I have my XB1 audio and video running HDMI through a receiver and the sound is ridiculously low. When watching TV (not through XB1) the volume level is around 19-23 but when I'm running my XB1 the volume level is set to 33-40. Also i get a heartbeat like sound when a game is paused or a Blu-Ray has long pause (Black screen) between titles (like watching a TV show on disk and it's moving between episodes). Finally when playing Wolfenstein: The New Order, the sound kept cutting out for a few seconds. I've tried multiple HDMI cables and various input channels on my receiver. The only thing i haven't tried is taking the receiver out of the equation and using TV speakers, but my TV is surface mounted to the wall and all cables are routed through the wall, so that is quite a task. I've scoured the internet and haven't found this exact issue yet. So any insight would be great.
