it, and playback this morning was perfectly normal.
What on earth have I done wrong ?

If it was in 5.1 surround sound it may be the centre channel (which usually carries dialogue) was muted, either accidentally or by a glitch in the Sky box or TV. As it seems to have sorted itself out I would guess it was a glitch.

Absolutely rock solid for me. Humax First gen HDR "not posh" audio using TV Line to basic Amp.

I recall the same at the weekend with Match of the Day.
