The Roku app on my android phone has started crashing. This started about two weeks ago. I have two Rokus. In my office I have a recent Roku Express feeding a DVI monitor using an HDMI->DVI cable. I've been getting sound through the android app on my phone, but now that fails. I tried an HDMI sound extractor to a separate amplifier, but that doesn't work. I can get sound but the video has a magenta background. Or I can get proper video, but no sound.
The other system is a new Roku Ultra in the living room with an HDMI HD TV and a sound extractor feeding a better amp and speakers than in the TV. It all works fine.
I have rebooted the Roku and the phone. Until I get a real HDMI monitor or TV, I have only the Roku android app to provide me with sound, so I'm dead in the water. How do I fix this?
