Odd behavior with hdx

Help. Our aurora lynx 16 has just started some really odd behavior. We haven't changed, upgraded anything this has just started and seems be be getting worse.
The lynx isn't remembering settings. ( yes I set them, turn off/on). It has always remembered settings in the past, not anymore.
When we turn on it selects internal sync and 192 k. If I select other sync or sample rates the front meters meter stuff. Different stuff but is "sees" in and or out signal, with nothing connected. I'll change to our settings ( ext sync) then boot protools. During the boot I hear a click and the lynx will change to int 192. When tools boots it gives a sync error, so I change the lynx and tools settings again and we are good to go. Then when I close tools the lynx clicks again and I get white noise ( fealty fukn loud) coming out of our monitor path.
If I reboot this happens most ( not all) of the time.
Any ideas?
This has just started happening and we haven't changed anything.
