I have a Sony BDV-F500 home cinema surround sound system and I am having problems with the sound quality when watching Blu-ray movies, particularly action films as the background sounds, especially music soundtracks, are often louder than the dialogue and this makes it difficult to follow what characters are saying.

As a result I am finding myself constantly having to turn up the volume during scenes when characters are talking and then turn it down again as soon as the action starts and explosions start going off etc. as it is then way too loud.

I've tried playing around with the different sound modes i.e. Movie, Music, News etc I've also tried playing with the Audio DRC function switiching it from ON to AUTO and OFF but this seems to make little or no difference at all.

Can anyone suggest a solution?
