I am usually complaining that the ads are played at much louder volume than the program contents, but not this time. On live off air TV it is fine.
The problem is Netflix and AmazonPrime, plus to a lesser extent catch up content. Catch up content often has the speech swamped by music or sound effects, so I cannot make out the speech. Netflix and Amazon has similar problems, except when then is some noisy action, explosion or gunshot - the volume becomes so loud it is near deafening. SWMBO has just been watching Crossing Lines on catchup, which often has defening passages in it. She says it is my TV.
I have tried various sound settings in the TV, but nothing seems to have helped - has anyone found a fix.
