aliEnRIK:kevinJ:and "Audio DRC" is set to "wide range".
So what does 'wide range' do?
It changes the dynamic range of the audio, making quiet parts louder and thus change the way the audio was ment to be by the director. The "standard" setting is also an 'on' setting, but with less compression than the 'auto' version.
And with a Sony, 'auto' mostly means 'on' . I don't know why they come with the 'BD audio mix setting' to 'on'. That way, buyers end up with HD picture and normal sound and missing (for me) the best feature of Blu-ray
