Audio drops frequently on new Samsung KS8000 (Firmware 1168) with DirecTV HR54 (Genie C61) and new Pioneer AVR. Drops occur every few minutes and last approximately two seconds. Live TV only. DTV is connected via HDMI 1 on One Connect, with AVR connected to HDMI 4 (ARC). Known issue on various forums. Escalated ticket opened with DirecTV but no response yet. Has anyone heard of conclusive diagnosis yet to this evidently common problem between DTV and Samsung? Or is there a recommended workaround?
