Everything was good until about 2 months ago. The problem is when casting recorded videos from my phone to any chrome cast, there is no sound. A grey volume control bar pops up at the top of the screen but there is no way to turn up the volume. This is a major problem that no one seems to want to solve. I have to wait 2 days before I can watch anything that's been recorded. I also have a you tube TV with the remote and that works just fine. This only happens when casting from my phone
