Strange issue with Roku 2 (3100X) connected to an HDMI audio/video splitter to projector
I have an old Roku 2 box (3100X) that works fine plugged into a normal TV. I wanted to connect it to my big-screen projector which does not have any audio out. So I bought an HDMI video/audio splitter to try.
I connect the Roku HDMI to the splitter HDMI in. The Splitter audio out goes to my receiver and the video out goes to the projector.
I see the Roku home screen and hear the remote clicks when I move around. My network connection is wired and solid at about 100Mbps.
Here is where the strangeness starts!
1) Netflix: I can select movies from the Netflix menu and select Play. However, the movie never plays, it just keeps going back to the Play/Resume screen.
2) Amazon Prime: I can select movies from the Amazon menu and play them. The video image is fine but for some movies (maybe newer ones?) there is only a loud, continuous buzzing noise and no audio. With some other movies, the audio works fine.
Again, the box connected directly via HDMI to a TV works just fine - all apps including Netflix and Amazon produce good audio and video. This happens only when I'm using the HDMI splitter and projector.
