I was querying that too. Huw handed over, to be greeted by silence. They then went through half of an interview with no audio, before it faded up. Even that audio was rather quiet, wasn't it? They then did it again a minute later in a different OB.
I wonder what happened on BBC 1 SD, was the audio present there ? I suspect a meta-data problem between the master OB truck and Red Bee possibly ?
BBC One SD was fine. Looks like a Stereo vs Dolby E issue.
AIUI there is a stereo mix and a 5.1 mix - sounds like the stereo OBs didn't get into the 5.1 mix somehow?
So BBC One SD (taking the stereo mix - NOT a downconvert of the 5.1 mix) was fine, BBC One HD went to silence, and Red Bee had to switch BBC One HD back to an upconvert of BBC One SD to get the audio.
May not be metadata (as per Eurovision 2008) but could be something more to do with the mix. I suspect the main truck monitoring is still stereo (with HD pix) - so the gallery wouldn't have known about the silence on BBC One HD and will have carried on.

The Beeb seem to be having major 5.1 audio problems via BBC 1HD. OB injects into the coverage have no audio, and it looks as if Red Bee are having to switch to an upconverted SD feed during those contributions ?
