Hopefully not covered elsewhere. I have a 2011 Mac-mini 8g ram connected via hdmi directly to a Sony Bravia TV The TV in turn connects to a Sony surround sound system and controls this system. When watching a movie on the Mini I will switch to TV to watch something then switch back to the Mini. Occasionally the audio wont be there even though it still shows it as being controlled by the TV. The only way I can get audio back is by rebooting the Mini. Wonder if using the HDMI Detective would cure this issue. Should mention I use the Harmony One to control the setup.
