I've tried sound up, down and in between. The sound level itself is fine. It's the distortion behind the sound that is driving me up the wall.
As Barry said, sound needs to be at 100% on Humax, no ifs or buts. Also I'd set audio output as stereo and not multi-channel in the Humax settings menu.
Your TV may have individual settings for inputs for volume and tone, check these. Also switch off any TV sound processing, i.e. music/sport/movie etc. this includes things like dynamic volume range, dynamic noise, surround, dolby processing etc.
As Graham said, the sound is digital all the way through to the TV. There isn't really anywhere else for distortion to be introduced except on the TV, leave all the enhancements off and tone flat and you should get a clear sound. If you achieve this you should be able to tweak settings step by step later to give you a better personal sound
My partner always tells me I sound muffled when we speak on the phone which bugs me; however she says that to a few people so get a 2nd opinion. My Humax is fed through a sound system and nothing is touched. As soon as I adjust/distort sound settings for a better sound on one programme it'll be worse 5 mins later on a different programme. There is still the odd programme where the sound just isn't right from the broadcaster and tweaking here will only make it worse for other programmes.
