BBC One 2015

The HD feed is not the 'London' feed. It doesn't take London regional news and when Inside Out is on, the network HD feed rotates between the English regional output with playout centrally.

Yes, we all know that, don't we ?

And yet I was watching on BBC1 HD in England and had no sound problems at the beginning at all.

I presume then you just have a bog standard stereo receiver, no 5.1 facilities on it ?
Or was it a D-Sat or DTT thing ? I was using DTT

Well, heaven knows, I just watch it as it comes, through the telly speakers, via Virgin. Though I noticed people on Twitter saying they were watching it on Virgin and the sound was wonky. Seemingly I was the only person unaffected.

You're not using a surround sound amp, just the TV's own speakers ?

I suspect the AAC stream was duff, most receivers will default to that ( regardless whether surround mode is selected by the viewer) However the standard DVB stereo tracks are still there, and were unaffected, your receiver must have been using those

That is correct. I have not fiddled around with the settings at all. Apart from turning it up and down, obviously.

Reports on Digital Spy suggest that DTT in Scotland was affected too, so perhaps it was the same UK wide on all versions and platforms of BBC 1 HD.

Scotland CA Never siad boo, about the troubles

In Wales we had a problem at the end (just before the "keeeeeep dancing" bit) but nothing at the start.

And you were watching on BBC1 HD ?

Yeah BBC One Wales HD
