ARC is hit and miss which means you have choices to make. Either use the usual optical link or make it a warranty/return issue. Since I know to not count on ARC I go with the usual 5 buck AmazonBasics optical cable. There are some that want to fix ARC. (good luck!)
. . all is working fine, BUT I cannot get the TV's audio signal to route through the home cinema amp and speakers.
it's connected via an HDMI ARC plug, I've selected the TV speaker output to home cinema ARC, and I've selected AUX input in the Harmon Kardon amp. It comes up with a message 'connecting to TV', but never seems to pick up the audio. I've waited 5 minutes for the connection, but to no avail.
Have I done something wrong, or have I been too impatient with the time it takes to find and connect itself?
