I think your missing sound points to a marginal signal from your aerial although it is strange that it is not accompanied by picture breakup or freezing. Because of the way that digital TV is decoded in your STB and the various forms of error correction employed, if the signal drops for any reason to a value near the threshold for your particular STB/chipset, the error correction can't cope and we get sound breakup/losses and/or picture funnies. One of the blessings of the digital era! I speak as an (very) old analogue TV transmitter man.

Hi Tony,
My theory is it's not the box or the aerial at all, My theory is it's something to due with the switching over from one region to another .
We mainly notice it as I said when the BBC six o clock news is on, then they switch over to east midlands today at 6.30 pm. ( It does happen at other times).
It does not happen in the program, it's just at the start of some live programs. odd !.
If you have two sets , one running analogue and the other digital on the same program you will have a 10 sec delay on the digital one.
Our first box cost £100, our second cost £20 and I have seen some at £11

405 lines - 'H' aerials era
.
When I was very young, I remember my father building 405 line TV's with only BBC on them, Then he made an extra part for one of them, it was a tuner so he could tune into the New ATV TV programs.
I remember seeing the 'Test' transmissions for the new station with all the innards of the TV spread across the dinning table.
