Have a new 75S M8670pua connected via ARC to my Yamaha RX-A1070 receiver. Had no problem with my previous TV, Sharp, and the Yamaha ARC.

Have a new 75S M8670pua connected via ARC to my Yamaha RX-A1070 receiver. Had no problem with my previous TV, Sharp, and the Yamaha ARC.
Now, starting with everything off, I turn on the TV and the TV starts the Yamaha but the sound does not turn on. If I use the Yamaha remote to do a setup using the Yamaha "On Screen" button, as soon as the Yamaha info shows up on the Lg screen, the sound turns on, wierd. From that point on all sound funtions work great until I shut everything down and try to restart, no sound.
Any ideas would be greatly appreciated.
