Different sounds in differnt channels!!!

Hi guys,After a long struggle and fighting with distributor sun dth installed in my home today..currently i am receiving all FTA channels..One strange problem i am facing there is no uniform channel sound in sun dth...when i change the channel the sound level for some channels increases and for some channels it decreases..can any one tell me how to rectify this problem? thanks,arun.

I think its not SUN DTH's problem it is your Tv. Turn on your intelligent volume.In some tv it will not be available.I have Sony WEGA.In my Tv, if you turn off the intelligent volume, the volume level for some channels will be high and some channels it will be low.If we turn on, the volume will be uniform

oh ok thank u..i am having old tv.. Still my account is not yet activared currently i am receiving only DDD+..is the different sound in different channels is bcz of DD+.bcz in satcodx website some channels have 196kpbs and some other channels have 256 kpbs...is it bcz of DD+?

In Sundirect channels also the same problem not only in DD+.
