The HD channels (apart from ITV HD) have Dolby audio, whereas the SD ones have stereo MPEG audio. The MPEG audio is 'compressed' so that quiet sounds sound louder than they should really do, relative to the loud sounds.

On the other hand, Dolby isn't compressed as much, so that the loud bits sound REALLY loud. But 99% of the time the audio level isn't loud, it's just "normal", which is why Dolby sounds quieter on average. It's a good thing.

However, if "Only the commentary was low,the chat in the studio and adds blasted out", that's a problem at source.
