This is a brand new set, first 2 days was fine. Today after an update, I would play a youtube video and audio drops out totally after around 5 mins in. Video still plays, just no audio. Also happens when watching amazon prime. Also sometimes on amazon prime it just crashes and brings me to HDMI 4 screen (I got a nintendo switch plugged in there, but not turned on). It's frustrating to say the least, could someone please help me with this?
