After restarting or powering off/on LifeSize Icon600 (latest firmware 3.1.2), I always see "Audio Diagnostics Failed to correct a problem with your audio system." health warning. Icon is connected over HDMI (video and audio) to LCD TV. If I disconnect and reconnect mic, warning goes away and I don't see this audio problem report anymore. Everything else, including audio, is working OK all the time. LCD TV is connected to Icon and powered on before I power on Icon.
