I tried to search through Google, but all the options pop-up as sound not working through HDMI. I have a case where I am connecting an AV adapter to a TV, but sound is not working for video ...
I have a brand new LG 50PK950 plasma TV, a six month old Marantz NR1501 receiver, and a couple of computers with HDMI: one desktop with integrated Intel graphics, and a laptop with discrete NVidia.
