Seeking Help Help Needed! - Buzzing Sound from Tata Sky HD STB

[drshreenivaas]

I have just installed Tata Sky HD Set Top Box (technicolor cardless HEVC STB) few hours earlier. Thereafter, I modified my pack according to my taste. Then, when I switched to HD channels, a harsh Buzzing Sound started coming. If I change default audio to Hindi, then the buzzing becomes bearable, but stll persists. Problem is much worse in english movies channels as there is no option to change language.
I have connected Set Top Box to Tv via HDMI cable & then routed audio to HT via S/PDIF.
I have been persistently calling CC, but unfortunately my details have not been entered in system. Hence CC is asking for either wait till that happens or pay Rs. 300 for technician visit.
I want to know whether anyone has faced similar problem? Are there any settings that need to be tweaked?

Yes, its disgusting, but am unable to do anything about it. These guys should be shot. They say NOISE POLUTION, but no one cares?
