I have had this Roku ultra for several years now nothing has changed in my system but all of a sudden all movies and streaming content have no audio. The audio still works when moving around the menu in the Roku and even going to things like Netflix that have previews has audio. But as soon as I start to play any movie on one of the streaming apps or with Plex there is no audio. If I set the Roku audio output the stereo I get audio back but it's obviously not in surround sound. I have always had the audio settings on the Roku set to auto. HDMI cable goes from Roku to my TV. Then optical output out of the TV to my receiver. This is how I have always had it set up and it has always worked. All of a sudden today I have no audio.

@boydd, in addition to those suggestions, see if you have any of the "Volume modes" enabled while you're playing a video. I've noticed that not all models support them on all videos and you'll get no sound.
