I had been watching a recording I'd made, and then reverted to live TV
which had been set to C4 HD on Freesat. This was about midnight on
Saturday 22 October and 'The Inbetweeners Movie' was playing. The
characters mouths were moving but nothing came out except background
noises (e.g. footsteps, car engines)and music. I watched fascinated
for a bit, thinking it might be some dream sequence, but it carried on
through changes of scene. Then I tried C4 SD channel and all was
normal. Any theories as to what happened here, and why HD but not SD?

Sounds like C4 had cocked up the 5.1 Audio meta-data (which defines
which audio tracks are delivered to whatever your receiver can and can't
support, and/or what you've selected).
HD carries that, SD is just bog standard stereo audio

In the early days of HD, (2008) the BBC messed up the Eurovision Song
Contest on the then BBC HD channel, and only the centre audio channel
(Wogan's voice) went out for the first 40 mins or so.

Surround sound has five channels, the front centre channel often being voices
only, sounds like that was missing.

Happens sometimes on my old Sony system due to dodgy wires.

Quite common for the balance between different channels to be wrong with
surround sound, so over powering music and effects and difficult to hear speech.

No surround sound on SD.

It might have been on the BBC's channel, but wasn't the problem due to the
contractor who run the "presentation" facility?

Well, the BBC seemed to admit liability for it ?

years ago i was watching eurovision on the bbc hd channel (shows how
long ago) and all we got was vocals without music.
switching to sd bbc 1 resulted in the correct sound.

I semi watched* the Dr Who episode on BBC 1 HD on Sunday via satellite
and although my AV amp suggested Dolby digital the sound was somewhat
"flat" and appeared to stereo at best with most of it coming out of the
centre speaker. The following program was also decoded as Dolby digital
and it was like chalk and cheese with regards the sound quality and with
very subtle surround effects.

*Dr Who has really gone past its sell by date - how many times can you
re-invent the daleks and cybermen after destroying them in previous
episodes? Poor scripts and poor acting but it is a kids TV program.

You just re-invent the Doctor instead. He's already had a sex change,
and I understand the next one will have an implied unconventional
sexual orientation, as if this should have any relevance in the
context of a sci-fi fantasy originally aimed at kids.

Not that it makes any difference to me, as I haven't been watching
since the sex change.

When I was young, this was our Saturday teatime viewing for the whole
family and sometimes a school friend of mine as well, and I think it
was similarly popular everywhere else, but recent quoted viewing
figures paint a very different picture today. Just another example of
the BBC failing to understand their customers at all.

Just look at the person who writes the series now, he has an agenda to
promote so little chance of any improvement.
