Ok.. my TV arrived Liao.. but I can't made the TV audio output to my receiver using hdmi arc.. wonder why
HDMI ARC is not quite easy to connect. Many other brands also have difficult because the technology has yet to be perfected. If you have no other choice such as co-axial SPDIF cable, bluetooth etc then tried it by reference to this site.
