So it's a sony tv (not more than 10 years old) and a sky HD box. We don't pay for a package so we just watch the free channels through the box. Lately I've noticed that as channels become HD there is no sound, why would this be ?

At a guess, I'd say it was the HDMI cable; I think you need a 1.4 rating for HD, so try it with a new one.

Check your set top box audio settings
They should be on HDMi -normal.

There's only scant info in your post such as the TV model and whether you're also using some sort of audio system or sound bar , so this is "best educated guess" based on known systems.
The answer is possibly that you have your Sky box set to Dolby audio out, but the TV can't deal with Dolby via its HDMI input(s). Try it on Stereo instead. It won't make any difference to the sound from the TV speakers since most TVs are stereo anyway, but at least the TV can deal with Stereo PCM (digital stereo) whereas it looks like it can't decode Dolby Digital.

You only need a 1.4 rated cable for Audio Return Channel (ARC) and for 4K/UHD content. (It's debatable whether you need 1.4 for 3D because a well-made earlier version will carry the extra bandwidth required for 3D from Blu-ray. Sky's 3D channel didn't use as much bandwidth.)
Regular Sky HD picture runs at 1080i, and every HDMI cable spec from the earliest version 1.0 (year 2002) will cope with that.
This solved it. Thanks so much guys for helping.
Yeah it was the output. It was set to Dolby so I change to normal.
Not true. A Poundland HDMI cable works perfectly on HD with sound.
