Hello. Let me start by saying this is my first post and if this post has been answered before I apologize. I have a problem. I have a Sony STR-DH540 hooked up via HDMI to my Vizio M50-C1 and my Playstation 4 as well as a Windows Desktop PC. The audio or video will randomly cut out. When the video cuts out the screen goes black for about 3 seconds and then comes back. When the audio cuts out the tv speakers kick back on (They are usually set to off) and then, after about 3 seconds, they turn off and the receiver speakers turn back on. I have each device being controlled with the Vizio TV with ARC turned on. I should also state that this happened with my previous TV, an LG 40 inch HDTV. I have already tried changing the HDMI cable without success. Listed below are the symptoms for each device. Current setup Streaming directly from the TV (i.e, Youtube, Netflix) - Audio cuts out Using the PS4 - Video and audio cuts out, game keeps playing (It's not freezing) Windows PC - Video and audio cuts out, sometimes the resolution suddenly says 1920x1080 and everything is scaled Previous setup Streaming from Amazon Fire TV - Audio and Video cuts out, Videos would pause Streaming from PS4 - video and audio cuts out Streaming from PS3 - video and audio cuts out There doesn't seem to be any rhyme or reason to the cut outs. It's not when anything intense is happening, it's not after a certain length of time, it seems just random. Any help would be greatly appreciated because it's driving me crazy!
