Sound Not Coming In 2.1 Home Theater ( Connected To L & R Ports Only),
Any Idea Guys?
Similar with 2222 STB.....its not a problem at all.
That L,R o/p is only for stereo.
HDMI o/p port :Can output DD 5.1 and Stereo.
At a time the STB decoder IC can select and process only one sound mode dd 5.1 or stereo........As u select one other one automatically deactivated....
U cannot obtain 100% DD 5.1 in L,R RCA o/p.
In DD 5.1 enabled channels the stereo is a down scaled version of 5.1....so it contains wide dynamic range of audio frequencies than normal stereo......So the HT take the advantage of this and try to re create a 5.1 effect from stereo input (L,R RCA) and may succeed up to 50% only max.(This is the theory behind PRO LOGIC modes)
