Dish HD channels produce low sound

[wolfstar]

Recently purchased a new Home theater sound system <Sony DAV-HDX678WF> and hooked our Dish 622 directly to it via optical connection. **** Note we had this problem before with our old surround sound system hooked up via R/F cables.*** The problem is that the HD channels have a much lower volume output then the reg SD channels. Music and FX sounds are always louder then voice on the HD channels.
Has anyone else had this problem??
Any suggestions?

The TV is an older Phillips 55PP9401 1080i .:tux:
