Hi Friends,
I have a Yamaha 677 AVR from last 2 years connected with Q acoustics 3020 , 3000 centre and Wharf DFS surrounds. I am facing a peculiar issue. My tatsky HD+ is connected directly to Yamaha via hdmi with dolby digital + in the tatasky settings. And the tatasky provides the DD+ bitstream for HD channels.
Now , every few days the DD+ bitstream gets downgraded to PCM even for HD channels on its own. I can hear the sound clearly degraded from before. All I do to rectify this is to remove the hdmi from tatasky , clean the hdmi terminal and insert it back. I only clean the hdmi plug of the cable, by blowing some air forcefully and nothing else, only at the tatasky end & not the AVR end. And the system again starts transmitting DD+ bitstream or my Yamaha starts accepting DD+ , I cant tell.
I do not have a problem doing this minor chore, but would really like to know what is happening to the hdmi terminal. Is there any carbon build up , dust or anything else I would really like to know from respected members of the forum. BTW , I upgraded to DAC HDMI 2.0 and the issue is continuing in this cable also.
