I can confirm I also had the same problem on Wednesday night and watched the football via the 92x channels.
Anyone else in Bromley area getting the same??
Didn't pay much attention to it, but notice tonight the sound is still missing.
About to try rebooting the box to see if that will cure it - a bit peeved to think in future we'll have to pay to phone the number to see Ntl have c0ck3d up and a box reboot is in order - surely they could overlay some kind of message to this effect for channels affected...
Yep - rebooted my Samsung (as above) and it's now working... why can't Ntl broadcast a message like the terrestial channels do when they have an audio fault - surely someone back at HQ must have picked this up. If I'm not mistaken, Bromley IS quite important to the network!
