What are the best settings for a sonos arc and sub combination.  We are finding that the voices are faint and the music/action noises are overwhelming.  I have tried the speach enhancement but that makes the whole thing sound a bit 'tinnie'  

Before this we had a pretty basic panasonic soundbase and to be honest that worked better.

I must be missing something.  This was an expensive outlay for me and my wife just wants to send it all back.
