My Airtel Hauwei STB RCA Port Problem for Dolby Audio

[Gowmara]

I connect RCA port of HD STB to Home theatre. When i play HD channels, right side speaker sound is low compared to left. Is is problem in DD Audio decoding process in STB?

Note: It worked well in SD channels.

You won't get true Dolby 5.1 sound through RCA. If your HT doesn't have HDMI IN then connect STB via Optical Cable.

I connect RCA from HD STB to stereo Amplifier (R/L). I am not lookking for 5.1 sound. Stereo sound (2 channel) is not working properly. i.e. Right channel is low.
