Hooking up a new Onkyo receiver to LG C2 77” tv using HDMI 2 port. LG tv has no problem bringing receiver out of stand by mode. Volume control works, jus has no sound. The Onkyo app shows no data connection. Turn tv on/off and data connection shows and sound works. seems like a timing issue from the tv turns on to the connection with the receiver. The receiver needs to be out of stand by before powering up the tv.
