After further troubleshooting, I have found that I can get my Roku Express+ streaming stick to work if I leave it unplugged while both the TV and the streaming stick power on, and then plug it in (wait like a full minute after you turn on the TV and the little LED on the Roku turns on). I am only guessing, but maybe the Roku is checking for HDMI before the TV makes it available, and then falls back into a DVI mode?
NOTE: I only discovered this after testing with an older Roku stick I had laying around the house. It was several versions back from the firmware released today, but the audio and graphisc were fine until I updated to the most recent firmware updates. This leads me to believe that there's a bug in the recent firmware version.
Man, you're a lifesaver. Could not for the life of me figure out how to stop the Roku from switching over to DVI, and waiting a minute to plug in the HDMI cable did the trick. Roku needs to patch this ASAP!
